    Fitting Floë Induratec 636 - How do I fit Floe 636 to a caravan with an onboard cold water tank

    For connecting Floë to a caravan with an on board fresh water tank and an inlet from the outside water barrel, we have created a chapter on the DVD called, “fitting to the complicated layout”, so take a look for this in the troubleshooting chapter of the DVD.  On this, we connect the airline tee to the inlet from the outside barrel and for draining down, make sure the direction of water is set to bringing in water from the outside barrel.

     

    For Floë units that will not stop running and are not building up in pressure, see Using Floë Induratec 636 – Floë Keeps Running and will not stop

    Using Floë Induratec 636 - Floë Keeps Running and will not stop

    When a Floë unit does not stop and you believe that it is not pressurising the system, the most likely reason is that there is an air leak somewhere in either the Floë airline setup, or the vehicle water system.

     

    So, we need to make sure of a few things first

     

    1. Make sure all taps are closed
    2. Next you will want to check the dump valve for the water heater.  This little yellow lever is designed to be closed by flicking it down with your index finger, however, most people lower it down with the thumb and forefinger.  Now, the problem with this is that, if you push the lever down to the floor too much, it will lift the back of the hinge up and out of the floor and this opens the valve again.  So, try lifting the yellow lever up just a fraction.  This should close the valve and then Floë should stop.

     

    Now, if this doesn’t work, there could be an air leak due to the seals in the Floë assembly connections.  What you need to do is check first that the box works normally, without connection to the water system.  So,

     

    1. Remove the little connector under the box, which normally connects the stump of airline under Floë to the long airline
    2. Switch Floë on and hold your thumb or finger over the stump of airline.  See if the box stops after a second.
    3. If not, contact us 028 9247 4040, as there is a problem with the Floë unit. This is rare though.
    4. If yes, the box works, so there is a leak somewhere. So round the ends of hose with your fingers, wet the hose ends and reattach.  Sometimes cutting makes the hose or pipework oval shaped with the cutting pressure used, leaving a poor seal.
    5. Now, to test that connector back at Floë, we need to disconnect the other end of long hose and hold your thumb over the end of the hose. Holding thumb over the ends of the push fit connectors will not work, as they don’t work that way, it needs to be the hose ends.
    6. If the box stops /starts, then reseating the hose back at the Floë fixed the problem.
    7. If not, try to reseat those connections again back at the Floë unit and try again
    8. If the problem persists, remove the tee from the water pipes.
      1. The tee is made up of 3 parts, Non Return Valve (NRV), Connecting hose and Tee.
      2. Take the assembly apart, Round off the little hose piece, wet the ends and reseat into NRV and Tee
      3. Reassemble the tee and make sure to place the red end of NRV beside the tee in the middle of the assembly.
      4. Make sure the cut ends of the main water supply pipe are not oval. They are a bit tougher, so wrap and protect the ends with a cloth and shape with pliers.
      5. Reseat all the connections
    9. Retry and if problem persists still, contact us on 028 9247 4040.

    Fitting Floë Induratec 868 - Can I Remove the Drain Valves Under The Caravan / Lodge

    The short answer is yes, but we just to explain why.  The drain valves under a Caravan or Lodge date back to a bygone era of draining down.  There were two schools of thought at that time.  Either open the valves and open a tap inside so gravity alone will allow the water to come out.  (This really never worked).  Or, open the valves and try to use a compressor or pump airline attached to the tap inside, to push the water out in reverse from each tap, down through the system and out of the drain valves.

    This process was used for years, but due to one way valves in the shower and boiler, it is nearly impossible to carry out a proper draindown without dismantling these devices.

    The modern drain down involves following the direction of the water from the outside in and pushing the water out of taps and outlets.  If you can see that it has been removed, it is removed.

    Now, water doesn’t travel anywhere randomly.  It goes to taps, toilets, showers, outside taps, washing machines and dishwashers.  If you drain each one of these fully, then the water in the system has been removed.  Therefore, having the drain valves connected are now surplus to requirements.  They are an appendix or an additional leg that can be removed.  As you will push the water out of the outlets, you do not need the drain valves.

    However, the first time you use Floë, you will want to drain the drain valves at the end, just to see how much is in there.  If you find there is a cup full, then you might want to consider draining them each time, or removing them.  If there is only a quick spray of water, then you might want to just wrap foam lagging around the ends.  It’s a decision call.

    Should you wish to remove them, you will probably need to remove the lagging around the pipes first.  If you find that the pipe to the drain valve is connected to a tee, then replace the tee with a 90 degree right angled elbow.  This will remove the drain valve pipe, but complete the system again.  You can also cut the pipe close to the connection and use quick push fit stop ends.  The removal of the pipe completely is not necessary, as it can simply be left where it is.

    Using Floë Induratec 868 - Floë Keeps Running and will not stop

    When a Floë unit does not stop and you believe that it is not pressurising the system, the most likely reason is that there is an air leak somewhere in either the Floë airline setup, or the property water system.

     

    So, we need to make sure of a few things first

     

    1. Make sure all taps are closed
    2. Make sure none of the toilets have been flushed before the drain down process
    3. While Floë is running, lift the lids of the toilet cisterns and listen to the inside. If there is a hiss, then there is air escaping from the cistern mechanism. If the toilet is the modern type, try lifting the little float that rises and falls while it flushes. If it is the old ball cock style, lift up the ball float up and see if hissing stops.  In the DVD troubleshooting we discuss what to do with this, but it would involve using a length of stick/pipe to prop up the ball/float to carry out the draining process, then replace the inexpensive mechanism at a later date.

     

     

    Now there could be an air leak due to the seals in the Floë assembly connections.  What you need to do is check first that the box works normally, without connection to the water system.  So,

    Using Floë Induratec 868 - Can you explain how to drain a modern style toilet using Floë

    Hopefully, we can assume you know how a traditional ball valve in a toilet works.

     

    • Flush toilet
    • Ball cock in cistern falls down
    • The valve opens to let more water in
    • The ball cock then rises and shuts off valve when the water reaches the fill line of Cistern

     

    Well, the modern ones work in exactly the same way, except they have a little float in the mechanism, but we need to identify the float.  So, before you carry out a drain down and while your water is still switched on, as a trial, take the cistern lid off and look at the mechanism inside.

     

    Then, flush the toilet and you will notice a little float inside the mechanism that will drop down to the bottom of the cistern.  This will open the water inlet valve in another part of the mechanism, to refill the cistern.

     

    Although these modern toilets all work the same, there are many kinds of mechanisms out there, so we don’t want to direct you to a specific part, but watch carefully as the water drains from the cistern.  A float will definitely fall.  When you see the float, just remember where it is.  So, once you are ready to carry out a drain down, you’ll know where to find it from now on.

     

    Draining Down

     

    OK, so when draining down, you will want to drain the pipe leading to the toilet as part of the process.  This is ignored on many paid for drain downs by the way.  So, when Floë has pressurised the system, simply press down gently on the little float.  Go easy, as the water level may rise with the water coming in from the pipe.  But do this until the water has come out and only air is being forced into the cistern.  It only takes a second to drain and you’ll probably notice the water rising excessively.  This is the air doing its job.

     

    Remember that draining the pipe to the toilet is only part of the draindown and that the draindown is only part of the winterising.  Therefore remember, do not flush the toilet after draining the pipe leading to it.  Only when you have completely finished the entire drain down process around the property, can you carry out the rest of the winterising, which involves flushing the toilets and putting half a glass of antifreeze down into the toilet bowl and a half a glass into what remains in the cistern.

     

    Now, rarely some cistern mechanisms can be problematic.  If you find that after you drain the toilet pipe into the cistern, that you can no longer build up pressure, then you have a couple of options.  This is very rare, but happens from time to time.

     

    • Fill the cistern with more water to raise the float higher in the water, shutting the valve
    • If this does not work, hold the float up with your hand to close the valve and ask someone to drain the other outlets.
    • If there is a shutoff valve half way up the pipe to the cistern, turn it off for the remainder of the drain down and back on again when finished

     

    In this rare situation, it is the water in the pipe that makes the seal and without it, some cistern mechanisms can be a little flaky about staying shut.  In this instance, it is advisable to leave the toilets to the end of the drain down, however with an ensuite toilet, you may need to have someone hold the ball valve, or float up, or turn the shut off valve half way up the toilet pipe to off, just for the last toilet.

     

    As a complete solution, it is advisable to replace this part of the toilet mechanism for about £12-16.  Simply take a picture of the cistern to a hardware store and they can replace the part for you.  Floë is simply showing a future problem, as air will escape more easily than water.  In time, this will end up being one of those toilets that drips and refills continuously.

    Using Floë Induratec 868 - Draining the Boiler and Discussing the Radiators

    From the 1960s and 70s, static caravans have had water heaters or geezers.  Today it is the same, but with the introduction of central heating radiators, most modern caravans today will have what is known as, a gas combination boiler.

     

    A combination boiler or combi for short, is one that will heat the fresh hot water for washing and bathing as before, but they will also heat the water in the radiators.  Now, without getting too technical, think of a combi boiler as being in two halves.  The top half looks after the central heating and the lower half looks after the heating of your hot water.

     

    In the top radiator half, there is a device slightly smaller than a house brick called a heat exchanger (HE) and inside it looks like honeycomb.  The water from the radiators is passed through the HE, where it is heated and then a pump pushes the water around the radiators in a closed and sealed loop, until it eventually comes back into the boiler again, where it is heated and off it goes to the rads once more.

     

    Now, since central heating was introduced to caravans, the manufacturers have always pumped antifreeze into the loop of radiator water, so that it is protected against winter.  You don’t need to do anything with your radiators or indeed this part of the boiler in winter, however, next time you get your boiler serviced, get the plumber to check that there is enough anti-freeze in the loop.

     

    This brings us to the lower part of the boiler which looks after the heating of your fresh water.  Here there is another Heat Exchanger (HE) like the first, but specifically there to heat the fresh cold water.  Basically, when you open a hot tap, the mains water pressure pushes cold water into this HE, where it is heated, and then comes out of the HE as hot water, that travels on to the hot taps. This is on demand water heating.  Very simple, but very effective.  I you don’t have a combi boiler, but just a water heater, this works exactly the same and the rest of this section relates to both combi’s and water heaters

     

    So, what about draining down.  Well, we have already established that the radiator part of the boiler does not need any intervention, however, the lower fresh water side is vulnerable against frost.  You cannot put any anti-freeze (AF) into this water, as you would be polluting it.  People have tried to introduce Food Grade AF, but it has not been passed by the Water Regulations Advisory Scheme (WRAS) and is therefore illegal.

     

    So, we need to do something about this water, as it will freeze and damage the boiler.  In days gone by when engineers were trying to drain the system in reverse, they knew that there is a one way valve in the boiler.  This allows water to travel as cold into the hot side, but not the other way around.  Again, that would be polluting the cold water system.  So, to drain down they would have to remove parts of the boiler to drain it out.  Incidentally, there is a one way valve in the shower mixer valve, which is why many engineers remove them and lay them on the floor of the shower.

     

    However, Floë is different.  Whether it is using our Portable Water Drainage System that connects to the outside tap, or our new Floë Induratec 868, both will remove the water by pushing it through the system and out of the taps, following the natural flow of the water.  By following the natural flow, the cold water is pushed through the boiler and on to the hot taps.  So, by draining one hot tap, you will have drained the boiler.  There is absolutely no need for dismantling the boiler or the shower.  As a matter of fact, there is no need to go near the boiler.  It will be drained as part of the process.

     

    Better yet, in a typical caravan, there are 4 hot outlets to drain, Kitchen, Bathroom Wash Hand Basin, Shower and the En-suite sink.  Therefore, when all four have been drained, you will have drained the boiler 4 times.

     

    As an additional feature, it is worth draining the hot taps through the summer once or twice.  On a normal draindown, the air going through the boiler will disturb any sediment that naturally gathers in the Heat Exchanger.  This is nothing like the rust sediments picked up by magnets in the central heating side.  As we have discussed, that is a separate system.  But left unchecked, this sediment will naturally increase and make the boiler burn inefficiently, costing more on gas and will eventually ruin the HE.

     

    However, if you drain the system and especially the hot taps, Floë will disturb the sediment.  If you then turn your water back on and run the hot taps while the sediment is disturbed and jiggled up, the new water will flush this sediment out of the taps.  The result is a more efficient boiler that can save up to 15% on your gas bill and you will extend the life of the Heat Exchanger indefinitely.  As mentioned, this is something you’d want to do through the summer season.  Very effective though.

    Fitting Floë Portable - Where should it be fitted ?

    There are two types of water systems in leisure and permanent properties, those with direct mains water straight to all of the cold and hot taps (Closed Systems) and those properties that use a cold water storage tanks in the attic (Open Systems)

    For this question, we shall be concentrating on Closed Systems as, there are a number of places you need to winterise on Open Systems.  Also, its must be iterated at this point that, you should consult a qualified plumber for using Floë on an Open System.

    In a Closed Direct Mains System, cold water comes in to the property from the outside.  It will travel through a shut-off valve to be able to isolate the system.  It then splits into two branches.  The first goes as fresh water to all of the cold water taps, kitchen, bathroom, toilet, washing machine, dishwasher etc and of course the outside tap.  The other branches off to the boiler, then to the hot taps in the property.

    Floë should be connected to the main water line on the property side of the stopcock.  This can be done a number of ways.  The most popular is to connect it to the 3/4″ thread of an outside tap, as long as it is also been connected on the property side of the stop valve.  If you dont have an outside tap, then you can fit either a washing machine tee or a self cuting tap on the main water line, again on the property side.  These are available on the website and can also be used as an outside tap as they have the same 3/4″ thread.  Further information can be found on the DVD that comes with Floë.

    Fitting Floë Portable - I dont have an outside tap. Can I use the Static/Lodge Drain Valves

    The whole aim of Floë is to build up air pressure and follow the natural flow of the water from the outside of the property.  This means that the water is being pushed from the stop valve outside, up into the property and out of each tap and outlet.  This ensures that the user can see that all water has been removed.

    Following the natural flow of the water also means that the water is effectively chased through the system components in the direction that is naturally intended.  The boiler and the shower both have one way valves inside them, which basically means that, cold water can enter the boiler, made hot and travel on to the hot taps, however, the hot cannot travel back into the cold system again.  By using Floë, water is chased through the boiler at low pressure and on to the hot taps.  For every hot tap you drain, you have drained the boiler.  So four hot taps, four boiler drains.  On a Floë draindown, you do not need to touch the boiler.

    In the case of the shower, again, the water can travel out of the shower valve and then the shower head, but cannot travel in reverse.  This is in case the shower head is left in a kneeling bath.  If someone were to turn a tap on in the kitchen to fill the kettle say, there is the rare phenomenon of “Back Siphoning”, where the water in the bath could be sucked back up into the system.  This is very rare though.  Nevertheless, bylaws dictate that one way valves are fitted.

    Whatever the situation, it is important to drain a property following the natural flow of water.  Should a person try to drain in reverse, by attaching an airline to a tap, or using the drain valves outside, then the water in the boiler would have to be removed manually, which is a pain and not for the casual DIY’er.  In the case of a shower, the shower valve is usually removed in these drain downs, which is punishment that the attaching threads were never meant to endure.  Also, unless  reconnected, the water system is rendered useless, with two ugly holes in the wall of the shower

    If you don’t have an outside tap, then you can always fit a Compression Washing Machine Tee or a Self Cutting Tap (both available from us in the static/lodge section).  You would fit any one of these on the main water line leading into the property.  These will allow you to get a clear airway and can be fitted anywhere on the property side of the stopcock.

    By fitting here, you can be assured that you are facing the correct direction and following the natural direction of the water, that all taps and outlets can be drained and the biggest advantage is that you don’t need to manually drain boilers or dismantle the system in any way.  This means that the draindown is incredibly quick and that, without reconnections, you are free to enjoy your property through the winter months, draining when and as often as you like.

    Fitting Floë Portable - I am using an outside tap, but cant get air through it and the compressor builds to 30psi in 1 second

    Sometimes when you try to push air into an outside tap, you will find that the compressor shoots up to 30PSI in about 1 second.  This means that there is a blockage.  A good way to check if you have a blockage is to open a tap inside and try the compressor outside again.  If air is getting in to the system, there should be gurgling in the tap, If not, there is a blockage and you will hear nothing.

    There are a couple of reasons and solutions for this

    1. Some outside taps have one way valves fitted to them, which allow water to come out, but not allow air to travel back.  You will know this if you take off the hose connector and look up inside the mouth of the tap and you see a little white valve insert. This is a one way valve.  There will also be another in the back of the tap.  The solution is to either replace the tap, or remove and modify it.  To remove, first turn the mains water off, unscrew the tap from its backing plate.  In the front and back there will be a little circular clip holding the little white cartridges in place.  Remove these by using the pointed end of a knife, to slip under it.  Then remove both white cartridges.  When replacing the taps, wrap plumbers PTFE tape about six times around the threads in a clockwise direction and screw the tap back in.
    2. If there is no white insert, but the tap still won’t let air travel through, there could be a chance that the brass stem is broken inside.  This tap cannot be repaired and should be replaced with a typical outside tap without one way valves.  You can tell it is broken, by turning off the water supply, remove the tap and turn the tap on while it is in your hand.  If you shake the tap and it rattles, it is broken inside.  For a quick draindown, you can use this tap temporarily though.  Wrap plumbers PTFE tape about six times around the threads in a clockwise direction and screw the tap back in, but leave it upside down.  Open the tap fully while the water is off and tap gently with a hammer of similar weighted tool.  This should make the broken piece fall back down into the tap and open the airway.  Screw Floë back on, open a tap inside and try to enter air.  If air is getting in to the system, there should be gurgling in the tap, If not, the tap is still blocked and should be replaced, if there is gurgling, close the tap and continue with the draindown.  The tap should still be replaced though.

    You can of course abandon this tap and fit a Compression Washing Machine Tee or a Self Cutting Tap (available from us) on the main water line leading into the property.  These will allow you to get a clear airway and can be fitted anywhere on the property side of the stopcock.

    Using Floë Portable Water Drainage System - Compressor Stops after a Few Seconds, But No Water Comes Out of the Taps

    1. If only after a couple of seconds the compresssor stops, then there is a problem.  First of all, make sure you are not connecting to a non return tap (see below) or there is not a non return valve after the point of your connection.  When connecting the tool to a tap or fitting, you should ensure that the tap has been opened and run dry before positioning the tool.  Also, make sure that the tap is open and that the tool is seated well, to allow the compressed air to pass through.  In addition, sometimes older taps stick inside, so twist the head left and right to loosen the inside of the tap. (These problems are discussed further in the Essential Winterising Techniques Series of How-to DVD’s)
    2. With static caravans, sometimes a compressor will stop at 30PSI(2BAR) or reach that pressure and continue very quickly.  Check your mains feedpipe and see if it lies on the ground before rising up to the tap.  If this happens, then when you turn the tap on not much will come out and the remaining water in the line will be topped up to the tap itself.  Try opening a tap inside first, then compressing again.  As the compressor pressurises water should be pushed out of the tap inside.  If not go to the next step.
    3. Another issue we have found is that some older taps have a little closing lid inside the tap for the purposes of shutting off the water when the tap in turned off.  This lid disconnects from the tap handle inside and falls down into the tap (ie it is broken).  Ordinarily this would not be noticed, as when the tap is turned on the water pressure pushes the lid out of the way and water flows from the tap.  However this is a problem for winterising as when we apply pressure in the opposite direction, the lid falls down again and acts like the tap has been turned off.  You will know this is happening if the compressed air pressure starts to reach a high level very quickly.  This is a faulty tap and should be replaced with a normal outside tap and not a non return type.  Remember to use PTFE tape on the tap threads.

    Fitting Floë Induratec 868 - Can I Remove the Drain Valves Under The Caravan / Lodge

    The short answer is yes.  But just to explain why, the drain valves under a Caravan or Lodge date back to a bygone era of draining down.  There were two schools of thought at that time.  Either open the valves and open a tap inside so gravity alone will allow the water to come out.  (This really never worked).  Or, open the valves and try to use a compressor or pump airline attached to the tap inside, to push the water out in reverse from each tap, down through the system and out of the drain valves.

    This process was used for years, but due to one way valves in the shower and boiler, it is nearly impossible to carry out a proper draindown without dismantling these devices.

    The modern drain down involves following the direction of the water from the outside in and pushing the water out of taps and outlets.  If you can see that it has been removed, it is removed.

    Now, water doesn’t travel anywhere randomly.  It goes to taps, toilets, showers, outside taps, washing machines and dishwashers.  If you drain each one of these fully, then the water system has been removed.  Having the drain valves are now surplus to requirements.  They are an appendix or an additional leg that can be removed.  As you will push the water out of the outlets, you do not need the drain valves.

    The first time you use Floë, you will want to drain the drain valves at the end, just to see how much is in there.  If you find there is a cup full, then you might want to consider draining them each time, or removing them.  If there is only a quick spray of water, then you might want to just lag them, with foam lagging and taped up.  It’s a decision call.

    Should you wish to remove them, you will probably need to remove the lagging around the pipes first.  If you find that the pipe to the drain valve is connected to a tee, then replace the tee with a right angle elbow.  This will remove the drain valve pipe, but complete the system again.  You can also cut the pipe close to the connection and use quick push fit stop ends.  The removal of the pipe completely is not necessary, as it can simply be left where it is.

    Using Floë Induratec 868 - Floë Keeps Running and will not stop

    When a Floë unit does not stop and you believe that it is not pressurising the system, the most likely reason is that there is an air leak somewhere in either the Floë airline setup, or the property water system.

     

    So, we need to make sure of a few things first

     

    1. Make sure all taps are closed
    2. Make sure none of the toilets have been flushed before the drain down process
    3. While Floë is running, lift the lids of the toilet cisterns and listen to the inside. If there is a hiss, then there is air escaping from the cistern mechanism. If the toilet is the modern type, try lifting the little float that rises and falls while it flushes. If it is the old ball cock style, lift up the ball float up and see if hissing stops.  In the DVD troubleshooting we discuss what to do with this, but it would involve using a length of stick/pipe to prop up the ball/float to carry out the draining process, then replace the inexpensive mechanism at a later date.

     

     

    Now there could be an air leak due to the seals in the Floë assembly connections.  What you need to do is check first that the box works normally, without connection to the water system.  So,

     

    1. Remove the little connector under the box, which normally connects the stump of airline under Floë to the long airline
    2. Hold your thumb over the stump of air line, switch Floë on and see if the box stops after a second.
    3. If not, contact us 028 9247 4040, as there is a problem with the Floë unit. This is rare though.
    4. If yes, the box works, so there is a leak somewhere. So round the ends of hose with your fingers, wet the hose ends and reattach.  Sometimes cutting makes the hose or pipework oval shaped with the cutting pressure used, leaving a poor seal.
    5. Now, to test that connector back at Floë, we need to disconnect the other end of long hose under the property and hold your thumb over the end of the hose. Holding thumb over the ends of the push fit connectors will not work, as they don’t work that way, it needs to be the hose ends.
    6. If the box stops /starts, then reseating the hose back at the Floë fixed the problem.
    7. If not, try to reseat those connections again back at the Floë unit and try again
    8. If the problem persists, remove the tee from the water pipes.
