Why your faucet leaks: the usual suspects
A faucet seals water with rubber or plastic parts that flex every time the tap is used. Scale from very hard water builds on those parts, they stiffen and crack, and water finds a path past them. The leak's location points to the failed part, which is the most useful diagnostic you have before opening anything.
- Drips from the spout: a worn cartridge or seat washer, the classic night-time drip.
- Leak at the base of the spout: a failed O-ring or a worn cartridge body.
- Water around the handle: a worn O-ring or packing nut.
- Leak under the sink: a supply line, fitting, or valve problem, not a faucet-internal one. Treat that as a different repair.
If water is pooling under the cabinet, check the supply lines and shutoffs first. Our faucet repair in Anaheim page covers the cases where the problem is bigger than a seal.
Steps that can fix a dripping faucet
These steps suit a standard cartridge or compression faucet, the kind in most Anaheim kitchens and bathrooms. They can be quick when the replacement part is on hand and nothing is stuck or corroded. If any step resists, stop rather than forcing it; a snapped shutoff or a stripped screw costs more than the drip did.
Step 1: Shut off the water
Close the shutoff valves under the sink, turning clockwise until they stop. Open the faucet to release pressure and confirm the water is off. If a shutoff is stuck or weeping, do not force it; that valve is now part of the repair.
Step 2: Plug the drain
Drop the stopper or stuff a rag in the drain. Small screws, springs, and clips are easy to lose down an open drain, and retrieving them is rarely quick.
Step 3: Remove the handle
Pop off the decorative cap and unscrew the set screw underneath, then pull the handle straight up. If it is stuck, a vinegar-dampened rag wrapped around the base can loosen scale. Do not pry with force against a finished surface.
Step 4: Expose the cartridge or stem
Remove the retaining nut or clip and note the cartridge's orientation before pulling it. A photo at this stage saves confusion later, because many cartridges fit only one way.
Step 5: Replace the worn parts
Match the old cartridge or washers exactly, ideally by taking the old part with you. In Anaheim's very hard water, check the valve seat for scale and clean it gently before fitting the new part, so the new seal does not sit on a rough surface.
Step 6: Reassemble and test
Refit in reverse order, turn the water on slowly, and check the spout, the handle base, and under the sink. A drip that persists after a correct cartridge swap points to a seat, valve-body, or supply problem, and that is the point to call.
Tools and parts you need
An adjustable wrench, a set of screwdrivers, pliers, a rag, and the correct replacement cartridge or washer set for your faucet model. The model name is usually under the handle cap or on the faucet body; without it, matching parts is guesswork. Keep the old part until the repair is tested.
Common mistakes to avoid
- Forcing a stuck shutoff valve until it breaks.
- Fitting a cartridge that looks close but is not the exact model.
- Over-tightening the retaining nut, which can crack the cartridge or distort the seal.
- Ignoring a leak under the sink while fixing a spout drip; the two may share a cause, or may not.

Frequently Asked Questions
How do I fix a leaking faucet in Anaheim?
Shut off the water, remove the handle, pull the cartridge, and replace the worn seals with an exact match. Reassemble and test. If the drip persists after a correct swap, the seat or valve body is the next suspect.
What causes a faucet to leak in Anaheim?
Worn seals and cartridges, accelerated by scale from very hard water, plus age and, in some homes, high pressure. The leak's location usually identifies the failed part.
Can I replace a faucet cartridge myself in Anaheim?
Often, yes, if you have the exact cartridge for your model. The main risks are a stuck shutoff valve and over-tightening the retaining nut. If either feels wrong, stop and call a plumber.
What affects faucet repair cost in Anaheim?
Whether the fix is a seal swap, a cartridge, or a valve or supply-line repair, plus access and parts availability for your model. A phone quote based on the symptoms and the model is the reliable step.
When should I call a plumber for a leaking faucet in Anaheim?
When the leak is under the sink, the shutoff will not close, the faucet body is cracked, or a correct cartridge swap has not stopped the drip.
