Fixing a Leaky Faucet: A Detailed DIY Guide 2026

A leaky faucet is a classic household nuisance that happens in every home. Here's how to fix it without calling a plumber. With a few basic tools and some patience, you can tackle this common issue yourself. For a successful repair, you might need some home improvement essentials from our collection.

Understanding the Leaky Faucet: Valve Stem and Washer

Over time, the faucet's sealing washer hardens. To get a tight shut-off, you may find yourself tightening the handle more and more. This soon compresses the washer completely, and without elasticity, it can no longer resist the water pressure. The fix is to replace the damaged washer. Inside the faucet, a "valve stem" with an O-ring is screwed in. Inside that, a piston moves, pushing the main washer against its seat to regulate water flow. This washer needs replacing when the faucet drips.

Replacing the Damaged Washer

To replace the washer, first shut off the water supply. Then, disassemble a few parts of the faucet. You'll likely need some basic tools from our home improvement range to get the job done.

• To remove the handle, take off the cap to access the retaining screw.
• Use a wrench to unscrew the brass assembly that controls the water flow.
• You'll notice two washers: the larger one is an O-ring that seals the threading of the mechanism; the other is the piston washer that stops the water flow.
• Carefully pry out the old washer with a thin flathead screwdriver, insert the new one, and reassemble the faucet in reverse order.

What If the Aerator Is Acting Up?

The faucet spout has an aerator (1), consisting of a ring with a washer, a perforated disc, and a small grid. Its job is to separate the water streams and mix them with air, making the flow less splashing. If small debris (common in water) builds up inside the aerator, the flow reduces. To fix this, loosen and remove the aerator to clean out deposits (2). It's wise to put a cloth between the pliers and the aerator to avoid scratching.

FAQ: Leaky Faucet Troubleshooting

Why does my faucet drip even after I replace the washer?

If the drip persists, the valve seat might be worn or corroded. You may need to resurface or replace it. Also, check that the new washer is the correct size and type for your faucet model. A home improvement kit can help with these advanced fixes.

How often should I replace faucet washers?

There's no set schedule, but if you notice dripping or have to tighten the handle more than usual, it's time to inspect and likely replace the washer. Regular maintenance can extend the life of your fixtures.

Can I fix a leaky faucet without shutting off the water?

No, always shut off the water supply before disassembling any part of the faucet. Otherwise, you'll have a geyser on your hands! Make sure you know where your shut-off valves are located.

What tools do I need for this repair?

Typically, you'll need a screwdriver, an adjustable wrench or pliers, and a replacement washer set. Having a well-stocked home improvement toolkit makes this job much easier.

Is it worth fixing a leaky faucet myself, or should I call a plumber?

For most standard faucets, this is a simple DIY repair that saves you the cost of a service call. If your faucet is very old or complex, or if you're uncomfortable with the task, a professional is always an option. But with the right supplies and tools, you can likely handle it yourself.

Additional Tips for a Smooth Repair

• Take photos as you disassemble the faucet to remember the order of parts.
• Place a rag in the sink drain to prevent losing small screws or parts.
• If the handle is stuck, use penetrating oil and let it sit before trying to remove it.
• Consider upgrading your faucet or other fixtures for a modern look. Explore our lighting and wall decor to complement your refreshed space.
