What your faucet is doing and what it means

Faucets fail in a handful of ways. The way yours behaves narrows the repair to one or two parts.

A steady drip from the spoutThe seat, washer, cartridge or O-ring inside has worn out. One drip a second adds up to many gallons over a month.Spout drip Water leaks around the base of the handleA cracked O-ring or a loose packing nut lets water creep up the stem and run down the outside of the fixture.Handle leak The spray is thin or splits in twoScale in the aerator screen reshapes the stream.

Pricing

What moves the price of faucet repair

Replacing a washer is not the same job as replacing a wall-mount fixture. Ask about pricing when you call.

Faucet design

Common cartridges are easy to source. Discontinued or imported fixtures may need a match or a swap.

Which room

A kitchen with a pull-down hose and sprayer has more parts than a bathroom lav.

The condition of the stops

Under-sink shutoffs that no longer close can add a step, since the water has to be shut off higher up.

Mounting style

Single-hole, deck-mount and wall-mount faucets each have their own access.

Scale on the parts

Mineral crust seizes nuts and cartridges and slows the job.

Have these ready for the call

By design

Four faucet designs, four ways to leak

Before anything else, work out which design your faucet is. The repair follows.

Brands vary. A photo of the handle helps.
Design	How to spot it	Why it drips	The usual repair
Compression	Two handles that turn several times	Rubber washer or seat wears	New washer, new seat, tighten the stem
Cartridge	One or two handles with a smooth, short motion	O-rings and seals go soft	Swap the cartridge
Ball	Single lever on a rounded cap	Springs and seats wear, cap loosens	Rebuild kit
Ceramic disc	Single lever, heavy and smooth	Seals under the discs or the cylinder crack	New disc cylinder

How does a faucet actually stop water?

Every design shuts the flow with a seal pressed against a seat. The handle moves a stem, a ball or a pair of ceramic discs, and the seal opens or closes a port. When the seal softens, flattens or collects grit, a thin film of water gets through, and that is the drip. Replacing the sealing part restores the shutoff.

Faucet repair in Mission Viejo, CA often finds the same two culprits: a rubber part that has gone hard, and a layer of mineral crust that stops the seal closing. Scale is a regular sight on Southern California fixtures, and it pairs with worn seals to speed things up.

Handle, stem, seal, seat

Simplified. Real faucets have more parts.

Why does my faucet drip only at night?

Pressure in a house tends to climb a little overnight, when few fixtures are running. A seal that is just barely tired will start to leak in those quiet hours. A drip that appears only at night, or only on the hot side, is a tired seal on that side. A dripping hot tap also wastes heated water, which makes the water heater run more often.

Tracking the drip

Hot or cold side?Feel the spout after the drip starts. Warm water means the hot seal.
Drip speedA drop a second wastes more than a drop every few seconds.
Count the handlesTwo handles can mean two worn parts.
Look for scaleA white crust around the spout means mineral buildup.

Notes to share on the call.

Mineral buildup

Aerators, screens and hard water: the quiet part of faucet repair in Mission Viejo, CA

A weak or messy stream is often scale in a tiny screen, not a failing faucet.

What does an aerator do, and why does it clog?

The aerator is the small screen threaded onto the end of the spout. It mixes air into the stream so it feels soft and uses less water. Minerals that precipitate when water warms collect there first, and so do bits of pipe scale or sediment from a recent repair. A clogged aerator sprays sideways, spits or reduces the flow to a thread.

Santa Margarita Water District’s 2026 water quality report puts its average hardness at about 15 grains per gallon. Three districts serve Mission Viejo, and your tap can differ by address, so check your water bill. If you are on the harder side, expect mineral crust on aerators, spouts and cartridge seats, and consider a softener or filtration for the whole house.

Reading the spray

Cleaning an aerator is a quick job.
Sign	Likely cause	What to do
Spray splits or sprays sideways	Scale in the aerator	Unscrew, soak and brush
Flow drops to a thread	Clogged inlet screen	Clean both screens
White crust on the spout	Dried mineral water	Soak in vinegar, wipe
Grit in the stream after a repair	Debris from the line	Flush, then clean the aerator
Flow weak on one side	Stop valve half closed	Open the stop all the way

Can I clean it myself?

Usually yes. Unscrew the aerator by hand or with a cloth and pliers, rinse the screen, soak it in vinegar for an hour and brush the crust off with an old toothbrush. If the flow still looks poor, the inlet screens or the cartridge may be partly blocked. A plumber then opens the faucet, and while there, replaces worn seals.

Aerator clean

Unscrew the tip
Wrap a cloth around it so the finish stays clean.
Soak and brush
Vinegar softens most mineral crust.
Rinse and refit
Seat the washer flat, tighten by hand.
Run the tap
Watch for a clean, solid stream.

A five minute job on most faucets.

Below the faucet

Supply lines, stop valves and the wet cabinet

The faucet is only the visible end. Water reaches it through two small hoses and two small valves under the sink.

Why is there water under the sink when the faucet looks dry?

Leaks in the cabinet have several sources: a supply line with a loose nut or a frayed braid, a stop valve that weeps at the stem, a drain connection with a worn washer, or the faucet itself leaking from the base. The test is to dry everything with a towel, wrap a dry paper towel around each connection, and run the water for a minute. The paper darkens at the culprit.

Braided supply lines last years but not forever, and a line that has bulged or corroded at the nut should be replaced soon. If you see wet wood, swollen particleboard or a musty smell, treat it as a small leak that has been going for a while. For the rest of the kitchen, garbage disposal repair covers the neighbor that shares the cabinet.

Finding the cabinet leak

Dry everything firstWipe pipes and valves so a new leak shows clearly.
Paper towel testWrap a strip around each joint and run the water.
Look at the braidRust at the nut or a bulge in the hose means it is aging.
Feel the stop valvesWet metal at the stem means the packing nut is leaking.

A two minute test with towels.

What if the stop valves will not close?

Old stop valves are the weak link of a faucet job. Many have not been turned in years, and the stem seizes or the rubber washer cracks. If the stop does not shut the water off, the plumber closes the house valve to work. Replacing the stops at the same visit saves the next faucet job from the same problem. See the guide on how to shut off your main water valve for when you need to stop everything.

Reading a stop valve

A bad stop can turn a small job larger.
Stop valve condition	What it means	Lean toward
Turns freely and shuts tight	Healthy	Keep
Turns but still drips past	Washer worn	Replace the stop
Will not turn	Seized stem	Replace the stop
Weeps at the stem	Packing worn	Tighten or replace
Green or white crust	Corrosion	Replace the stop and line

Other taps

Kitchen, bath, laundry and the outdoor spigot: each has its own faults

Different rooms use different faucets, and each has its own way of going wrong.

What is different about a kitchen faucet?

A kitchen faucet often carries a pull-down or pull-out spray hose, a separate soap dispenser or a filtered water line. The spray head collects scale. The hose can leak where it joins the spout. The weight that keeps the hose coming back may slip off its track. A leak at the base of the spout usually means the spout seal or the O-rings have worn. A plumber replaces these parts, and in some cases suggests changing the whole faucet when parts are no longer made.

A bathroom lavatory faucet is simpler: two handles or one, a pop-up drain and a short supply. A laundry or utility sink faucet takes more abuse because of detergents and hard use. Check the hot and cold labeling after any repair and run both sides.

Faucets by room

Common patterns by room.
Where	Typical fault	Typical repair
Kitchen pull-down	Hose leak, weight slips, scale in the head	Replace the hose or head
Bath lavatory	Cartridge drip, pop-up rod slips	Swap the cartridge, reset the rod
Laundry sink	Handle stem worn, spout loose	New stems, tighten the base
Utility sink with hose thread	Vacuum breaker leaks	Replace the breaker
Bar or prep sink	Small cartridge seals	Replace the cartridge

What about the outdoor spigot?

A hose bib that drips from the stem needs a new washer or packing. One that leaks at the vacuum breaker needs a new breaker. Water appearing inside the wall, in the garage or under the house where the spigot passes through is a pipe problem, not a stem problem. A damp spot near a hose bib that is not in use points toward the pipe, and leak detection separates the cases. A dripping hose bib also keeps the soil around the foundation wet.

Outdoor spigot leaks

A leak behind the wall can start at a hose bib.

Water near electricity

If water is dripping onto an outlet, a lamp or a plug strip, switch off power to that circuit at the panel before reaching into the cabinet. Then close the water and call.

Decide

Repair the faucet or replace it?

Seals and cartridges are small parts when they can be sourced. The choice often depends on the age and finish of the fixture.

Ask which row matches your faucet.
What you find	Lean toward	Why
Drip, faucet in good shape	Repair	Seal or cartridge swap
Pitted, flaking finish and a drip	Replace	The body is wearing as well as the seals
Parts no longer made	Replace	A match is not available
Handle stripped or cracked	Repair	Replace the handle and screw
Leak at the base of a wall mount	Open and repair	May involve the wall
Old faucet, old stops	Replace both	Avoids a second visit
Low flow but clean aerator	Look deeper	Check the stops and the line

What do I do to keep a repaired faucet working?

Clean the aerator every few months. Operate the stop valves once a year so they do not seize. Avoid cranking handles shut with force, since a firm turn is enough. If you are on harder water, wipe the spout dry after use. For a house with many aging fixtures, plumbing repair can handle the faucets, the stops and the supply lines in one visit, and signs of corroded pipes tells you what to watch.

Small habits

Questions

Common questions on faucet repair in Mission Viejo

What affects the cost of faucet repair in Mission Viejo?

The cost of faucet repair in Mission Viejo depends on the faucet design, the room, the condition of the stop valves and how easy the parts are to source. A washer change is smaller than a cartridge swap on a discontinued brand. Ask about pricing when you call, with the brand and room ready.

Why do two faucet repairs get different prices in Mission Viejo?

Two faucet repairs in Mission Viejo can differ because of the design, the access under the sink, seized stops and hidden corrosion. A bathroom lavatory is quicker than a kitchen pull-down with a hose and sprayer. Ask about pricing when you call, and share a photo if you can.

Is same-day faucet repair available in Mission Viejo?

A same-day visit for faucet repair in Mission Viejo is available, and a person picks up the phone at all hours. A leaking cabinet or a tap that will not close is first in line. Name the room, the handles and where the water appears.

What should I do first if a faucet won’t stop running in Mission Viejo?

Close the two stop valves under the sink by turning them clockwise. If they stick, close the main valve for the house, then call for faucet repair in Mission Viejo. Catch the water, dry the cabinet and keep electrical items away from the leak.

Why does my faucet drip even after I tighten the handle in Mission Viejo?

Tightening cannot fix a worn seal. The drip means the washer, seat or cartridge is no longer shutting the port. Tightening harder can damage the seat further. A Mission Viejo plumber replaces the sealing part, which restores a drop-free shutoff on most designs.

Can I repair a faucet myself in Mission Viejo?

Washers and aerators are common home jobs. Cartridges, balls and stems are harder, since they need the exact part and the right tools, and a stuck handle can snap. If the stops do not close, call first. A Mission Viejo plumber can also check the supply lines and stops while the faucet is open.

Why is my faucet water pressure low in Mission Viejo?

If one faucet is weak and others are fine, a clogged aerator or inlet screen is the likely cause. If every tap is weak, it points to the house line or regulator. See low water pressure for that side. A Mission Viejo plumber can test the pressure at an outdoor tap.

Is a leak under my kitchen sink urgent in Mission Viejo?

A drip into a bowl can wait for a visit the same day, but wet particleboard swells and molds within days. Close the stops, dry the cabinet and call. In a Mission Viejo condo, a leak can reach the unit below, so tell your building manager too.

Does hard water damage faucets in Mission Viejo?

Yes, hard water leaves crust on aerators and seats. Santa Margarita Water District’s 2026 report gives an average of roughly 15 grains per gallon, but the tap in your kitchen may read differently by address or district. Your water bill names your supplier.

How long should a faucet last in Mission Viejo?

A good faucet lasts for years, though the seals and cartridges inside wear sooner than the body. Hard water, daily use and rough handling shorten them. A Mission Viejo plumber can say if your fixture is worth repairing or if the parts and finish are near the end.

Can an outdoor spigot be repaired in Mission Viejo?

Yes. Dripping stems and leaking vacuum breakers are common and small repairs. Water that leaks inside the wall, in a garage or under the house is a pipe problem. Call for faucet repair in Mission Viejo and mention where the water is showing up.
