A dripping faucet seems small, but one drip a second wastes more than 3,000 gallons a year. A leak under the sink can be worse, because it soaks the cabinet floor out of sight. This guide shows where faucets leak, what each spot means and what you can fix yourself. Call (951) 299-3473 any time.

If you see water but cannot find where it comes from, our leak detection Murrieta CA team can trace it, even inside walls.

Why is my faucet leaking?

Most faucet leaks come from a worn part inside the faucet. A drip from the spout means a worn cartridge, washer or valve seat. Water at the handle points to worn O-rings. A puddle in the cabinet usually comes from a loose supply line, a worn nut or the sprayer hose. A leak at the base often means the faucet gasket or mounting nut has failed.

Where is your faucet leaking?

  1. From the spout, with the handle off. The cartridge or washer is worn. Murrieta's hard water speeds this up by leaving scale on seals.
  2. Around the handle. O-rings on the stem or cartridge are worn or dry.
  3. At the base of the faucet. The base gasket is worn, or water from the handle runs down.
  4. Under the sink. Check the supply lines, the shutoff valves and the pull-down sprayer hose.
  5. Hot side only. Heat wears the hot-side cartridge faster, so check it first.

How do you fix a dripping faucet?

Turn off both shutoff valves under the sink. Plug the drain so small parts do not fall in. Remove the handle, then the retaining nut or clip, and pull the cartridge or stem. Take it to a hardware store to match the brand and size. Install the new part, turn the water back on slowly, and check for drips.

  • Take a photo before you take anything apart.
  • Soak scaled parts in white vinegar to loosen mineral buildup.
  • If the shutoff valves will not turn or they drip, stop. Old valves can break.
  • Most name-brand faucets have a lifetime warranty on cartridges. Call the maker first.

What if the leak is under the sink?

Dry everything with a towel, then put a dry paper towel under each connection. Run the water and watch which one gets wet first. A slow leak at a supply line can rot the cabinet floor. Our guides on water under the kitchen sink and a leak under the bathroom sink go step by step.

High pressure can make faucets and supply lines fail early. Read high water pressure Murrieta to check yours. Many homes here run above 80 psi without a working pressure regulator.

Could it be the water heater?

If the hot side drips no matter which faucet you fix, or you see rusty water and popping noises, the water heater may be part of the problem. A worn heater or a failed relief valve can push pressure through the hot lines. Readers in south Orange County can get help from a local team for water heater repair Mission Viejo. In Murrieta, our guide on a water heater leaking explains what to do first.

When should you call a pro?

Call if the leak is inside the wall behind the faucet, if the cabinet floor is soft or stained, if the shutoff valves leak or will not close, or if your water bill jumped. A water leak detection visit in Murrieta costs about $200 to $550. A simple repair on an accessible pipe is often $300 to $1,500.

Frequently asked questions

Why does my faucet still drip after I turn it off hard?

The cartridge or washer inside is worn, so it cannot seal. Turning it harder can damage it more. Replace the cartridge or washer.

How much water does a leaky faucet waste?

One drip per second wastes more than 3,000 gallons a year. That shows up on your water bill over time.

Can I fix a leaky faucet myself?

Often yes. Replacing a cartridge or O-rings is a common DIY job. Call a pro if the shutoff valves are stuck or the leak is inside the wall.

Why is water pooling under my sink but the faucet looks dry?

The leak is usually at a supply line, a shutoff valve, the sprayer hose or the drain trap. Dry everything and watch each connection.
