LOML wants the washer/dryer moved to the basement. I already said it could be done but just learned today that the stand pipe needs to be 18" above the p-trap. I don't think I have those clearances
Here's the situation - septic exits the south wall of the house about 4' off the basement floor. Existing washer drain starts on north side and 2" line is run to septic. Plan was to move the washer downstairs and put it on the north wall more or less in line with the existing drain. Then bring the drain to the washer and hook in. But if the standpipe has to be 18" above the p-trap is this top or bottom of the trap? and does it matter where the trap is? at the end of the run where the drain ties into the septic it is a few inches below the bottom of the joists. So if I measure from the bottom of the trap to the top of the joist I may have 18" . The vent would be back at the original location - about 12' away if that matters.
