Signs your laundry drain is clogged
- Water spills out of the standpipe behind the washer during the drain cycle
- The laundry sink fills up when the washer drains
- Water appears around a floor drain or the base of the washer
- A nearby tub, shower or toilet gurgles when the washer empties
- Suds or gray water come up through a nearby drain
- Musty or sour smells around the laundry area
Why laundry drains clog
Lint is the biggest factor. Every load sends fibers down the drain, and they mix with detergent residue and fabric softener to form a felt-like mat that narrows the pipe. Other causes include:
- Sand, dirt and pet hair from work clothes, beach towels and pet bedding
- Small items like socks, coins and hair ties that slip past the drum
- A standpipe that is too short or a drain line that is too small for a modern washer's pump
- A laundry line that shares a path with other fixtures and is affected by a clog further down
How we clean a laundry drain
Standpipe and trap
We pull the washer hose and inspect the standpipe and trap for lint mats and debris. A cable through the standpipe clears the trap and the line behind the wall.
Laundry sinks
Utility sinks often collect paint, grout, dirt and lint. We clear the trap and branch line and check that the sink and washer drain properly when used together.
Longer or older lines
Where a laundry line has heavy buildup along its length, a cable may only open a small path. Depending on the pipe, hydro jetting can clean it more completely.
When the washer reveals a main line problem
Because washers drain so much water at once, they are often the first appliance to expose a slow main line. If water comes up into a tub, shower or floor drain when the washer runs, the blockage may be past the laundry line. In that case clearing the standpipe will not stop the overflow; the building's main drain needs attention. If water is surfacing at a garage or laundry room drain, see floor drain cleaning.
Tips to keep laundry drains flowing
- Add a lint catcher or mesh filter to the end of the washer drain hose. Check it after every few loads, because a full filter can make the standpipe overflow on its own.
- Use the right amount of detergent; too much leaves residue in the pipes.
- Shake sand and dirt out of clothes and towels before washing.
- Check pockets for coins, tissues and other items.
- Do not let paint, grout or plaster go down the laundry sink.

Garage laundry in Wrigley and West Long Beach
In many homes in Wrigley and West Long Beach, the washer sits in the garage or on a converted service porch. Those laundry hookups were often added after the house was built, and the drain may run a long, nearly flat path to reach the main line, which gives lint more chances to settle.
Shared laundry rooms in apartment buildings take heavy use from several households, so their drains clog more often and an overflow can reach neighboring units. If you manage a building with a shared laundry room, scheduled drain maintenance can help avoid surprise overflows.
