    Heard a drip under the van the other day..
    Turned out to be the dump valve leaking by..
    Tried a quick reseat ( opened and closed the thing several times ) but to know avail.
    Anyone know of a fix or replacement ?
    Damned if I am going to pay £79 for a small bit of plastic that for any application apart from motorhome related would proly be about £7 or £8 !!

    Could try backflushing john.

    Stick a hose on the outlet and open the dump valve.
    Back flow may dislodge any grit on the valve seat.

    And failing that, they are simply a valve, there must be something one could improvise with at a plumbers merchants? As long as the hoses fit, shouldn't be too difficult to replace.

    My auto dump valve is a pain it wants to drop the water whenever the temperature is lowish not 4 degrees but just cooler than 10 and it will not reseal until I put a heater on it to warm it right up. If I leave the pump on it will drop the lot. A clothes peg has been brought into action to hold it up.

    Just replaced the very same valve for a friend of mine, unfortunately they are unserviceable as techno said they're about £28.

    No need to strip the valve to clean it.. simply soaking overnight in a hot water/white vinegar solution will remove the limescale..

    if that doesn't work.. then perhaps replacing is the only option..

    but before I forked out 30 quid I would still strip and see if it could be repaired.. nothing ventured .. etc

    I'm going to order one of them also. Mine works perfectly at the moment, but in a year or so when mine fails, I know I will have forgotten about this thread! :D

    Mine is the same (auto) and I also use a peg to keep it closed.

    I've got an electric Automatic dump valve going spare, surplus to requirements.
    Swap you for a BBQ gas point.

    Bloody ebay nutters.. That thing ended at £28 inc post.. about the same as a lot of places sell them new anyway !



    Depends on what type of gas point you want mate ?
    I do have a spare.. It is a fly lead type that I used to have t'ed in to the low pressure side of the regulator
    Can supply all pipe and T piece if any good ?

    Got a picture? Not quite sure what you mean.
    I would like the one that fits into the Bodywork, so that you don't have to open the door. Can I use the one you have like that?

    Hi Techno 100 and Jaws,
    Looking at the valve on eBay that you showed, it looks like the one we have on our new Chausson 610 but I thought it was the frost safety valve, if it is not then we don't have a frost safety valve on our MH, can you or anyone else inform me whether Chausson don't now fit them as standard? Be pleased with the answer.
