How to Replace a Washing Machine Shut Off Valve
I’ll never forget the day my washing machine decided to take a bath in my laundry room. I was out running errands when it happened, and by the time I got home, the water had already seeped into the kitchen and hallway. The culprit? A faulty washing machine shut-off valve.
Replacing a washing machine shut-off valve is a relatively simple plumbing repair that even a novice DIYer can handle. In this article, I’ll walk you through the step-by-step process on how to replace a washing machine shut off valve, so you can avoid a similar watery disaster.
What is a Washing Machine Shut Off Valve?
A washing machine shut-off valve is a plumbing fixture that allows you to turn off the water supply to your washing machine. It’s typically located behind the machine, near the hot and cold water supply lines. The shut-off valve is used to isolate the washing machine from the water supply when repairs or maintenance are needed, or in the event of a leak.
Types of Washing Machine Shut Off Valves
There are two main types of washing machine shut-off valves: quarter-turn valves and gate valves.
- Quarter-turn valves are the most common type of shut-off valve. They have a lever that you turn 90 degrees to open or close the valve.
- Gate valves have a handle that you turn to open or close the valve. Gate valves are less common than quarter-turn valves, but they are more durable and can handle higher water pressure.
How to Replace a Washing Machine Shut Off Valve
Tools and Materials:
- Adjustable wrench
- Plumber’s putty
- New washing machine shut-off valve
- Bucket or bowl
- Rags
Step 1: Turn Off the Water Supply
Before you start working on the shut-off valve, you need to turn off the water supply to your washing machine. To do this, locate the main water shut-off valve for your home and turn it to the “off” position. Once the water supply is turned off, open the washing machine’s hot and cold water faucets to release any residual water in the lines.
Step 2: Disconnect the Water Supply Lines
Using an adjustable wrench, carefully loosen the nuts that connect the water supply lines to the washing machine shut-off valve. Be careful not to overtighten the nuts, as this could damage the valve or the water supply lines.
Step 3: Remove the Old Shut-Off Valve
Once the water supply lines are disconnected, you can remove the old shut-off valve. To do this, use an adjustable wrench to loosen the nuts that hold the valve in place. Be careful not to drop the valve, as it could damage the floor or your plumbing.
Step 4: Install the New Shut-Off Valve
Apply a bead of plumber’s putty to the threads of the new shut-off valve. Then, screw the valve into the water supply line by hand until it’s snug. Use an adjustable wrench to tighten the valve, but be careful not to overtighten it.
Step 5: Reconnect the Water Supply Lines
Reconnect the water supply lines to the new shut-off valve. Hand-tighten the nuts, then use an adjustable wrench to tighten them further. Be sure to tighten the nuts evenly to avoid leaks.
Step 6: Turn on the Water Supply
Turn on the main water shut-off valve to your home. Then, open the hot and cold water faucets on your washing machine to check for leaks. If there are any leaks, tighten the nuts on the water supply lines further.
Tips for Replacing a Washing Machine Shut Off Valve
Here are a few tips to help you replace a washing machine shut-off valve safely and efficiently:
- If you’re not comfortable working with plumbing, it’s best to call a licensed plumber to replace the shut-off valve for you.
- Before you start working on the valve, make sure to turn off the water supply to your washing machine.
- Be careful not to overtighten the nuts on the water supply lines or the shut-off valve, as this could damage the valve or the lines.
