How to Fix a Dripping Faucet: Step-by-Step Guide
A dripping faucet almost always traces back to a worn washer, O-ring, or cartridge seal inside the handle. Shut off the water supply valve under the sink, disassemble the handle with a wrench and screwdriver, swap the failed part, and reassemble snugly. Most repairs take under an hour and cost only a few dollars in parts, saving Parker-area homeowners gallons of wasted water each week.
That said, not every leak is a quick fix. If water keeps seeping after you replace the washers, or it pools around the base or handle, the valve seat or cartridge may be corroded – common with the hard water throughout the south Denver metro. When a repair stops feeling routine, a licensed 1st Choice Pro Services plumber can pinpoint the cause and prevent a bigger water bill.
