Leaky faucets are one of the most common household annoyances, but many leaks can be stopped with a few basic tools and a bit of patience. In this guide, we walk you through identifying your faucet type, gathering the right parts, and performing a safe, effective repair.

What causes leaks

Most kitchen and bathroom faucet leaks come from worn-out seals, washers, or cartridges. The exact fix depends on the faucet design—compression, ball, cartridge, or ceramic disk models. A quick inspection after turning off the water can help you determine which component is failing.

Safety and preparation

Before you start, gather basic tools: an adjustable wrench, Phillips and flat-head screwdrivers, pliers, a small bowl for parts, and replacement washers or cartridges. Turn off the water supply to the faucet (and to the house if needed) and plug the drain to prevent losing small parts down the drain.

Step-by-step repair

1) Identify the faucet type: majority are compression (two handles), cartridge (single handle), ball, or ceramic disk. 2) Disassemble carefully: remove handles with a screwdriver, then core components. 3) Inspect for wear: look at washers, O-rings, cartridges, or seals. 4) Replace the worn part with the correct replacement kit. 5) Reassemble and test for leaks by turning the water back on slowly and watching the connections.

Detailed tip: for compression faucets, replacing the worn washer usually stops the drip. For cartridge or ceramic-disk faucets, replacing the cartridge or disk assembly often solves the issue. Don’t overtighten nuts, as that can crack fittings and cause new leaks.

Testing and maintenance

After reassembly, run the faucet for a few minutes to confirm the leak is gone. If it persists, you may need to reseat the valve stem or replace additional seals. Regular inspection of seals and cartridges can prevent future drips and keep water waste down.

If you’re uncomfortable with any step or dealing with hard-to-reach plumbing, consider calling a licensed plumber. For simple repairs, many hardware stores offer guidance and compatible replacement parts.
