Dometic 385310076 Pair of 🦆 Black 1-1/2" Duck Ball Valve Kits Review

I installed it a few weeks ago and so far so good. FYI: If you are restoring your vacuflush system you will need to order 2 sets of these.

1 1/2" is almost a "one size fits all" vacuum toilet and mine is no exception. Just two things to know will make sure you're heading in the right direction and make sure you replace all FOUR so you don't have to do it all over again.

Anyone who owns a vaccflush toilet system knows that these items need to be replaced on a regular basis. There's really no choice. But I wonder why they are so expensive for such a simple piece of rubber.

Work. My pump started to work intermittently so I originally bought their kit from another manufacturer and then it worked continuously. I bought them from Dometic and replaced other brands' platypuses and everything works great. They are of much better quality than usual.

After replacing both sets of duck valves I can go back to my toilet after a week of downtime and the suction is still there whereas before the pump was on every 1-2 minutes. My only complaint is that I didn't replace them sooner!

I didn't really bother with the main units on our boat until the outboard pump stopped working. Fortunately, it wasn't difficult to disassemble, and the bills inside were deformed and lost their shape. Luckily Dometic, in their wisdom, stamped the account number on the pump and of course you can find pretty much anything at Revain. The pump is now running like clockwork.
