Appreciate your advice, @DDW.
So, naturally, my new install of the Lavac requires modifying the mounting shelf that the old much-loathed Jabsco was bolted on to.
The new install requires the toilet bowl to be installed several inches more forward (toward edge of shelf, I.e., inboard ) in order to fit the pump behind the toilet. (See first pic).
Hoses will be routed basically as in my kindergarten CAD drawing (next pic), except that pump will be mounted behind and not beside (to right of) toilet. This was my first rough in of the toilet sketch. Red blob is the pump. Blue dot represents hole that 1 1/2” hose passes through into cabinetry, blue circle with line through it represents 1 1/2” ball valve/waste out.
My only question (I think...) has to do with the height of the pump. The install manual says, “Establish a position for the pump where the pump inlet is no lower than the bowl top.” I’m not 100% sure my pump is high enough. The bottom/inlet side of the the pump body is right at the top of bowl (and can’t easily be moved higher), while the inlet hose connection/barb fitting is *just below* the top of the bowl.
I know the the toilet works on a vacuum, I.e., in a different way from a basic Jabsco (say), so pump location/orientation is key, but I’m hoping in my case that it’s sufficiently high enough relative to bowl. (That pump and its hose run is pretty bulky in the head of a 33’er...I’m always looking for creative ways to justify to my wife the need to upsize to a 40’er )
