Hello all,
I’m a DIY’er who’s installing a garage urinal and hoping to get some advice on teeing into the main septic line in my detached garage. Per the specs on the urinal, I need to have the drain outlet at 12 1/4” from the ground for an ADA set up and 19 1/4” from the ground for a “standard” set up. I’m not a tall person so I was hoping to keep it around 20” or so.
Anyway, the main septic pipe I’d like to tie into is a 2” horizontal ABS pipe within the wall. The problem is the pipe is already 21” off the ground and I can’t modify it’s height further down as there isn’t any room to maintain the appropriate slope for drainage before it hits the concrete of the foundation.
A combo wye attached to a male adaptor placed horizontally would keep an acceptable height, but it protrudes from the wall by a significant margin. A vertical sanitary tee with the adaptor maintains appropriate depth, but is too high. I’d love to use a horizontal sanitary tee, but read this is against code, but not sure why.
This is a Toto unit that uses only 1/8 gallon per flush, so this thing won’t see large volume or any solid waste obviously. Any thoughts on making this work? Worst case scenario I put a step stool in front of it, but I’m really trying to avoid it.
