The Same Tap Keeps Dripping, and It Is Not the Plumber

Fixtures wear out on a schedule set by the water running through them. Harbor-area supply sits at the harder end of the Los Angeles range, so calcium and magnesium deposit on every surface the water crosses - cartridges, valve seats, flapper seats, aerators. Those are precisely the parts that fail.

None of that makes repair pointless. It shortens the interval. Where the same fixture is repaired repeatedly, the underlying cause is the water rather than the workmanship, and treating the water is a cheaper answer than a rolling series of cartridges.

Wilmington 90744 note: California SB 407 applies to property built on or before 1 January 1994. Housing here is overwhelmingly 1940 to 1969, so essentially every home in this ZIP falls inside that law - and most owners have never heard of it. What it requires, and what triggers it, is set out below.

Warning Signs

What a Failing Fixture Does First

Most of these appear well before the fixture actually fails. Acting at the first one is consistently the cheapest option.

A drip that came back

A tap repaired eighteen months ago and dripping again is not bad workmanship. Scale wears the cartridge and valve seat faster here, so the interval between repairs is genuinely shorter.

Handles getting stiff

Mineral deposit building up inside the cartridge. Stiffness almost always precedes the drip, which makes it the cheapest moment to act.

Toilet running between flushes

A flapper seal no longer seating, or a fill valve that has stopped shutting off cleanly. Both are inexpensive parts, and both waste water continuously until replaced.

Shower temperature swinging

Water going cold when a tap runs elsewhere points at the mixing valve. On older homes it often also means the valve predates current anti-scald requirements.

Flow dropping at one fixture

White deposit clogging an aerator or shower head. If flow has dropped across the whole house instead, the cause is the supply pipe rather than the fixture.

Disposal humming without turning

The motor is energised but the plate is jammed. Running it repeatedly in that state is what turns a jam into a burnt-out motor.

California Law

SB 407 Applies to Almost Every Home in 90744

A water-conservation law most owners have never heard of, aimed squarely at housing of exactly this age.

Built Before 1994

SB 407 covers property built on or before 1 January 1994

Alterations Trigger It

A remodel obliges replacement - a repair does not

Seller Must Disclose

Written disclosure of non-compliant fixtures, since 1 Jan 2017

1.28 gpf Toilets

California limit on every toilet sold since 1 Jan 2014

What the law says. SB 407 requires non-compliant plumbing fixtures in residential and commercial property built on or before 1 January 1994 to be replaced with water-conserving fixtures. For single-family homes the compliance date was 1 January 2017 - it is not a future obligation, it is one that has already passed.

What actually triggers enforcement. Since 1 January 2014, replacement is required when a property undergoes alterations or improvements as defined by the California Building Code and CALGreen. Repairs and maintenance are explicitly not alterations. That distinction is worth real money: fixing a running toilet does not oblige you to re-fit the bathroom, but remodelling that bathroom does bring the fixtures into scope.

The disclosure duty. Since 1 January 2017, a seller or transferor of most real property must disclose in writing whether the property contains non-compliant plumbing fixtures. In a neighbourhood where roughly nine in ten homes are rented and transfers are frequent, this comes up more often here than in owner-occupied areas - and it is the point at which deferred fixture work stops being deferrable.

The flow limits themselves. Toilets sold in California since 1 January 2014 are capped at 1.28 gallons per flush, with dual-flush models required to hit a blended rate no higher. New lavatory faucets are limited to 1.2 gallons per minute at 60 psi, and showerheads in new residential construction to 1.8 gallons per minute at 80 psi. A pre-1994 toilet typically uses 3.5 gallons or more, which is why replacing one cuts its water use by roughly two thirds - see toilet installation.

And the one that surprises people on a shower. Shower and tub-shower valves must be pressure-balancing, thermostatic or a combination, meeting ASSE 1016 or ASME A112.18.1/CSA B125.1, and must limit water at the showerhead to 120°F. Older homes routinely have valves that predate that requirement, which is why replacing one is not the like-for-like swap people expect: shower installation.

Repair or Replace?

Fix the Fixture, or Fit a New One?

Parts availability decides most of this. Age and California law decide the rest.

Repair When…

The fixture body is sound and parts are still available
The fault is a cartridge, flapper, fill valve or O-ring
The fixture is post-1994 and already compliant on flow
This is the first repair on that fixture
It is a match to the rest of the bathroom or kitchen

Replace When…

The body is cracked, or the finish has failed through
Parts are obsolete - chasing them costs more than the fixture
A pre-1994 toilet using 3.5 gpf or more against 1.28 today
Repeat failures on the same fixture
The property is being altered or improved, which triggers SB 407

The case people miss is the pre-1994 toilet. Repairing one is entirely possible, but it uses 3.5 gallons per flush or more against 1.28 today. On a metered supply the replacement pays back without any help from the law - and the law has an opinion as well.

Hard Water & Fixtures

Why Wilmington Fixtures Wear Out Faster

The mechanism is specific, and it explains almost every recurring fixture complaint in the harbor area.

The Numbers

Los Angeles tap water runs between 7 and 16 grains per gallon depending on the source blend serving a neighbourhood, and harbor-area supply sits toward the harder end because of its Colorado River share. That mineral load deposits directly inside the components that do the sealing.

The result is a shorter service interval, not a permanent problem. Whole-house treatment addresses the cause; component replacement addresses the symptom.

What Scale Does

Cartridge scaling

Calcium deposits on the cartridge surfaces stop it sealing cleanly and make the handle stiff. This is the single most common cause of a returning drip, and it is why the same tap needs attention again sooner than the owner expects.

Valve seat wear

The seat is the surface the washer closes against. Mineral grit acts as an abrasive every time the tap is used, so the seat roughens and the seal degrades faster than in soft-water areas.

Aerator and head clogging

White crust across the aerator screen or shower head face restricts flow at one fixture. It looks like a pressure problem and is not - flow loss at a single outlet is almost always deposit.

Flapper and fill valve fouling

Scale on the flapper seat prevents a clean seal, which is what makes a toilet run intermittently. Replacing the flapper without cleaning the seat usually returns the same fault.

What It Costs

Fixture Price Ranges in Los Angeles County

Published market ranges, not a quote. We publish them because no other plumber in the harbor area does - your own number follows the diagnosis.

Work	Range	What moves it
Toilet replacement	$320 - $976	Installed, materials and labour, Los Angeles
Kitchen faucet replacement	$200 - $600	Varies with hole configuration and supply lines
Shower cartridge replacement	$100 - $350	Often fixes the problem without touching the valve
Shower valve replacement	$170 - $625	LA average around $398; access behind the wall drives it
Garbage disposal installation	$320 - $776	Installed; straight replacement typically $570 - $673

Worth knowing before you agree to a valve replacement: a shower cartridge at $100 to $350 fixes a good number of the faults people assume need the full valve at $170 to $625.

Make Them Last

Six Habits That Extend Fixture Life Here

Three of these you can do yourself in under fifteen minutes, and one of them will save you a call-out.

Act on a stiff handle, not the drip

Stiffness is scale building on the cartridge, and it reliably precedes the drip. Servicing at that point is a cartridge; waiting until it drips can mean a worn seat as well, which is a bigger job on the same fixture.

Clean aerators and shower heads twice a year

Unscrew, soak in vinegar, refit. Ten minutes restores flow that people routinely mistake for a pressure problem and call a plumber about. On water at the harder end of the Los Angeles range this is the highest-value maintenance you can do yourself.

Test the toilet flapper with dye

Put food colouring in the tank and wait twenty minutes without flushing. Colour appearing in the bowl means the flapper is not sealing and the toilet is leaking continuously - the most common silent water waste in a house.

Fix a drip promptly - it is not trivial

The EPA puts a faucet dripping once per second at more than 3,000 gallons a year. On a metered supply that is money leaving continuously, and the repair is usually a single inexpensive part.

Keep fibrous waste out of the disposal

Celery, onion skins, coffee grounds and grease are what jam a disposal and foul the line beneath it. A disposal grinds food waste; it is not a route for everything that will physically fit down it.

Know your SB 407 position before you remodel

If your home predates 1994 - and in Wilmington it almost certainly does - an alteration or improvement triggers the obligation to replace non-compliant fixtures. Repairs do not. Finding this out during the project is worse than budgeting for it beforehand.

Plumbing Fixtures in Wilmington, CA - The Complete Guide

Fixtures are the part of a plumbing system people actually touch, which is why their faults get noticed first and understood least. Almost every recurring fixture complaint in this neighbourhood traces to one of two things: the hardness of the water, or the age of the fixture relative to California law.

How Hard Water Kills a Faucet

A cartridge faucet works by sliding a ceramic or brass cartridge against a seat to open and close the flow. Both surfaces have to stay smooth to seal. Water at 7 to 16 grains per gallon deposits calcium and magnesium on them continuously, and every operation of the handle drags that deposit across the sealing face.

The sequence is predictable. The handle stiffens first, because deposit is building in the cartridge. Then the seal degrades and the tap drips. Acting at the stiffness stage means replacing a cartridge; waiting until it drips often means the seat has roughened too. Faucet repair is cheap at the first stage and less so at the second.

Why the Same Toilet Keeps Running

A toilet runs when the flapper stops sealing against its seat, or when the fill valve no longer shuts off cleanly. Both are inexpensive parts. What people miss is that scale builds on the flapper seat as well as the flapper, so fitting a new flapper onto a scaled seat frequently reproduces the same fault within months.

The dye test settles it in twenty minutes: food colouring in the tank, no flushing, and any colour reaching the bowl means the flapper is leaking. It is the most common silent water waste in a house, and on a metered supply it is money leaving continuously. See toilet repair.

Shower Valves and the Anti-Scald Requirement

Shower and tub-shower valves in California must be pressure-balancing, thermostatic or a combination, meeting ASSE 1016 or ASME A112.18.1/CSA B125.1, and must cap water at the showerhead at 120°F. The purpose is to stop a toilet flush elsewhere in the house dropping cold pressure and scalding whoever is in the shower.

Homes built between 1940 and 1969 routinely have valves that predate this entirely. That matters practically rather than theoretically: it means a failing shower valve in a house of this age is not a like-for-like swap, because the replacement has to meet a standard the original never did. It also usually means opening the wall.

SB 407 - the Law Aimed at Housing This Age

California SB 407 requires non-compliant plumbing fixtures in property built on or before 1 January 1994 to be replaced with water-conserving fixtures, with a compliance date for single-family homes of 1 January 2017. Wilmington's housing stock is overwhelmingly 1940 to 1969, so this law covers essentially every home in 90744.

The trigger is what matters in practice. Since 1 January 2014 replacement is required when a property undergoes alterations or improvements as defined by the California Building Code and CALGreen - and repairs and maintenance are explicitly excluded. Fixing a fixture does not put you in scope. Remodelling the room does.

Since 1 January 2017 there is also a disclosure duty: a seller or transferor of most real property must state in writing whether the property has non-compliant fixtures. In a neighbourhood that is roughly 90% rental, where property changes hands more often than in owner-occupied areas, that duty surfaces regularly.

What Fixture Work Costs Here

Toilet replacement in Los Angeles runs $320 to $976 installed. A kitchen faucet replacement runs $200 to $600. A garbage disposal installation runs $320 to $776, with a straight replacement more typically $570 to $673. Shower valve replacement averages around $398 with a range of $170 to $625 - but a shower cartridge at $100 to $350 resolves a good share of the faults people assume require the whole valve.

That last point is worth pressing on when you get a quote. Ask whether the cartridge alone has been ruled out before agreeing to a valve replacement, because the two jobs differ by several hundred dollars and one of them involves opening a wall.

FAQ

Fixture Questions

California flow limits, SB 407, and why the same tap keeps dripping.

Does California require me to replace old plumbing fixtures?

For property built on or before 1 January 1994, yes. SB 407 requires non-compliant fixtures to be replaced with water-conserving ones, and the compliance date for single-family homes was 1 January 2017.

What actually triggers the SB 407 obligation?

Alterations or improvements as defined by the California Building Code and CALGreen. Repairs and maintenance are not alterations, so fixing a fixture does not trigger it - remodelling does.

Do I have to tell a buyer about non-compliant fixtures?

Yes. Since 1 January 2017 a seller or transferor of most real property must disclose in writing whether the property contains non-compliant plumbing fixtures.

What flush rate are toilets in California?

Every toilet sold in California since 1 January 2014 is rated at 1.28 gallons per flush or less. Dual-flush models must reach a blended rate no higher than 1.28 gpf.

Why can I not swap my old shower valve like for like?

Shower and tub-shower valves must be pressure-balancing, thermostatic or a combination, meeting ASSE 1016 or ASME A112.18.1/CSA B125.1, and must cap water at the showerhead at 120°F. Older homes often have valves predating that, so the replacement is not a direct swap.

Why does my faucet drip again so soon after being fixed?

Hard water. Harbor-area supply sits at the harder end of the 7 to 16 grains per gallon Los Angeles range, and scale wears the cartridge and valve seat faster. The interval is genuinely shorter here - it is the water, not the workmanship.

Is it worth repairing a pre-1994 toilet?

Usually not. Those use 3.5 gallons per flush or more against 1.28 today, so replacement cuts water use by roughly two thirds. On a metered supply that outweighs the repair fairly quickly.

My disposal hums but does not turn - is it dead?

Usually not. A hum means the motor has power and the plate is jammed. Repeatedly switching it on in that state is what burns the motor out, so stop and have the jam cleared.

What flow rates apply to new faucets and showerheads?

New lavatory faucets are limited to 1.2 gallons per minute at 60 psi. Showerheads in new residential construction are limited to 1.8 gallons per minute at 80 psi.
