DIY guideSump pump

Replace the sump pump's check valve

Unplug the pump, loosen the check valve's couplings, and fit a new valve with its arrow pointing up, the way the water leaves.

7 steps

Tap a step to watch it again.

On the pipe just above the pit, find the valve with a rubber coupling at each end and an arrow on its side.
Unplug the pump so it can't start while the pipe is open.
Dry hands. Hold the plug, not the cord.
Set a bucket under it and loosen the clamps at both ends. The water above it will drain out.
Work the old valve out of its couplings.
Push the new valve in with its arrow pointing up, the way the water leaves, and tighten both clamps snug.
Plug the pump in and pour water into the pit. Watch for drips; a soft thunk as it stops is the valve closing.
A cracked pipe or drips that won't stop: ask Handyman for a plumber, and keep an eye on the pit.
