Toilet Install

[John316]

I won't do the straight down shot because of the proverbial pile of poo which can block off the end of the pipe if not emptied in time. Just a thought.

Dave does have a point. Our tank is 150 gallons and we move quite a bit. There is no fear that that "stacking up." That is certainly something to keep in mind.

I have used a straight line from toilet to tank in all my busses since 1990 or so. I use flexible joints in the line in case of movement.  Occasionally have to spray inside it with the wand thingie...

We had a straight drop on our 4104 bus with 16 years and 150,000+ miles.  On our Freightliner conversion we have a straight drop and 12 years and 126,000+ miles, never a problem.

We do have means to "back-flush" the black tank with the grey water.  The procedure is;
(1) dump the black tank,
(2) leave black tank valve open, shut the main discharge valve and then open the grey tank valve to "back-flush" the black tank,
(3) close the grey tank valve and open the main discharge valve to dump the back-flush from the black tank,
(4) close black tank valve and drain grey tank.

A very simple operation once you get used to it and never a problem with sewage in 28 years!

Just the way we do it!

Simpler yet is one tank, just dump and go. Flushing is automatic with grey water in the tank.

Fresh water flushing is a waste of time.

Gus I would agree!
