How To Repair a Leaky Bathtub Faucet Single Handle Moen Fa

When your bathtub faucet starts leaking, it can be a frustrating and annoying problem. A leaky faucet can waste water, increase your water bill, and even damage your bathroom if left unrepaired. If you have a Moen Fa single-handle bathtub faucet, there are a few simple steps you can take to repair the leak yourself.

Tools and Materials You'll Need:

Phillips head screwdriver
Adjustable wrench
New O-rings (if necessary)
Plumber's grease

Step-by-Step Instructions:

Turn off the water supply. There should be two shut-off valves under the sink. Turn both valves clockwise to turn off the water supply to the faucet.
Remove the handle. Using a Phillips head screwdriver, remove the screw that holds the handle in place. Pull the handle straight up to remove it.
Remove the cartridge. Use an adjustable wrench to loosen the nut that holds the cartridge in place. Once the nut is loose, pull the cartridge straight out.
Inspect the O-rings. The O-rings are small rubber gaskets that create a seal between the cartridge and the faucet body. If the O-rings are worn or damaged, they will need to be replaced.
Apply plumber's grease. Apply a small amount of plumber's grease to the O-rings and the threads of the cartridge.
Reinstall the cartridge. Insert the cartridge back into the faucet body and tighten the nut until it is snug.
Reinstall the handle. Push the handle back onto the stem and tighten the screw.
Turn on the water supply. Slowly turn on the shut-off valves to turn on the water supply to the faucet. Check for any leaks.

If you have followed these steps and the faucet is still leaking, there may be a more serious problem that requires the assistance of a professional plumber.
