Forum Title: Overflowing Laundry Drain
Hi, I have an older home with a 1.5" laundry drain that frequently overflows. I'm pretty sure the drain itself is fine- it's just not equipped to handle the flow pumped out of today's washers. The drain is conveniently located near a bathtub and a kitchen sink drain. I had a (probably bad) idea to tie the laundry drain into one or both of these drains to expand the laundry drain's capacity. I would also expand the washer standpipe to 2" or 3". I thought with this setup I might be able to avoid digging up the floor to perform a proper expansion. Could this work? Would it in any way be able to hold up to code? Other suggestions welcome. Thanks! Cody

pull the washers flex hose out of the stand pipe, using a tape measure, slowly, feed the tape down the pipe till it hits the fitting. you will be able, to feel if the fitting is a 90 or a ptrap by the amount of resistance on thhe tape measure old country boy trick

Thank you for the suggestion. Unfortunately my utility room has no space for a laundry tub. I pulled back some more of the drywall today and saw that the standpipe goes straight down into the foundation, leaving me a little puzzled as to where the trap and vent may be (if they do exist at all). Think I may just call a plumber to get sorted...

I think a laundry tub installed to accept the flow will get you away from having to go to a 2in drain (grandfathering).
