How to Fix a Dripping Faucet, and When to Call a Pro

Why faucets drip, and why it is worth fixing promptly

A faucet controls water with a moving part that presses against a seat to stop the flow. Over time that part, a rubber washer in an older compression faucet, a cartridge in most modern ones, or an O-ring at the base of a spout, wears out, and the seal it made starts to leak. The drip is not random; it is a specific worn part telling you it is done.

The reason to fix it sooner rather than later is not mainly the wasted water, which is real but modest. It is that worn parts do not stabilize, they keep wearing. The cheap version of this repair is a new cartridge now. The expensive version is when the constant flow erodes the valve seat or the valve body itself, and the whole fixture has to come out, which turns a faucet repair into a faucet replacement.

The DIY fix, step by step

For most homeowners this is a doable job with basic tools. The key is shutting off the water and identifying your faucet type before you start.

When it is bigger than a DIY job

A few situations turn a simple drip into a plumber's call, and several of them are more common in older Cartersville homes. If the shutoff valves under the sink will not turn or start leaking themselves (common on decades-old gate valves) stop, because you may not be able to control the water. If the faucet is corroded onto galvanized supply pipe, forcing it can crack the pipe. And if the drip has gone on long enough to erode the valve seat, a new washer will not hold.

Persistent low pressure at the same faucet is a different signal entirely. In a home with original galvanized supply, weak flow at one fixture can mean the pipe feeding it has corroded nearly closed, which points toward repiping rather than a faucet part. And a drip you cannot trace to the faucet at all may be a supply-line leak that calls for leak detection.

A note on old-house plumbing

Cartersville's older homes reward a little caution. The shutoff valves under a sink that has not been serviced in decades are the most likely thing to fail when you finally turn them. Replacing a seized gate valve with a modern quarter-turn valve is a small scheduled job that makes every future repair easier. It is also the kind of thing worth having a plumber do while they are already there for something else.

If you try the fix and the drip persists, or you open things up and find corroded parts you cannot match, there is no shame in stopping. A faucet repair is inexpensive for a plumber and far cheaper than the water damage a valve that fails mid-repair can cause.

Tools and parts to have on hand

A dripping-faucet repair goes smoothly or badly depending mostly on whether you have the right few things ready before you start. The tools are basic: an adjustable wrench, a set of screwdrivers including a small one for handle screws, needle-nose pliers, and often an Allen key for set screws hidden under the handle. A small container to hold parts in the order they come off saves a lot of guessing at reassembly.

Parts are the part people get wrong. Faucets are not universal, a cartridge, washer, or O-ring has to match the make and model, so the reliable move is to pull the worn part out first and take it to the store to match rather than guessing from a photo. Many homeowners buy a repair kit for their specific faucet brand, which bundles the likely-worn pieces together. Having plumber's grease on hand to lubricate a new O-ring or cartridge helps it seat and seal.

One more preparation matters more than any tool: know how to shut the water off. The valves under the sink are first choice, but in an older Cartersville home those may be seized, so confirm they turn before you commit, and if they do not, that is the sign to call rather than force them. Being ready to stop the water at the main as a backup means a surprise does not turn a small repair into a flooded cabinet.
