A Delta 1500 series faucet uses what is called an inner cartridge valve as a control mechanism. This part makes the hot and cold water run when the handle is turned. If your faucet is leaking around the stem or handle, it is likely that this part needs to be replaced. Completing this replacement requires few skills and only simple tools, but it will require about a half hour of your time.
- Skill level:
- Moderately Easy
Things you need
- Allen wrench
- Channel locking pliers
- New 1500 Series cartridge and seals
Turn off the water by closing the water valves.
Remove the screw on the top or front side of the handle with an Allen wrench. The 1500 Series uses Allen-head screws in all of its models. Slide the handle off the cartridge.
Loosen the dome cap by turning it slightly with channel locking pliers, and then unscrewing it by hand. Lift out the cartridge by pulling it straight up once the dome cap is removed.
Pull out the seals inside the faucet head by sliding the tip of the Allen wrench inside, tilting it to one side and pulling up.
Install new seals inside the faucet head by pressing them into place with a finger. Next, replace the cartridge by pushing it inside the fixture.
Place the dome cap back on and tighten it, first by hand and then with the channel locking pliers. Slide the handle back on the stem and install the retaining nut. Tighten the retaining nut with the Allen wrench.
