A more modern method is to use two discharge outlets in the holding tank..

One hooked direct to the deck fitting the other to the lectra san or direct to overboard discharge.

AS almost all the poop pump problems I have had come from the unit drying out and paper holding the suction valve open just a tiny bit , I would have a tank built with a bottom drain hookup .

A Dupree valve would allow the tank to be closed and the pump removed if required.

Requires disassembly and reuse of valve gate,end cap, o-rings, spring, ... The Twis-Loc termination system provides a truly durable sewer hose connection.
