Replacing a faulty valve ensures safe operation and protects your laundry area from unexpected flooding.
Tools & Materials You’ll Need

- Leak sensor (optional but recommended)
Washing Machine Shut Off Valve Replacement Guide
Follow these simple steps to handle your own washing machine shut off valve replacement:
1. Turn Off the Water Supply
Close both the hot and cold water valves that feed your washing machine. This prevents water from spilling out when you disconnect the hoses.
2. Disconnect Washer Hoses
Using your wrench, carefully unscrew both washing machine hoses from the existing valves. Have a towel ready to catch any remaining water in the hoses.
3. Install New Adapters
Thread new adapters onto the hot and cold shut-off valves to prepare them for the new piping.
4. Measure & Cut Pipe
Measure the distance between the adapters and the shut-off valve connections. Use your tubing cutter to cut plastic pipe sections to the appropriate length.
5. Assemble New Piping
Use PVC primer and cement to assemble the pipes and fittings, connecting everything securely from the adapters to the shut-off valve.

6. Prepare Automatic Shut-Off Valve (Optional)
If installing an automatic shut-off valve, thread adapters onto both hot and cold connections.
7. Mount the Shut-Off Valve
Hold the valve against the wall and mark the mounting holes. Drill holes and insert hollow-wall anchors, then attach the valve to the wall with screws.
8. Reconnect Washer Hoses
Attach the hot and cold water hoses to the new shut-off valve and ensure all connections are tight.
9. Add Leak Sensor (Recommended)
Place a leak sensor on the floor near the washer and connect it to the shut-off valve if using an automatic system.
10. Power Up
Plug your washing machine into the shut-off valve (if automatic), and then plug the valve into your wall outlet.
11. Test for Leaks
Slowly open the water supply valves and check all connections carefully for leaks. Tighten fittings as needed.
