Diagnosing the Problem

Most clients assume a leaky faucet means total replacement, but more often than not it’s a worn-out washer or a corroded cartridge. I always start by identifying the issue: Is the leak happening when the handle’s off or only when moved? Does the handle feel loose or sticky? If water dribbles from the spout even when off, chances are the internal cartridge needs attention. If the handle wobbles or sticks, sediment might be gumming up the works.

Essential Tools and Preparation

Grab an adjustable wrench, flat-head screwdriver, Allen key, and plumber’s tape. Always shut off your bathroom water supply—usually two valves located under the sink—before digging in. Place a towel in the sink to catch stray screws (trust me, crawling on your knees searching for them isn’t fun). It helps to snap a quick photo of the faucet before disassembly, so reassembly is a breeze.

Step-by-Step Single Handle Faucet Repair

First, gently pop off the handle’s decorative cap—common in most American faucets—with a flat-head screwdriver. Underneath, loosen the screw (sometimes Allen-keyed) to remove the handle. Next, use the wrench to unscrew the retaining nut holding the cartridge in place. Once you’ve removed the cartridge, check for cracks, mineral build-up, or worn O-rings.

Replace worn parts with new ones—bring the old cartridge to the hardware store to match it. Clean internal faucet surfaces with white vinegar (for mineral deposits) and gently reassemble in reverse order. Don’t forget to use plumber’s tape on threaded connections for a leak-proof fit.
