Washing machine drain backing up

Signs your washer drain is clogged

If the washer pumps out but the water has nowhere to go, the clog is in the drain, not the machine. Until we get there, don't start another load.

• Water spills out of the standpipe
• The washer stops with water left in it
• Nearby sinks gurgle during the drain cycle
• A musty smell in the laundry room
• Water comes up in a floor drain or tub
• It only overflows on large loads

How we clear a washing machine drain

Washer drains carry a lot of water fast, so the whole line has to be clear, not just the top of it. Worth reading first: what a washing machine does to a septic system.

Check the hose and standpipe

We check the drain hose, how far it goes into the standpipe, and whether the standpipe is tall and wide enough.

Clear the washer drain line

A cable clears lint and debris from the standpipe trap and the line it runs to.

Jet a line full of lint

Lint and detergent build a lining that a cable only cuts through. Jetting cleans the pipe back to full size.

Run a full washer drain cycle

We run the washer's drain cycle and watch the standpipe before we leave.

Why washer drains back up in Shore homes

Laundry drains slow down over years, then overflow all at once.

Lint and detergent

Lint sticks to detergent residue inside the pipe and narrows it a little with every load.

Lint on septic

Lint doesn't break down in a septic tank and can reach the drain field. A lint filter on the washer drain protects the line and the septic system.

Older laundry rooms

Standpipes in older homes are often too short or too narrow for modern washers, which pump water out faster.
