Does a washing machine require a trap?
If they omit the trap and vent, it’s a mistake that can cause problems on two counts. The lack of a P-trap exposes the area to sewer fumes and the lack of venting will cause the drain to run sluggishly and overflow. Washers, like all fixtures, need a trap.
How do you clean a washing machine trap?
- If the screen is removable, soak it in hot water for 10 minutes to clear away residue.
- If the filter is secured in place, clean lint from it with a soft brush or paper towel.
- If the trap is disposable, replace it when it becomes clogged.
How do you hook up a washing machine trap?
The first solution is hooking the washing machine hose into the top of a standpipe with a P-trap at the bottom. Then, once attached to the P-trap, run the pipe through the outside wall. This can then be attached to a hopper head or gully. An alternative is attaching the pipe directly into a soil stack.
