I have a 2" drain line and 1/2" water supply installed in a wall capped for a future washing machine connection. Is the proposed piping in the attached photo correct and should a clean out be added before sanitary tee?
you want the clean out above the washer, so if the washer is full of water, you do not have to move it to unstop the drain
also studor vent has to be above the washer.
ptrap needs to be as low to the floor as possible
stand pipe no longer than 24''
