Hey guys, first post on these boards but have been viewing them for months now, lots of smart minds and great stuff in here. I'm a (soon to be licensed) civil engineer so have a little more than half a brain, and have studied plumbing code for several hours now. The attached is what I plan on installing in the basement sub-slab here in a few weeks, and my only remaining question is installing a cleanout for the 2" run between the LAV and shower. The shower p-trap won't be accessible so no can do for a cleanout in NY plumbing code. Question is - can I install a 2" PVC test tee just upstream of the san-tee for the sink (within the sink cabinet) and satisfy a cleanout for the line? The WC does satisfy for a cleanout here in NY so the 3" is fine, the removable p-trap for the 2" section downstream of the LAV is acceptable, and wet venting to AAV's is also approved. Do you guys also see anything else wrong with this setup before I start breaking concrete? Thanks all - I do plan on contributing regularly on these boards now and have a bit of knowledge to share!
