Jabsco Manual Pump Assembly f/29090-Series

After a little shopping around there was only $1.00 difference between a rebuild kit for the older style pump and a complete new model pump...no brainer! This was an easy installation updating an 1999 model head, four screws and four hose clamps. The only way it could be simpler is if they sent someone to install it for you.

Install time was less than 5 minutes. The new locking feature is well worth the price of pump replacement and works great. No more holding tank backing up into the bowl. When compared with the price of replacing the various gaskets and seals to rebuild your existing pump, this is a no brainer. Get it now. July 2011 update: Seems the seals on this work no better than previous models. After 2 years I again have the holding tank backing up into to the bowl. So, I replaced the joker valve and the bottom flapper at a cost of $36. For just a few $$ more I could have replace the entire pump and had all new seals and O-rings. My advice is to just plan on replacing the the pump every 2 years since it is less expensive to do that than to replace all the seals. Too bad Jabsco couldnt create a product that truly locks. May 2014: Installed a new one in the spring of 2013. Lasted one year and just replaced the joker valve in spring of 2014. The cost of these has gone up considerably and seal last a year, maybe. Going to replace the toilet with something other than Jabsco.

Works but seal leaks from handle when operated

I have a 1998 REGAL Commodore 258 with a Manual Toilet Model 29090-0000. The unit is plumbed through a saltwater seacock and is above the water line. The toilet is about 8-10 feet from the seacock. The problem was that the pump handle would not go up and down ... possible corrosion issues. Get some old towels out to absorb any liquids that might seep out. The first thing I did was unscrew the 6 screws holding the pump to the base (4) and elbo (2). They came right out. I used a long craftsman 12 screw driver. Thanks to a tip I read on another review. The unit comes with 2 important rubber seal/checkvalve type gaskets. No other parts were needed. The second thing I did was with an electric screwdriver loosened the stainless steel clamps. Third was disconnecting the existing hoses from the pump. Since the pump was now movable, is was easier to get the hoses in a position to twist and pull them off. Once the old pump was set aside, I poured 1 liter of water down the toilet water source input hose that is connected to the seacock to make sure there was a clear path to the bottom of the boat. The boat was up on a lift. Water flowed out at a steady rate. Next reconnect everything, and pour 2 liters into toilet bowl for a prime. Lowered boat into the saltwater, pumped about 6-8 times and water began filling in the bowl. Ran about 4-5 gallons through the system checking for leaks. Works great. Nice to have a functioning head!

I have rebuilt several these in the past. I never will again. The cost differential isnt significant enough for me. This came on time, undamaged and I was able to use credit card points meaning it essentially cost me nothing. Ive never been disappointed with any Jabsco product Ive used. Recommendation without reservation.

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

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

I ordered this replacement assembly to help a friend who was a little boater impaired; Although it was tempting to go ahead and buy a whole new replacement toilet (at a little over twice the price), we decided that because everything else on his head was fine, it wold be simpler, less expensive, and better to just replace the leaking pump. Was a quick repair and made his head like new. Since this assembly contains almost all of the working components of the head, I recommend it highly, and you do not have to go through the messy part if you replace the entire head!

Got a pit of these on sale- saved me from a slowly seeping head that got pretty nasty and one that randomly hydrolocked and tried to shoot poo water in your face. Very easy remove and replace install. The swivel nozzle for the poo hose makes it a cinch. Make sure you tighten her down all the way.

What a life saver. I found this at a marine store for twice the cost. I purchased this kit, which saved me quite a bit of money on a toilet replacement. Its well constructed and reasonably priced.
