    Not sure if the title is correct, we were away this weekend in the MH and every couple of minutes the pump would come on for a couple of seconds and all taps closed. I checked the dump valve which was closed but just underneath the Truma there is a black rubber pipe about 1/2inch that had a drip when pump came on, as the ground was full of snow I couldn't get a grat look but I'm thinking along the lines of a PRV maybe slightly passing and the pump coming on to fill pipe work.
    Or could it be a pump fault that over pressures the pipes and the PRV opens, or could the dump valve not be closing properly which in turn causes the drip and then pump fills up again.
    I will hopefully get a look tomorrow if dry so a couple of pointers won't do any harm.

    Hi Gerry

    We had the same thing in our first MH - the pump would come on for a few secs every few hours. We looked everywhere for a leak but never found one.

    Hi Kath,
    Have checked for leak and nothing apart from this small drip dribble near the truma not crawled under for full inspection yet.

    I will be inspecting it before it's used again and is all drained down, do you have any thoughts on what it could be. I assume you do if you think it could be costly.

    We get a drip from a small pipe under our 6E when it's running, apparently it's normal(condensate).

    Does your pump come on as mine does, I have never noticed this before and as the van is bone dry this can be only place water is being pumped to.

    No, no pump running.
    If the boiler is leaking the floor under it will be wet.

    Floor is dry as far as I can see that's what makes me think there may be a faulty pressure valve somewhere or valve is working correctly and pump has fault.

    The pipe from the pressure valve is clear & easily removed. It should be easy to tell if it is passing with the pump on but without the need to get under the van & without the heating/hot water on.
    I have had the intermittent pump issue twice before. on the last van it was the toilet flush solenoid passing, on this van it was a hairline crack in a "Y" piece under the sink area.

    Hi Gerry, our caravan was doing that when we still have some air in the system, ;) and as we only use the shower for the dog it takes a while to shift it. :LOL: Bob.
