I am having a serious problem with my washing machine drain. First some background, I live in a 1 year old double-wide manufactured house. The washing machine drain is 1-1/2". The top of the drain is about 4' off the floor. The drain goes down about 28" before the "J" trap, then over about 6" and then a 90 degree. At the 90 degree a pipe goes down under the house and a pipe up for the vent which has a mechanical plumbing vent about 18" up.

Now here is my problem, I own a Maytag washer that's about 12 years old. The washer drain is backing up and coming out of the top of the stand drain pipe. The house manufacture has been here several times to try to fix my problem but as of yet nothing has help. The drain was first snaked, all clean. Then they put on a new mechanical plumbing vent, thinking it wasn't working right, didn't help. Then they went under the house and put in a new line going straight to the 3" and into the septic, no help. The manufacture says that it must be my washer putting out to much water at once but the washer has been in 3 other houses besides this one with no problems at all. I have asked them (many times) about the drain being 1-1/2" and not 2" and they keep telling that's not the problem. They also said that it could be my septic, something about a filter in the septic could get cloged if I use Charmin toilet paper. The gentleman that put in my septic says that it's not my septic because if it was it would backup other places in the house and not just the washing machine. Please help me!!


Thanks,

I think it is a problem to have a 1.5" drain pipe for a washer. Disconnect your 1.5" pipe from the 3" drain, run a load of clean water and let it drain. If it backs up you have isolated the problem to the 1.5" drain.

Bal nailed it. The newer Maytag washers have a stronger pump that puts out too much discharge for a 1 1/2" trap and standpipe to handle. We had a women that had the same problem as you. Maytag had to take back her washer and send her a different model. Good luck, Tom

Tom,

I got to reading some of your other post. I see that you use a compression fitting on your washing machine. Where can one get a compression fitting like that? Lowe's, Home Depot?? Can you use that with ABS pipe?

Thanks

Hey Scott,

The fitting's called a compression fitting, (see image). This will glue on the standpipe and compress on the hose. I've had one on my washer for years. Good luck, Tom
