Dripping faucets
Single-handle faucets usually need a new cartridge. Older two-handle faucets may need washers and seats. Bringing the brand and model, or a photo, speeds things up.
Running toilet, dripping faucet, a shower valve that will not hold temperature, or a disposal that hums and quits? We repair or replace it, and we pull the City fixture permit when one is required.
Most running toilets need a new flapper or fill valve, and most dripping faucets need a cartridge or washer. Newport Beach requires a plumbing permit to replace a fixture that breaks a trap seal, such as a toilet, sink, lavatory or garbage disposal. Swapping a washer, dryer, stove or built-in refrigerator does not. Call (949) 620-1945.
A running toilet is usually a worn flapper or a failed fill valve, and both are quick repairs.
| Problem | Usual cause | Usual fix |
|---|---|---|
| Runs on and off by itself | Flapper leaking into the bowl | Replace flapper and check the flush valve seat |
| Keeps filling, water in overflow tube | Fill valve set too high or failing | Adjust or replace the fill valve |
| Water on the floor at the base | Failed wax ring or loose closet bolts | Pull the toilet, reset with a new seal |
| Water dripping from the tank | Tank bolts or supply connection | Replace bolts, gaskets or supply line |
| Weak flush | Mineral scale in rim jets, partial clog | Clean jets, clear the trap or drain |
| Clogs often | Wipes, paper, or a partial block downstream | Clear the line; camera if it repeats |
EPA WaterSense suggests a simple test for silent leaks: put a drop of food coloring in the tank and wait 10 minutes without flushing. Color in the bowl means the flapper is leaking. Flush afterward so the tank does not stain.
Hard water matters here too. City water averaged about 14 grains per gallon of hardness in 2025. Over time, scale builds up on flush valves and in rim jets, which weakens the flush and wears seals faster.
Most drips come from a worn cartridge, washer or seat, and most can be fixed without replacing the faucet.
Single-handle faucets usually need a new cartridge. Older two-handle faucets may need washers and seats. Bringing the brand and model, or a photo, speeds things up.
Mineral scale clogs aerators and cartridge screens. Cleaning or replacing the aerator often fixes it in minutes.
A pressure-balancing or thermostatic cartridge that is worn or scaled cannot keep a steady temperature. Replacing the cartridge restores it.
Supply lines, shutoff valves and drain slip joints are the usual sources. Old shutoff valves often leak once they are turned, so we replace stuck ones.
Salt air corrodes exterior brass and copper near the harbor. A leaking or seized hose bib on Balboa Island or the Peninsula is a common, simple replacement.
New faucets, showerheads, valve trims and fixtures installed to the manufacturer's instructions, with care around high-end stone and tile.
A disposal that hums but will not turn is usually jammed; one that does nothing at all may have tripped its reset button or lost power.
Never put a hand in a disposal.
It is usually a small red button on the bottom of the unit.
Many disposals have a hex socket on the bottom for a jam wrench that turns the plate by hand.
Leaks from the body usually mean the unit needs replacement. In Newport Beach, replacing a garbage disposer needs a plumbing permit.
The City requires a plumbing permit for any fixture replacement that breaks a trap seal.
Larger remodels that pull building permits can also trigger California's SB 407 rule to replace older, high-flow fixtures with water-conserving models. Our permit guide explains when that applies.
Repair a toilet when the problem is a flapper, fill valve, seal or supply line. Replace it when the bowl or tank is cracked, or when it clogs constantly despite a clear drain.
When choosing a new toilet, look for the EPA WaterSense label, which marks models certified to use less water while meeting performance standards. A toilet replacement in Newport Beach needs a City plumbing permit, which we handle.
Every sink and toilet should have its own working shutoff so a leak can be stopped without shutting off the whole house.
Many older Newport Beach homes still have multi-turn shutoffs that have not moved in years. They often seize or start leaking the first time someone turns them, and hard water scale makes it worse. Quarter-turn ball valves are easier to close in a hurry. When we work on a fixture, we check its shutoff and supply line, and we tell you if they should be replaced. Braided supply lines also wear out, and an old one bursting is a common cause of sudden flooding under sinks.
With City water averaging about 14 grains per gallon in 2025 and IRWD water reporting 12.5 to 17.1, scale is the main enemy of fixtures in Newport Beach.
Small fixture leaks add up to thousands of gallons a year, according to EPA WaterSense.
EPA notes that replacing older toilets with WaterSense-labeled models could save a family of four more than 16,000 gallons of water a year. A leak you hear at night is also a leak you pay for on every bill, whether your water comes from the City, IRWD or Mesa Water.
When a permit triggers California's SB 407 rule, the City requires compliant fixtures that meet these maximum flow rates.
| Fixture | Compliant maximum |
|---|---|
| Toilet (water closet) | 1.28 gallons per flush |
| Single showerhead | 2.0 gallons per minute at 80 psi |
| Residential bathroom faucet | 1.5 gallons per minute at 60 psi |
| Kitchen faucet | 1.5 gallons per minute at 60 psi |
| Common and public-use bathroom faucets | 0.5 gallons per minute at 60 psi |
The statute treats a toilet built to use more than 1.6 gallons per flush, and a urinal built to use more than one gallon per flush, as noncompliant. For single-family homes, the City applies the rule to building alterations or improvements, and fixtures must comply before final approval. Water heater replacement and sewer line replacement are among the repair permits that do not trigger it. A simple toilet swap still needs a plumbing permit, so it makes sense to choose a compliant model either way.
If your shower has more than one showerhead on a single valve, the City's handout says the combined flow has to stay within the same limit, or the valve must let only one outlet run at a time.
Published national estimates put simple fixture installs in the low hundreds; published Newport Beach averages run higher.

The gap between national and local figures comes from the fixture itself, the condition of the flange, shutoff and supply line, access, and the City permit. A designer faucet on a stone counter is a different job from a builder-grade swap. You get a written price before work starts. See the plumbing cost guide for more.
A fixture visit runs in a fixed order so nothing gets damaged and nothing gets missed.
Tell us the fixture, what it is doing, and the brand if you know it. A photo of the model or the part helps the plumber bring the right cartridge or valve.
You get an honest arrival window, and a call if it changes.
The plumber finds the cause and gives you a written price for repair or replacement before starting.
If the job breaks a trap seal, such as a toilet, sink or disposal replacement, the City permit is pulled.
Floors, counters and stone are covered, and the water is shut off at the fixture or the main.
The fixture is installed to the manufacturer's instructions and checked for leaks, flow and drainage.
Old fixtures and packaging leave with the plumber.
Most under-sink leaks come from one of five places, and you can narrow it down with a dry paper towel.
Wipe everything dry, run the water, and touch each spot with a paper towel. Whatever gets wet first is your leak. If it is an angle stop or a supply line, close the main if the stop will not shut off, and call (949) 620-1945.
The same running toilet is a different job in a summer rental, a cottage and a new custom home.
A clogged or running toilet between guest stays needs a fast fix. Owners and managers can give us lockbox or access details so the repair does not wait on a key.
Salt air corrodes exterior brass and copper. A seized or leaking hose bib is a simple replacement, and a good moment to check the exterior shutoff.
New toilets, faucets and showerheads are chosen to the compliant flow limits and installed under the remodel permit.
Original shower valves in 1960s and 1970s homes often take a replacement cartridge. When parts are no longer made, the valve itself may need replacing, which can mean opening the wall behind it.
High-end fixtures, stone surfaces and HOA access rules mean extra protection and planning. Very high water pressure can shorten fixture life, so the plumber checks it.
A few small shortcuts cause most of the fixture floods we see.
The building type changes the job, from shutoffs to scheduling.
A real person answers 24 hours a day. You get an honest arrival window and a written price before any work starts.
Usually the flapper is leaking water into the bowl, or the fill valve is set too high and spilling into the overflow tube. Both are quick repairs. A dye test in the tank confirms a flapper leak in about 15 minutes.
Yes. The City of Newport Beach requires a plumbing permit for fixture replacements that break a trap seal, including toilets, sinks, lavatories and garbage disposers. We handle the permit.
The City's policy says appliances such as washers, dryers, stoves and built-in refrigerators do not require a permit for replacement. Fixtures that break a trap seal, like sinks and disposals, do.
Most single-handle faucets need a new cartridge, and older two-handle faucets need washers or seats. Turn off the shutoff valves under the sink first. If the valves are old and stuck, have a plumber replace them so they do not break.
Hard water scale usually clogs the aerator or the cartridge screen. Unscrew and clean the aerator. If that does not help, the cartridge or a shutoff valve may be partly blocked.
Turn off the power, then free the jam with a hex wrench in the socket on the bottom of the unit and press the reset button. Never put a hand inside. If it still fails or leaks, it likely needs replacement.
The pressure-balancing or thermostatic cartridge in the valve is likely worn or scaled. Replacing the cartridge usually restores steady temperature without opening the wall.
An angle stop is the small shutoff valve on the wall under a sink or behind a toilet. It lets you shut off water to one fixture. Old multi-turn angle stops often leak after being turned, and replacing them with quarter-turn valves is a common, inexpensive repair.
This Old House lists a Newport Beach average of $1,187 for toilet installation. HomeAdvisor's 2025 national range is $224 to $533. The toilet you choose, the flange, the shutoff and the City permit drive the real price.
The City's SB 407 handout lists 1.28 gallons per flush as the maximum for a compliant toilet. Showerheads are listed at 2.0 gallons per minute at 80 psi and residential faucets at 1.5 gallons per minute at 60 psi.
EPA WaterSense says a faucet dripping once a second can waste more than 3,000 gallons a year, and the average household's leaks can waste over 9,300 gallons a year.
Often, yes. Most temperature problems come from a worn or scaled cartridge that is replaced from the front. If the valve body itself has failed or parts are no longer made, the wall may need to be opened to replace it.
