I am putting 2 toilets back to back and a toilet and urinal back to back on a common wall over the solids side of a two compartment septic tank. Is it ok to plumb them direct down and if so is a vent stack necessary for proper flushing? firstname.lastname@example.org
I would say no because you have to have acess to tank, you would also have chance of fumes comming into bathroom if you would get a crack in tank. Check with your local Plubing Insp. If they OK it you will stll have to vent it, are you using carriers or building a floor on tank.
