When your Delta faucet begins to leak, there is a simple and effective way to repair it. It involves removing the cartridge inside the faucet and replacing it with a brand-new one. This task is something the average person can accomplish without much difficulty, and it does not require a plumber. You will need to use a wrench and a pair of pliers, however. After this repair, your faucet will no longer leak and should perform like new.
Instructions
1. Turn off the water by shutting off both the hot and cold water pipe valves under the bathroom sink.
2. Remove the small plastic cap on the top of the Delta faucet handle with your knife. Underneath is a small set screw. Loosen the set screw with a screwdriver or Allen wrench (if it is an Allen-head screw) and then slide off the handle.
3. Place the edge of a screwdriver on the plastic washer, which should now be visible on top of the faucet, and nudge it to the right to loosen it. You can also grasp the washer with a pair of pliers and turn it.
4. Lay a soft cloth over the top of the dome nut (the rounded piece on top of the faucet head), grasp it with the larger set of pliers and turn it left to loosen and remove it.
5. Remove the ball valve assembly (the cartridge) and then take out the small round seat springs in the base of the faucet. Replace these with new seat springs and then install a new ball valve assembly.
6. Replace the dome nut and tighten it by hand. Next, install the washer over the dome cap and screw it in place. Tighten this securely on the dome nut to hold the assembly together.
