Jabsco Manual Pump Assembly f/29090-Series

Works like youd expect a Jabsco flush valve (not the best product but not much better choices). I just cant believe marine prices, absolutely outrageous that this thing costs $90.

Save your fingers and frustration. A long (10+) phillips screwdriver would make instillation in tight spaces much easier and reduce cursing. An extra slotted flange screw is supplied free, but probably will not be needed. Be sure to keep your 4 existing (different) base screws, you need to reuse them

Need to take care when fitting to the waste hose. The joint will leak if the hose angle puts pressure on the toilet outlet.

Bolted right up on my 89 bayliner. Works like a charm!

This assembly kit is about the same cost as the bag of loose parts you can buy to overhaul your pump but the kit is easier and quicker to install plus you get a new housing. The kit also includes a lock handle that most of the older models doesnt have. This lock feature eliminates the possibility of flooding your cabin from water backing up thru the toilet.

I had to disconnect all the related hoses in order to gain full access to the pump assembly, but it’s done! My only concern is that the “joker” valve is susceptible to damage from freezing as the weather changes.

Direct replacement on my Bayliner 285, very well made, highly recommend to watch the videos by Jabsco to save you time, now my toilet flushes and works again!

Absolutely love the lock system. This was easy to install. Great fix

Solved my head problems! I didnt realize the pump was so important. I went from having to pump about 10-20 times to get the flush water coming in, to only having to pump about 2-3 times. I shouldve replaced this piece on my boat long ago (my old pump was at least 10 years old).

worked great!
