Drain for washer machine backs up

How old is the home? You either have a partial cliff or deteriorated drain lines

I'd run a snake down the drain pipe first thing. Assuming at one point in time it flowed fast enough to not spill over. Sounds partially clogged.

You might be surprised at the amount of fibers that get washed out of each load depending on what is being washed. The tend to build up at joints in the pvc because of the sharp edges were sections are welded together.

How do I restrict the flow?

Partial clog that my phone keeps auto correcting to partial cliff. If I was a betting man I bet that you have cast iron drain lines that are rusting out

I had this problem 2 years ago. House built in the 40s still had a grey water line running somewhere in the back yard (never found exactly where the pipe went) the rest of the old cast iron plumbing had been redone with PEX but not the washing machine drain and kitchen sink for some reason and that line had partially collapsed. The plumber just went under the house cut the cast iron out and tied those pipes in with the newer plumbing

Sounds like partial blockage on your main line.

If you can't make the turn wiht your snake, have a plumber do it. He can evaluate your situation.

A washing machine dumbs alot of water all at once.

The vent can also get plugged causing slow drainage. This can be flushed out from the roof by running your hose down it with a fixed brass blast nozzle

Sometimes the washer drain and kitchen sink share a line and the sink can create a grease clog.

I called a plumber. He’ll be over Monday morning. I did what I could, but no success.

I tried running a snake, but the pipe makes this u shape at the bottom. I can’t get the snake to bend that way.

no, you dont snake the drain pipe, you cant get passed the p-trap and then the tee or 90 after it

there should be a clean out plug outside on the opposite side of the house from the main sewer cleanout. usually on the opposite side of the wall for the washer, there will be a waste water line for the laundry and most likely kitchen area as well and thats where you snake it.

what happens is food getting washed down the kitchen sink settles right where the pipe connects to the main waste water line and it builds up and gets solid until it blocks off too much of the line to let the washer drain and it backs up
