Hi all! Any input you could provide to our dilemma would be GREATLY appreciated:
We bought an "upflush" toilet for the basement (www.saniflo.com - the saniPRO unit), which uses a maceator and a pump to pump waste up to a standard drain line (in my case the kitchen sink line that runs across my basement wall). It sits on the basement floor. No digging required. It has inputs on each side to connect a shower and sink, and it'll pump that water up, too.
Ceiling is 7 foot in the basement. Code says shower must be 6'8" to be legal. I can't fit a ptrap and have enough fall to get the water from the shower to the pump in the 4" that i have to spare.
Question 1: Can I not use a ptrap? (The pump is between the shower drain and the sewer line - think the pump might be enough to block the gases from coming up the shower drain?) I know CODE says I need one, but let's pretend that doesn't exist for the sake of discussion.
Question 2: Are there any alternatives to a p-trap? Are there low profile p-traps or valves that will fit in the line and stop the gasses? What about the ProSet "Trap Guard"? Think I could make something like that work? (http://www.trapguard.com/index.htm)
Question 3: Any idea how I can make this work in 4 inches?
Saniflow says I can NOT break up concrete to allow room for the ptrap because it wont allow enough fall from the shower drain to the pump. But their own instruction booklet says 1/4 inch per foot, and it only has to go 4 feet to the pump.
Thank you! Thank you! Thank you! Thank you! Thank you! Thank you!
Any input you have is greatly appreciated!!
