jonesthenuke Posted May 19, 2017 Report Share Posted May 19, 2017 We have a Jabsco 50880 as a shower drain pump. Its a diaphragm pump and generally works very well, but I have now had the inlet valve fail twice in a year. The failure is a split in the rubber around part of the lip at the circular end. This seems a short service life as we only use the boat for holidays, so its not much use in that time. Perhaps this is why they are called Joker valves? I can only locate spares as part of a spares kit at about £20. Jabsco list just the valve at approx £2 but I cannot find a stockist. As I bought a spares kit last year to get just a valve (I did not change the diaphragm) I would rather buy just the valves. Does anyone know of a stockist ?

Tony Brooks Posted May 20, 2017 Report Share Posted May 20, 2017 It's an import but from the EU - how about this https://marineersatzteile.de/EN/Jabsco-50885-0000 but its over 5 euros. Also an Ausi site but this time 17 A$ Go on, get a Whale, you know it makes sense. Link to comment Share on other sites More sharing options...

Why can't you buy it from jabscoshop.com at £1.34 + £4.00 shipping + VAT = £6.41? Or £8.02 for 2. Link to comment Share on other sites More sharing options...

I looked there first and could not find it so either a poor website or a decision not to sell in the UK by someone. Link to comment Share on other sites More sharing options...
jonesthenuke Posted May 27, 2017 Author Report Share Posted May 27, 2017 Problem solved they are now back in stock at the jabsco shop. This surprised me as I have looked multiple times only to find them out of stock. Thanks to this forum I looked again. I have bought four. if the failure rate remains the same I will swap to a Whale pump, but this is irritating as the Jabsco should last longer than it does. I am also considering putting some mastic around the valve when I next install one as they seem to fail in the same place and I guess they are overstressed.
