Change your Delta faucet cartridge.

Delta makes several different cartridge styles; the 1300, 1400 and 1700 series are the most popular. The 1300 is a basic on-and-off cartridge and the 1400 series offers a temperature-limit control. Then 1700 series Delta faucet cartridge is dual control, one for temperature and the other for water volume. Replacing Delta cartridges yourself will save a hefty service call payment and money on your utility bill as well.


Step 1

Close the water shut-off valves on the pipes serving the faucet. If you can't gain access to them, turn off the main water shut-off valve for the house or, if necessary, the outside water main. Turn on the faucet to release any water pressure still in the system.

Step 2

Remove the faucet handle. Levered faucet handles will have a setscrew under the lever. Handles with round knobs will have a screw located under an index button.


Step 3

Slide off the cartridge escutcheon by hand. The escutcheon is the long metal sleeve that covers the cartridge housing.

Step 4

Unscrew the Delta cartridge-retaining ring from the faucet body. Do this with your slip-joint pliers.


Step 5

Pull the Delta cartridge from the faucet by hand. If the cartridge is difficult to remove, gently pry it out of the faucet body with the screwdriver.

Step 6

Insert the Delta cartridge into the faucet by lining up the guides on the cartridge and the faucet body.


Step 7

Screw the retaining nut back on the faucet by hand and then tighten one quarter-turn with the pliers.

Step 8

Slide the escutcheon back on the faucet body.

Step 9

Replace the handle and secure with the screwdriver.

Step 10

Turn the water back on at the shut-off valves.


When you are removing the retaining nut, only use the pliers in the outer edge of the nut. This will keep you from deforming the nut.


Replace the Delta cartridge with the exact model you are replacing.
