  • Leaky faucet: Dripping water, even when the faucet is off, is a sign of a worn-out washer or O-ring.
  • Faulty handle: If your handle is loose, won't turn, or doesn't control the water flow, the problem could be a broken cartridge or set screw.
  • Low water pressure: If your shower isn't as powerful as it used to be, the issue might be a clogged aerator or a problem with your home's water supply.

Leaky faucets are often caused by worn-out washers or O-rings. Here's how to replace them:

  1. Turn off the water supply to your shower. The valves should be located behind the access panel near your shower.
  2. Remove the handle by unscrewing the setscrew on the underside. You might need an Allen wrench for this.
  3. Remove the cap and collar, then pull out the cartridge. You might need pliers for this.
  4. Inspect the washer or O-ring at the end of the cartridge. If it's worn or damaged, replace it with a new one.
  5. Reassemble the faucet in reverse order and turn the water supply back on.
