SaniCompact upflush toilet- no venting
it say it must have 3 feet of 1 inch pipe before dumping into a 3 inch drain and i would not hook the sink to the unit since there is a way to drain sink which would let the unit run less. i have installed lift toilets and i only recommend them if sewer main is above slab, due to cost of unit noise of unit and maintenance. it is cheaper to remove a little concrete and better in the long run
be careful my advice only comes from general knowledge i know about the 4 rules it takes to plumb and they are
1 poop needs to flow down hill. 2 hot on left cold on right
3 i get a pay check on Mondays 4 do not chew finger nails at or after work.
