Laundry room drain question
Author: Ryan (CA) Can anybody tell me if this plumbing is adequate for the drain water to flow from the washer? I have added the 90 to go to the drain. Is this also up to code? I am in California. I am learning as I go so any help would be appreciated. Thank you very much! Edited 1 times.

Thanks for the response
Author: Ryan (CA) Thanks for the response. I didn't want to change too much because I was adding the washer outlet box and I wanted the lines to be just above the water lines. Edited 1 times.

Author: North Carolina Plumber (NC) I would be concerned about splash back when the water hits that 90. I would have used 2 45s.

Author: stuckinlodi (MO) splashback is a possibility, washing machines nowadays can put out something like 15-20 gallons per minute, maybe more on some models.

Re: Laundry room drain question
Author: stuckinlodi (MO) Is that 30" spec the min height from floor to top of standpipe, or from the trap to the top of the standpipe? In this case the top of the standpipe may be 30" from the floor, but by having the trap above the floor and having the standpipe bent with elbows that may reduce the effectiveness of the standpipe over what a straight 30" standpipe would give.
