Understanding and Repairing a Dripping Faucet

A dripping faucet is more than just an annoying sound. It's a sign of a potential plumbing problem that can waste water, increase your utility bills, and even lead to damage to your fixtures. Fortunately, with a little knowledge and the right tools, you can often diagnose and repair a dripping faucet yourself, saving time and money.

Identifying the Source of the Drip

The first step in fixing a dripping faucet is to pinpoint the source of the leak. This may be as simple as visually inspecting the faucet for obvious leaks or as complex as disassembling the faucet and examining its internal components. Common causes of drips include worn-out washers, damaged O-rings, or faulty valve seats. The location of the drip can provide valuable clues about the underlying problem.

Drip from the faucet spout: This is typically caused by a worn-out washer or cartridge. The washer is a small, rubber or plastic disc that sits inside the faucet stem and helps to seal the valve when the handle is turned off. Over time, the washer can wear down, allowing water to leak past it. A cartridge is a more complex assembly that includes the washer and other internal components. If the cartridge is worn or damaged, it can also lead to a drip from the spout.
Drip from the base of the faucet handle: This is usually caused by a defective O-ring or a loose packing nut. The O-ring is a small, rubber seal that prevents water from leaking around the base of the handle. If the O-ring is damaged or worn, water can leak past it. The packing nut helps to hold the stem in place and prevent water from leaking around it. If the packing nut is loose, it can also cause a drip from the base of the handle.
Drip from the base of the faucet body: This could indicate a damaged valve seat or a leak in the supply line. The valve seat is the surface that the washer seals against to prevent water from leaking. If the valve seat is damaged or pitted, the washer may not be able to seal properly, causing a drip. A leak in the supply line, which connects the faucet to the water main, can also cause a drip from the base of the faucet body.

Repairing the Faucet

Once you've identified the source of the drip, you can start the repair process. The approach will vary depending on the specific issue. Here's a breakdown of common repairs:

Worn-out washer: Replacing a worn-out washer is a relatively simple repair. You'll need to remove the faucet handle, unscrew the stem nut, and remove the old washer. Then, insert a new washer of the same size and type, tighten the stem nut, and reassemble the faucet.
Damaged O-ring: To repair a damaged O-ring, you'll need to remove the faucet handle and carefully remove the old O-ring. Then, install a new O-ring of the same size and type, making sure it's properly seated in the groove. Reassemble the faucet handle and tighten the packing nut.
Damaged valve seat: Repairing a damaged valve seat is more complex and may require specialized tools. You'll need to remove the faucet stem and inspect the valve seat for damage. If the valve seat is pitted or worn, you may be able to resurface it with a valve seat dressing tool. If the damage is severe, you'll need to replace the valve seat entirely. This will require removing the faucet stem and replacing it with a new one.
Faulty cartridge: Replacing a faulty cartridge is a more involved repair that typically requires removing the entire faucet stem. You'll need to purchase a new cartridge that is compatible with your faucet model. Once you have the new cartridge, follow the manufacturer's instructions for installation. This may involve removing the old cartridge, installing the new one, and then reassembling the faucet.
Leaking supply line: If the leak is coming from the supply line, you'll need to replace the damaged section of the line. This will involve turning off the water supply to the faucet, disconnecting the supply line, and replacing the damaged section with a new one. Make sure to use the correct type of pipe and fittings for your plumbing system. Tighten all connections securely to prevent leaks.
