Situation:
Boat is currently equipped with a manual Jabsco toilet.
The seawater inlet is 3/4" (19mm).
The waste water outlet hose is 1 1/2" (38mm) and connects to a waste tank.
Plan:
1. The new electric bowl has a 3/4" (19mm) seawater inlet at the top and a hose is provided as part of the package. So I'll connect that hose there and to the ParMax water pump on the other end.
2. The ParMax water pump needs adaptors to connect the 3/4" (19mm) hose because it has no connectors at all. The package includes a straight and an angled connector. So I'll be using the already existing hose coming from the sea water valve, use one of the provided adaptors, connect it to the ParMax pump, use the second adaptor on the outlet side of the pump and connect it to the provided hose going to the bowl.
Problems:
1. The package contains a strainer. This has a 3/4" (19mm) inlet but no outlet connector. An adaptor is needed, but I have already used up both of them for the ParMax pump. Am I supposed to plug the strainer inlet directly to the ParMax pump without a piece of hose between?
2. Waste water outlet: The toilet bowl has an outlet on the incinerator with an outer diameter of 1" (25mm). So my existing waste hose with 1 1/2" (35mm) doesn't fit. There's some sort of adaptor in the package which goes to 1 1/2" (35mm) but the input is 22mm (I don't know what that would be in inches!). If this is meant to be used, I don't know how. Even if I had a piece 1" (25mm) hose to install it, it still wouldn't work because it's only 22mm on the input side.
What parts do I need to buy to make this work without making it a hack?
