Perfect. Thank you!The toilet model is Sealand Dometic 964. If you have the pump-out model it is 964MSD. It's the same toilet, it just has the fittings on the back. Those latches used to be available by themselves but now I find they are only available in a rebuild kit.
The part number for that latch is 310067. When you look up that number it should show the kit.
Yes, they had 3 different setups. A carry-out porta potti....then there is the. same pot, with a deck pump-out....Then there was one with the same pot but with both deck pump-out and macerator with a Y valve for overboard discharge.Did the 228 ever come with a macerator pump?
