Step 1: Turn Off Water Supply

Locate the water shutoff valves beneath the sink or behind the bathtub and close them to prevent water from flowing.

Remove the handle with a flathead screwdriver. Behind the handle, you will find a retaining nut. Use an adjustable wrench to loosen and remove the nut.

Insert the new cartridge into the valve body and align the splines. Push the cartridge in until it seats firmly.

Step 6: Tighten the Retaining Nut

Use the adjustable wrench to tighten the retaining nut securely. Do not overtighten.

Step 7: Reinstall the Handle

Align the handle with the cartridge and slide it onto the stem. Secure the handle with the retaining screw.

Step 8: Turn On Water Supply

Slowly reopen the water shutoff valves and check for leaks. Tighten any connections if necessary.

Wear gloves to protect your hands.
If the cartridge is stuck, gently tap it with a hammer or use pliers to remove it.
Replace the cartridge regularly, typically every 5-10 years, to maintain optimal performance.
