How do I Repair a Leaking Shower With a Cole Single Lever Cartridge?


A leaky shower faucet can waste water and energy. To repair a leaking Cole brand shower faucet, use a Bradley/Cole replacement single lever cartridge or an original Bradley repair kit because Bradley is the original equipment manufacturer (or OEM) of the Cole private label.

Things You'll Need

  • Flat-head screwdriver
  • Phillips-head screwdriver
  • Adjustable wrench
  • Channel-type pliers
  • Bradley/Cole replacement single lever cartridge
  • Pry off the cover plate on the handle with a flat-head screwdriver.

  • Unscrew the screw in the center of the handle and remove the handle and escutcheon (wall cover plate).

  • Turn off the water supply at the built-in shutoff valves inside the fixture using a screwdriver.

  • Unscrew and remove the bonnet nut or retaining ring with an adjustable wrench.

  • Remove the cartridge assembly. Simply grasp the end of the valve with channel-type pliers and pull gently.

  • Rinse the inside of the valve body with clean water to remove any debris.

  • Push the new cartridge into the valve. Be sure to align it in the same direction as the previous cartridge so hot and cold controls are on the correct sides.

  • Replace the bonnet nut and tighten with an adjustable wrench.

  • Turn water back on at the built-in shut-off valves and reattach the escutcheon plate and handle.

Tips & Warnings

  • Bring the old valve into the hardware store to make sure you are getting the correct part.
  • DANCO produces a Bradley/Cole single lever cartridge replacement, part number 80461.
  • Bradley, the original equipment manufacturer, also produces a repair kit (# 300-0760) which includes the cartridge (#300-0601), the gasket (#300-0602) and the sleeve and insert (#300-0935).
  • Not all single-handle shower faucets use a cartridge in the control valve. Some use a ball type; others, a disc design. Open the handle assembly to make sure yours is a cartridge type.
