Jabsco Manual Pump Assembly f/29090-Series

I needed to replace my Jabsco pump. It was leaking around the top and the plunger was getting very difficult to work. I read the comments from customers and noted the one about the bottom connection was at a 45 degree angle up and theirs was 45 degrees to the left. I totally agree with this. All other connections were exactly the same. So I took off the connection and gasket from the new pump cleaned up the old one that was angled correctly and simply use the old one to make the connection to the line going to the tank. It worked great. So consider this as an option. Tks again to Amazon for this product.

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!

Perfect replacement pump four our toilet in our boat. Very easy to install. One thing to be aware of... it did not come with a joker valve installed in the output fitting. I didnt know this until after installing the pump when I noticed I was getting back fill from the holding tank. I guess you have to buy this separately, which I did and now all works fine.

We bought our boat used and had no idea how and when our head had been maintained. So when we had backflow and leaking, we replaced the entire assembly kit. It now works PERFECTLY! The price on Amazon was way better than West Marine, so it was worth the wait. Just wish we had bought the deal with the macerator pump...ours died about 3 weeks later!

Original equipment replacement

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).

It took me about 1 hour to replace it, not the best hour in my live as space is very very tight and, well, you know. But I got it in and it works perfectly. I was very happy to see it fits perfectly in my 1990 original head.

Easy update to improve your Jabsco manual toilet. Be sure to pump out first to keep things clean and have paper towels and sanitizer on hand. Wear nitrile gloves. Otherwise an easy job. Not worthwhile to replace only gaskets to save a few $$. Loosen the end nozzle and dont tighten the clamps on the hose that attaches to it until youve tightened the four Phillips screws that secures the pump first. The nozzle rotates slightly which assures an airtight fit. Secure nozzle and hose clamps last.

It does exactly what its supposed to do...cant ask for more!

Replacement for old assembly .....installed easily and worked great.
