A Clarksburg homeowner's master bathroom shower had a slow drip that never stopped. We gave a written estimate to replace the Delta valve cartridge, and our technician came back to swap it in once the homeowner approved it.

The problem
The shower in the third-floor master bathroom had a slow, non-stop drip.
What our technician found
The shower runs on a Delta single-handle valve. Inside that kind of valve, a cartridge controls both the water flow and the temperature. When the cartridge's seals wear, water slips past even when the handle is off, which shows up as a steady drip from the shower. Replacing the cartridge with the matching part usually fixes this without opening the wall or replacing the whole valve.
What we did
- Looked at the leaking shower and wrote up an estimate to replace the Delta shower cartridge, parts and labor included.
- Picked up the replacement cartridge from the supply house.
- Came back for the scheduled visit after approval and replaced the shower cartridge in the master bathroom valve.
Parts used
- Delta shower valve cartridge
The result
Our technician replaced the cartridge and reported the job went well.
Tips for Clarksburg homeowners
- A shower that drips after it is turned off is usually a worn cartridge, not a bad showerhead. Fixing it early saves water and keeps mineral stains off the tile.
- Cartridges are specific to the faucet brand and model. Matching the original manufacturer's part gives the best fit and seal.
- Know where your main water shutoff is. Many shower valves have no shutoff of their own, so the water to the house has to be off for a cartridge swap.
- If the handle starts getting stiff or the temperature becomes hard to set, the cartridge may be wearing out before it starts to drip.
