I'll try to make this simple. I have a septic system and the main line goes out about 5ft above the basement floor.
I am planning on installing a bathroom in the basement. As such, I've decided on a Saniflo Sanicompact macerating toilet that requires no venting, and discharges into a 1" pipe. I have a location right above the toilet that is 4" pipe which i can easily tie into...so I think that is solved.
But to use this non-venting unit, I cant tie the sink and shower into it. So, I plan running pvc drain line from the sink and shower about 12 ft away into a pre-existing crock which is emptied by a sub-pump. The crock is there for our washing machine and laundry tub.
Can I tie these two lines together on their way to the crock? Ideally, I'd like to also tie in a kitchen sink drain which drops in from above too. So there'd be a kitchen sink drain from above, tee'd into a basement level sink drain pipe which would be tied into the shower drain....in that order....then on to the crock. The entire run would be about 15 feet with 1 90 and 2 45's. IF this is possible, what size pipes should I be using? Is there a certain layout/setup that would make this work?
Also, when emptying into a crock like this, does the shower and sink(s) need to be vented? Separately, or individually? If so, can the vent exit my basement horizontally, above grade?
Thanks for the anticipated help.
