A dripping faucet is one of those household annoyances that starts small and somehow becomes impossible to ignore. That rhythmic *plink... plink... plink* at 2 a.m. isn't just testing your sanity—it's also sending your water bill higher with every drop. The good news? Most leaky faucets are fixable in under an hour with basic tools and a little know-how. Whether you're dealing with a steady drip from the spout or water seeping from the handle, this guide will walk you through diagnosing and repairing the problem like a pro.
Identify Your Faucet Type
Before you grab your wrench, you need to know what you're working with. Faucets generally fall into four categories, and each has a different internal mechanism. Compression faucets are the old-school style with separate hot and cold handles that you tighten down to shut off water flow. They're the most likely to leak because they rely on rubber washers that wear out over time. Ball faucets have a single handle that moves over a rounded ball-shaped cap and are common in kitchens. Cartridge faucets use a cylindrical cartridge to control water flow and can have one or two handles. Ceramic disk faucets are the newest design, with a single lever over a wide cylindrical body and nearly indestructible ceramic discs inside. To identify yours, look at the handle design and count how many there are. Take a quick photo of the faucet and any brand markings before you head to the hardware store—this will save you from second-guessing yourself in the plumbing aisle. Knowing your faucet type determines which replacement parts you'll need, so don't skip this step.
Gather Tools and Shut Off the Water
Nothing turns a simple repair into a flooded disaster faster than forgetting to cut the water supply. Locate the shut-off valves under the sink and turn them clockwise until firm—usually a quarter to half turn is enough. If your sink lacks individual shut-offs, you'll need to turn off the main water valve to your home, typically found near the water meter or where the main line enters your house. For tools, you'll need an adjustable wrench, flathead and Phillips screwdrivers, plumber's grease, and replacement parts specific to your faucet type. Keep a bowl nearby to catch residual water and to organize small parts as you disassemble the faucet. An old towel protects your sink from scratches and soaks up spills. A flashlight or headlamp helps you see into tight spaces under the sink and inside the faucet body. Lay out your parts in the order you remove them; this reverse roadmap makes reassembly straightforward.
Replace the Worn Components
With the water off and tools ready, plug the sink drain to prevent losing small parts down the pipes. Start by removing the decorative cap on the handle—often labeled "hot" or "cold"—to access the screw beneath. Unscrew and remove the handle, then work your way inward. For compression faucets, you'll find the stem assembly with its rubber washer at the bottom; this washer is almost certainly your culprit. Remove the brass stem with your wrench, pop off the old washer, and install a new one of identical size. Be sure the new washer seats flat without twisting. Ball faucets require replacing the springs, valve seats, and possibly the entire ball assembly. These come in convenient repair kits with all matching parts. Cartridge faucets need the old cartridge pulled out—some require a specialized puller tool—and a new cartridge pressed firmly into place. Ceramic disk faucets rarely leak, but when they do, the entire cylinder containing the disks usually needs replacement. In every case, apply plumber's grease to O-rings and moving parts to ensure smooth operation and extend the life of your repair. Reassemble in reverse order, tightening connections snugly but not forcing anything. Overtightening cracks ceramic disks, strips threads, and deforms washers—creating new leaks instead of fixing the original one.
Practical Tips
Patience saves more time than rushing ever does. Take photos at each disassembly step so you have a visual reference when things get tricky. If a part refuses to budge, apply penetrating oil and wait fifteen minutes rather than forcing it and risking breakage. When buying replacement parts, bring the old component to the store for exact matching—manufacturers often use similar-looking but incompatible sizes across product lines. After reassembly, turn the water back on slowly. Blast the supply open and you might jar loose sediment that clogs your aerator or damages fresh components. Check for leaks at full pressure, then test both hot and cold sides independently. A small drip that persists usually means a washer is crooked, a cartridge isn't fully seated, or debris is interfering with the seal. Disassemble again and inspect carefully rather than accepting partial success. Consider replacing both hot and cold washers or seals simultaneously, even if only one side leaks. They're the same age and material, so the other will likely fail soon. This prevents a repeat repair in a few months. Keep any specialty tools you purchase—faucet repair is a recurring home maintenance task, and you'll use them again.
When to Call a Professional
Some faucet problems extend beyond DIY territory. If you've replaced the obvious worn parts and the leak persists, you may have a cracked valve body, damaged threads, or corrosion that's preventing a proper seal. These issues often require replacing the entire faucet unit. Similarly, if you discover your sink's shut-off valves are frozen, corroded, or leaking themselves, that's a job best left to someone with the tools and experience to replace them without flooding your cabinet. Older homes with galvanized steel plumbing present additional challenges—aggressive disassembly can snap fragile pipes or break soldered joints. If you smell mold, see water stains spreading beneath the sink, or notice your water pressure dropping throughout the house, these symptoms point to broader plumbing system issues that need professional diagnosis.
