I wonder how hard it would, assuming there's enough room, to tee in a trap
under the toilet for diverting to a city sewer. Could just place a flapper
valve to either fill the tank, or go directly to the CIty sewer, by-passing
the tank. Then there would be two dump valves one for city hookup
and one for draining the tank. If a trap were provided, then the methane
wouldn't get achance to draft back into the trailer.
Just a thought. Might be worth thinking about when re-habing a coach. bobb |
