The Dometic toilet in my RV has no separate flush wand. It flushes nicely with a ring of water injected below the rim. It lets you use a pint or so to flush #1 and as much as you need for #2. It has a secure ball valve at the bottom that blocks any odors. It does need to be mounted so it is a straight shot downward to the holding tank and it may be a problem when bouncing around in a seaway with an almost full tank.


I think PVC is fine for drains, but I would try to only use it above the water line and transition to hose when it is necessary to go lower in the bilge. It is subject to cracking under vibration and below the water line could be a disaster.


PEX is fine for fresh water plumbing- either with the screw on compression type fittings or the mechanical clamp ones.
