How to Repair a Faucet Valve Cartridge
If you have a sink or tub with a leaky faucet valve cartridge, you will be pleased to know that this is a simple DIY project that you can do yourself. Repairing a faucet valve cartridge is not difficult and can be completed in an hour or less. To make the task even easier, here is a simple step-by-step guide that will walk you through the process. Let's get started:
Step 1 - Turn Off the Water
First, shut off the water to the sink or tub where you will be repairing the faucet valve cartridges. Do this by closing the water inlet valve to the tub or sink where you'll be making the repairs. To close the valve turn the valve clockwise.
Step 2 - Drain the Faucets
Open the faucet handles all the way to drain any water that may be left in the faucet pipe or water supply line.
Step 3 - Remove the Handle
To remove the handle on the faucet, use a flat head screwdriver to gently pry off the plastic cap that covers the retaining screw. Then, use a screwdriver to remove the retaining screw and remove the handle.
Step 4 - Remove the Lock Ring
Many faucet valve cartridges have a lock ring that secures the cartridge in place. To remove this lock ring, you will need to use a screwdriver or a pair of pliers. Use the appropriate tool and remove the lock ring.
Step 5 - Remove the Faucet Cartridge
Once you remove the lock ring, you should be able to simply pull the faucet cartridge out of the wall or fixture. Remove the old faucet cartridge and set it aside.
Step 6 - Install the New Cartridge
Slide the new faucet cartridge in to the slot where the old one was located. Make sure that the cartridge is inserted fully and that it snaps or settles into place.
Step 7 - Re-Attach Lock Ring
Reattach the lock Ring to the cartridge on the faucet.
Step 8 - Re-Install Handle
Replace the handle on the faucet and then tighten the retaining screw with a screwdriver. Place the retaining screw cover cap back on the faucet handle and snap it into place.
Step 9 - Repeat for Other Faucet
If you need to make repairs on the other faucet, repeat the process to remove the handle and lock ring and replace the leaky faucet cartridge.
Step 10 - Turn Water On and Look for Leaks
Once you have replaced the leaky faucet valve cartridges, you can turn the water supply inlet valve back on to resume the flow of water to the sink or tub. After you turn on the water, make sure to check the new faucet cartridge and inspect them for leaks. If there are leaks present, it is probably because the cartridges were not properly inserted into the slots. Therefore, if you notice leaks, repeat the process and re-seat the valve cartridges.
