Repair makes sense when
- The faucet is a known brand and the cartridge is still made
- The drip is from the spout, not the body or base
- The finish and handles are in good shape
- Only the aerator or a supply line is the problem

Quick answer
A running toilet usually needs a new flapper or fill valve, and a dripping faucet usually needs a new cartridge or washer. Test a toilet with the EPA dye test: put food coloring in the tank, and if color shows in the bowl after 10 minutes, it leaks. Fountain Valley's hard water wears these parts faster. Call (657) 669-4766 for repair or replacement.

Running toilet repair: flappers, fill valves and the dye test
A toilet that runs, hisses or refills on its own is almost always leaking water from the tank into the bowl past a worn flapper or a bad fill valve.
The U.S. EPA's WaterSense program says an old or worn flapper can cause a toilet to flush on its own or silently leak thousands of gallons a year. EPA recommends checking the flapper periodically and replacing it at least every five years. In Fountain Valley, where City water averaged about 13 grains per gallon of hardness in 2025, mineral scale on the flush valve seat and a stiffened rubber flapper are the usual reasons a seal fails sooner.
Do the dye test
EPA's method: put a few drops of food coloring in the toilet tank and do not flush. If any color shows up in the bowl after 10 minutes, you have a leak.
Check the water level
Lift the tank lid. If water is spilling into the overflow tube, the fill valve is not shutting off or is set too high. If the level is below the tube and the dye still reached the bowl, the flapper or flush valve seat is leaking.
Look at the flapper and seat
A warped, slimy or hard flapper will not seal. A white crust on the seat it closes against means scale, which can keep even a new flapper from sealing until the seat is cleaned or the flush valve is replaced.
Check the shutoff and supply line
The angle stop on the wall behind the toilet and the braided or plastic supply line wear too. A stop that will not close fully or a line with a bulge should be replaced while the plumber is there.
Common toilet, faucet and disposal problems and their usual fix
Most fixture calls come down to a few worn parts, and the symptom usually points straight to the part.
| Symptom | Likely cause | Usual fix |
|---|---|---|
| Toilet runs or refills on its own | Worn flapper, scaled flush valve seat, fill valve set too high | New flapper or fill valve, clean or replace flush valve |
| Weak or incomplete flush | Low tank water level, scale in rim holes and siphon jet | Adjust fill, descale rim and jet, or replace an old toilet |
| Water on the floor at the toilet base | Failed wax ring, loose closet bolts, cracked base | Pull and reset with a new seal, or replace the toilet |
| Toilet rocks | Loose or broken closet flange, uneven floor | Flange repair and reset |
| Faucet drips from the spout | Worn cartridge, washer or seats, often scaled | New cartridge or rebuild kit |
| Water under the sink | Leaking supply line, loose drain slip nut, worn faucet base seal | Replace line, tighten or replace drain parts |
| Low flow at one faucet | Aerator clogged with scale or debris | Clean or replace the aerator |
| White bits in a faucet screen, hot side only | Pieces of a water heater dip tube | Clean screens, check the water heater |
| Disposal hums but will not turn | Jammed flywheel | Free the jam, check for damage |
| Disposal is silent | Tripped internal reset, breaker, or failed motor | Reset, or replace the unit |
| Disposal leaks from the bottom | Internal seal failure | Usually replace the unit |
The white-bits row comes from the City of Fountain Valley's water quality FAQ, which says white particles in faucet strainers are probably pieces of the water heater's dip tube. If you see that, our water heater repair page explains what comes next.
How Fountain Valley's hard water wears out fixtures
City water averaged 217 parts per million of hardness in 2025, about 13 grains per gallon, and that mineral leaves scale on every seal, cartridge and screen it touches.
The City's 2026 Consumer Confidence Report, covering 2025, shows total hardness averaging 217 ppm, with a range of 171 to 256 ppm, or about 10 to 15 grains per gallon. In 2025 the City delivered 100 percent groundwater from the Orange County Groundwater Basin, managed by the Orange County Water District. In a normal year the mix is about 85 percent groundwater and 15 percent imported water. Either way, it is hard water.
Here is where that shows up in a Fountain Valley bathroom or kitchen:
- Toilet flappers and flush valve seats. Scale builds on the seat and the rubber hardens, so the seal leaks. This is the most common cause of a running toilet we see.
- Fill valves. Grit and scale keep the valve from shutting off cleanly, which causes hissing and slow refills.
- Faucet cartridges. Single-handle faucets use a cartridge that scale can stiffen until the handle is hard to move or the faucet drips.
- Aerators. The small screen at the tip of the spout catches scale flakes, and flow drops a little more every month.
- Shower valves and heads. Clogged spray holes and stiff valve cartridges follow the same pattern.
- White crust. Spots on chrome, glass and around the base of faucets are dried mineral, not a plumbing failure, but they show how much is in the water.
Cleaning an aerator in vinegar or replacing a flapper treats the symptom. A water softener treats the cause for the whole house. Our Fountain Valley water hardness guide explains the City's numbers and what they mean for each fixture.
Faucet repair or replacement
Repair a faucet when it is a quality model with available parts; replace it when the body is corroded, parts are discontinued, or the base leaks into the cabinet.
EPA WaterSense says a faucet that drips once per second can waste more than 3,000 gallons a year, about the water for more than 180 showers. A showerhead leaking 10 drips per minute wastes more than 500 gallons a year. Those drips are worth fixing even when the bill does not jump.
Replacement makes sense when
- The faucet body is cracked, corroded or leaking at the base
- Parts are no longer available or cost close to a new faucet
- You are remodeling or want a different style
- The old faucet uses more water than California now allows
A faucet replacement in a 1960s or 1970s Fountain Valley kitchen often turns up the same extras: old angle stops that will not close, rigid copper or chrome supply tubes, and a corroded sink drain. We replace those in the same visit when they need it, and the written price shows each item before work starts.
California water-conserving fixture rules for Fountain Valley homes
California law requires older homes to have water-conserving toilets, showerheads and faucets, and new fixtures must meet the state's current flow limits.
Older homes: Civil Code 1101.1 to 1101.8
These rules apply to residential and commercial property built and available for use on or before January 1, 1994. That covers nearly every house from Fountain Valley's 1960s and 1970s build-out. Under Civil Code 1101.3, a fixture is noncompliant if it is:
- a toilet made to use more than 1.6 gallons per flush
- a urinal made to use more than 1 gallon per flush
- a showerhead with a flow capacity of more than 2.5 gallons per minute
- an interior faucet that emits more than 2.2 gallons per minute
Civil Code 1101.4 says single-family homeowners were to replace noncompliant fixtures by January 1, 2017. For building alterations or improvements, the permit applicant must replace all noncompliant fixtures as a condition of final permit approval. And a seller must disclose in writing to the buyer whether the home has any noncompliant fixtures.
| Fixture | California limit | EPA WaterSense comparison |
|---|---|---|
| Toilet | 1.28 gallons per flush | WaterSense toilets use 1.28 gpf or less, 20 percent below the 1.6 gpf federal standard |
| Residential bathroom faucet | 1.2 gallons per minute | WaterSense bathroom faucets use 1.5 gpm or less |
| Kitchen faucet | 1.8 gpm, with an optional temporary 2.2 gpm | Not covered here |
| Showerhead | 1.8 gallons per minute | Not covered here |
EPA says older toilets can use as much as 6 gallons per flush, and that replacing old toilets with WaterSense models can save the average family nearly 13,000 gallons a year and more than $170 a year in water costs. Any fixture we install is a current California-compliant model, so a later remodel or sale does not turn it into a problem.
Toilet replacement: when to stop repairing
Replace a toilet when the bowl or tank is cracked, the base keeps leaking after a reset, or it is an old high-volume model that clogs and runs.
- A crack in the tank or bowl, even a hairline one
- A toilet that uses more than 1.6 gallons per flush, which California now calls noncompliant
- Frequent clogs from a weak, scaled-up older bowl
- Parts that keep failing because the flush valve seat is pitted
- A remodel that would trigger the Civil Code fixture rules anyway
Fountain Valley slab homes usually have the toilet bolted to a flange set in the concrete floor. When we pull an old toilet, we check the flange, the closet bolts and the drain opening. A broken flange is a common reason a toilet rocks or leaks at the base. If a toilet keeps clogging after it is replaced, the problem is further down the line, and our drain cleaning service or a sewer camera inspection finds it.
Garbage disposal repair, replacement and care
A disposal that hums is usually jammed and can be freed; one that leaks from its body or has a burned-out motor needs replacement.
Before you call
- Switch the disposal off and unplug it or turn off its breaker.
- Never put a hand in the disposal.
- Press the red reset button on the bottom of the unit.
- If it hums but will not turn, it is jammed. Many units have a hex socket on the bottom for a wrench that frees the flywheel.
- Water under the sink from the unit body, not the pipes, usually means the seals have failed.
What not to put down it
- Grease, oil and fat, which the City of Fountain Valley asks residents to keep out of all drains
- Fibrous scraps like celery and corn husks
- Potato peels and rice, which turn to paste
- Coffee grounds and eggshells in quantity
- Bones, fruit pits and anything that is not food
Grease is the big one. Fats, oils and grease cool and harden in pipes, and they build up in the kitchen line, the private sewer lateral and the public main. The City's sewer guidance asks residents not to pour grease down drains and points out that the property owner maintains the private lateral from the house to the public main. Scrape plates into the trash, wipe greasy pans with a paper towel, and run cold water while the disposal runs. A kitchen line already slowed by grease is a job for drain cleaning or hydro jetting, not a stronger disposal.
When a disposal needs replacing, the plumber checks the sink drain, the dishwasher connection and the trap at the same time. A replacement unit sized to the household and installed with new drain parts lasts longer than one bolted onto a corroded old drain.
Do fixture repairs need a City permit in Fountain Valley?
Small repairs usually do not; the City's exemption list covers clearing stoppages, repairing leaks in pipes, valves or fixtures, and pulling and resetting a toilet, as long as no valves, pipes or fixtures are replaced or rearranged.
The City of Fountain Valley's Work Exempt from Permits handout lists two plumbing exemptions. The first is stopping leaks in drains, water, soil, waste or vent pipe, unless a concealed pipe has to be removed and replaced, which is new work that needs a permit and inspection. The second is clearing stoppages or repairing leaks in pipes, valves or fixtures, and removing and reinstalling water closets, provided the repair does not replace or rearrange valves, pipes or fixtures.
So a new flapper, a cartridge, an aerator or resetting a toilet on a new wax ring fits the exemption. Replacing fixtures, moving a sink, adding a toilet or running new pipe is outside it. The Building Division at City Hall, 10200 Slater Ave, phone 714-593-4429, has the final word, and the City publishes Bathroom Remodel and Kitchen Remodel handouts for bigger projects. When a permit is required, we pull it. Our Fountain Valley plumbing permit guide covers the rest.

Fixture habits that save water and service calls
A yearly dye test, clean aerators and a no-grease kitchen prevent most fixture calls in Fountain Valley homes.
- Dye test every toilet once a year and replace flappers at least every five years, as EPA suggests
- Unscrew and soak faucet aerators and showerheads in vinegar a few times a year
- Open and close each angle stop under sinks and behind toilets once a year so they still work in an emergency
- Replace plastic or rubber supply lines that are bulging, cracked or more than several years old
- Keep grease out of the sink and the disposal
- Do the two-hour meter test if your bill jumps; EPA says fixing easy household leaks can save about 10 percent on water bills
- Know where your main shutoff is; our emergency plumber page shows how to find it

Questions Fountain Valley homeowners ask
Why does my toilet keep running?
Usually a worn flapper or a fill valve that will not shut off. In Fountain Valley's hard water, scale on the flush valve seat is a common cause too. EPA's dye test confirms it: food coloring in the tank that shows in the bowl within 10 minutes means a leak.
How do I check my toilet for a leak?
Put a few drops of food coloring in the tank and do not flush. EPA WaterSense says if any color shows up in the bowl after 10 minutes, the toilet leaks. The usual fix is a new flapper or a cleaned or replaced flush valve seat.
How often should I replace a toilet flapper?
EPA WaterSense recommends checking the flapper periodically and replacing it at least every five years. In Fountain Valley's 13-grain water, scale and hardened rubber can make a flapper leak sooner, so a yearly dye test is a good habit.
How much does it cost to fix a toilet in Fountain Valley?
HomeAdvisor's 2025 national range for installing a toilet is $224 to $533, and a typical Fountain Valley plumbing job runs $117 to $391 according to This Old House. Call (657) 669-4766 for an exact quote.
Do I have to replace old toilets when I sell my house in California?
Civil Code 1101.4 says homes built on or before January 1, 1994 were to have water-conserving fixtures by 2017, and sellers must disclose in writing whether the home has noncompliant fixtures. A toilet using more than 1.6 gallons per flush is noncompliant.
Why is the water pressure low at only one faucet?
Most often the aerator at the tip of the spout is clogged with mineral scale or debris. Fountain Valley's water averaged about 13 grains per gallon of hardness in 2025, so aerators clog often. Unscrew it and clean or replace it. If that does not help, the cartridge may be scaled.
Can I put grease down my garbage disposal?
No. Grease cools and hardens in pipes, and the City of Fountain Valley asks residents not to pour grease down drains. Wipe pans with a paper towel and put grease in the trash. Grease buildup in the kitchen line is a drain cleaning job.
Do I need a permit to replace a faucet or toilet in Fountain Valley?
Repairs like a new flapper, cartridge or resetting a toilet are exempt under the City's Work Exempt from Permits handout. The exemption ends when valves, pipes or fixtures are replaced or rearranged. We check with the Building Division and pull a permit when one is needed.
Should I repair or replace my garbage disposal?
Repair a disposal that is jammed or tripped its reset button. Replace one that leaks from the unit body or has a dead motor, since internal seal failures are not usually worth fixing.
