i am installing a washer and dryer and have a few questions. The easy one is the typical height of the drain box (top of open pipe). My second issue is more frustrating for me. I have two drain lines to connect to. One is a cast pipe but it is 3 feet off the ground. The other option is a pvc pipe that goes out the side wall at ground level... only issue is it is 1 1/2' inch not 2 ". The thought of tapping into a pipe so high scares me and i can't figure out how i pull off a trap. The 1 1/2" pipe was used by the previous owner and is a dedicated line to the septic tank buat all i read says it is too small. Btw, there is no venting issue with either... i will tie into a 3" pipe going directly to the roof. Thanks for opinions on the best of two evils.
