    My van's water pump (Shurflo 2095) has started leaking from where the pump head joins onto the main body. When the pump is running you can see water seeping out all around this join - at other times it doesn't leak. It is working normally otherwise.

    According to the exploded diagram in the pump manual, there is what looks like a gasket that presumably is meant to seal this joint. However, no spare part is listed for this gasket - only major parts of the assembly or the complete pump head. Does anyone know if it is possible to just replace this gasket?

    Pump is still under warranty (for about another month) but by the time I drag the van back to the original dealer I might just as well pay for the pump to be repaired (or replaced) locally. Also pump is located under the Truma boiler (which is on a shelf above it) with little room to get at it (a Hobby design classic :RollEyes:) . By coincidence, the boiler is having to come out next week to have its electrical element replaced (under Truma warranty) so that would be a good time to get to the pump. There seems to be enough room in the locker to maybe relocate the pump to make it more accessible in the future. Or possibly (if pump is replaced) to repair the gasket once the old pump is out and reinstall it alongside the new one with a switch between the two so that I have a 'standby' pump all ready for when the next one fails. :RollEyes:

    Any thoughts on repair or replacement, please? :Smile:

    mine also leaked in the same place.
    i used Blue Hylomar automotive gasket cement to seal it.....previous owner had used silicon sealant which didnt work.

    Hylomar is toxic but the minuscule amount needed hasnt caused any health problems.

    many thing on those pumps, other than the valve block, is supposedly not replaceable including the microswitch....dont believe it, the manufacturers dont want you to repair it...they want you to buy a new one.

    A new pump is less than £50.00.

    Buy one and keep the good bits off the old one!:BigGrin:

    A long term leak can cost you loads if water gets into the floor, is it really worth scrimping on preventative repairs?:Eeek:

    Thank you for that. I've just looked up Hylomar Blue and it's readily available. Not worried about toxicity as I don't drink from the on-board water system. :Smile:

    Would be happy doing that job myself once the pump was out but because I live in the van and don't want to be without water, I think I would need to get the pump replaced first and then keep the old one for future use.

    Our posts crossed - I'm already thinking along those lines. :thumb:

    With the constant on, off and vibration the nuts do sometimes just loosen enough for them to weep. Try just nipping the screws a little.

    if my cars cooling system springs a leak, i fix it
    If my household plumbing springs a leak, i fix it.
    If my RV water pump springs a leak, i fix it.

    To renew the pump just because it leaks is beyond me.

    If it continues to leak i would replace it without question but to replace for the sake of it is environmentally unfriendly.....and not everyone can afford to replace everything which just stops working.

    I did that first, Dave. Managed to tighten one very slightly but unfortunately it made no difference to the leak. :Sad:

    I get what you're saying but in my case if I whip the pump out while the engineer has the boiler out and try a repair only to find out once everything is back together the pump still leaks, then I've lost the opportunity to get the pump replaced easily. Things are a bit different when you live in your van - I can't just tinker with it from time to time when it's not in use. It's always in use! In any case, I'd keep the old pump and try to repair it so that I had a replacement for the future.

    Maz, This is a regular problem in Spain where they put a lot of chlorine in the water. The hardness of the water eventually forces the seal between pump and motor. We call it calk. If you are are able to remove the pump and break the seal you will find the white powdery stuff thats causing the problem. Get a small paintbrush and remove it with white vinegar, then smear a LITTLE Vaseline on the joint and re build. Making sure the screws are tightened properly. If this does not work, then am afraid its a rebuild kit.

    For the price of a new pump I would change it whilst you can easily get at it and keep the old one as a spare.

    That will guarantee that the new one will never go wrong:thumb:

    Yes, I think that's the way to go. I'll be ringing the workshop tomorrow to ask them to order me in a pump as well as the Truma element. :Smile:
