    That taped up pipe is likely the reason.

    Caravan water system will be pretty straightforward,  Water comes in at side of van then pipe splits to supply cold to kitchen and bathroom and cold feed to water heater.

    Then from water heater a pipe will run to the hot taps in kitchen and bathroom.

    Do you get any water at all from the hot taps?

    Can you access the tap tails and trace the pipework back towards the water heater ?

    Where is the pipe that is not connected to anything?

    Are there any wires coming from the taps?  If so, you have microswitches which activate the pump.  If any of those are broken, opening that tap will not turn on the pump.  Does the pump run when you try each hot tap in turn?

    Do you have the handbook for the van?

    If not, you can download from Swift, here is the link.....

    Unfortunately the oldest one in the archive is year 2000, but it will maybe give you an idea of the systems.  Electricals tend to change faster than the water side of things.

    Swift also have their own forum, SwiftTalk, which is good for advice, so you could join up on there too.

    Martin, as KjellNN says taped up pipe probably the problem.  No end should be taped they must go somewhere - a tap or heater then tap.  Just a thought, maybe a previous owner has put a cold only tap where once there was a mixer one.  If you bought your caravan
    from a dealer and it is still under any sort of waranty, back to him.  Try the following

    Any water from hot taps?

    If yes - is heater on. If on gas you should hear it; if electric after a few minutes you should feel the hot exit join getting warm.  If water does not heat up problem with heater - could be a fuse or connection somewhere.  Are you doing this with a battery
    in your caravan - a 12 v is needed.

     If no; have you closed the drain valve!  Try again and turn a hot tap on, is the pump working.  If it is wait for a solid flow of water from the tap, do this for all hot taps and shower.  If water but not warming up problem with heater.

    hi all thankyou for your replys i wont have chance to look at caravan untill weekend but will let you all know,i think it is the pipe which is blocked off as when i turn hot tap on the pump starts and i can hear the water being pumped but then stops as if
    it is being blocked.

    if i could just find a picture of the layout of the piping that would be great.

    many thanks martin

    I'm afraid you are most unlikely to find any pictures.

    Caravan pipework really is very simple, best way to figure it out is to start at the water inlet and follow each pipe.

    I would also get a bucket, untape the end of the pipe and see if you get any water out of it when you turn on a hot tap.

    As to why anyone would cut off the water to the hot taps (is it ALL the hot taps, you must have 3 of them), one reason could be a leak in an inaccessible place like somewhere behind the shower.

    Sorry, I meant a leak from a tap, or a pipe, that the previous owner was unable to fix, so disconnected the water instead, not a leak from outside.

    It is a scenario I have heard of before, so if you manage to connect everything up, just be careful to check all along the pipework.

    They may have blocked it off because it was left with water in over  the winter, the water froze and expanded, and 'blew one of the seals'  which caused the a leak.  Instead of replacing the problem tap or junction they may have just taped up the feed to
    any of the hot taps.

    As had been said, you need to trace the supply from the inlet, through the heater, and onwards, to find where the problem is.  Most parts are easy enough to replace, and not too costly, so you should hopefully soon have a working system!

    we have found with our swift charisma that we do not do things in a set order then we get no hot water coming through! ie if I am being impatient.   I need to keep my hands off the water taps etc until the aquaroll it filled up and connected.  Once this
    has been done I can then switch on the pump and the hot water will eventually come through.  First trip of the season is always the same and we make sure we do things correctly.   We actually called the dealer the first time as we were stumped why no hot water
    coming through plenty cold but not hot - easy remedy unplug electric hook up from bollard and wait 5 minutes then plug back in - duly did that and it worked hot water.   Not sure if maybe something as simple as this but might be worth a try.
