How To Fix A Leaky Bathtub Faucet Moen

If you have a Moen bathtub faucet that is constantly dripping from the spout, you may be wondering what to do. Leaks are not only annoying, but they can also lead to wasted water and a higher water bill. Fortunately, fixing a Moen bathtub faucet leak is not difficult, and you can do it yourself with a few basic tools. Here is a step-by-step guide to help you fix your leaky Moen bathtub faucet.

Step 1: Turn Off Water Supply

The first thing you need to do before you begin to fix your bathtub faucet is to turn off the water supply. Look for the shut-off valves under the sink or behind the bathtub, and turn them off. You may need to turn off the main water supply if you cannot find the shut-off valves.

Step 2: Remove Faucet Handle

Next, you need to remove the faucet handle. The handle may be held in place by a set screw located under a decorative cap. Remove the cap using a flathead screwdriver or a knife, then use an Allen wrench or a Phillips head screwdriver to remove the set screw. Once the set screw is removed, you can lift off the handle.

Step 3: Remove Cartridge

After removing the handle, you need to remove the cartridge. The cartridge is the part of the faucet that controls the flow of water. To remove the cartridge, you need to unscrew the retaining clip or nut that holds it in place, then pull the cartridge straight out. If the cartridge is stuck, you can use a cartridge puller to help remove it.

Step 4: Inspect Cartridge

Once you have removed the cartridge, you need to inspect it for any damage. Look for cracks, worn out washers, or worn-out O-rings. If you find any damage, you will need to replace the cartridge to fix the leak.

Step 5: Replace Cartridge

To replace the cartridge, you need to insert the new cartridge into the faucet body. Make sure to align the pins on the cartridge with the holes in the faucet body. Screw the retaining clip or nut back into place, making sure to tighten it firmly.

Step 6: Reassemble Faucet

Once you have replaced the cartridge, you need to reassemble the faucet. Reattach the handle and the set screw, then snap the decorative cap back into place.

Step 7: Turn On Water Supply

Finally, you need to turn on the water supply. Turn on the shut-off valves or the main water supply and test your faucet for any leaks. If your faucet is still leaking, you may need to repeat the above steps or call a plumber for further assistance.
