Steady drip
Cartridge, seat or O-ring
The classic, and almost always a worn cartridge or seat kit. Cheap, quick, and worth doing promptly, both for the water and because the underlying scale is also working on the parts you cannot see.
Westminster, CA · hard water and seized cartridges
Faucet and fixture repair: drips, stiff handles and hard-water damage
Kitchen, bath and laundry fittings repaired with the right cartridge rather than replaced by default, and replaced honestly when the body has gone.
Repair by default
Most fixtures fail at a part, not at the fixture
A dripping tap, a handle that has stiffened, a spray head that has lost pressure, a spout that weeps at the base, nearly all of it comes down to cartridges, seats, O-rings and aerators. Those are inexpensive components, widely available for major brands for years after a model is discontinued, and fitted in a single visit. So the default here is to repair, and to say so even when replacement would be the larger invoice.
Hard water is what drives most of it in this area. Minerals scale up inside a cartridge and a valve body, which is why local fixtures stiffen and drip earlier than the same fixtures do elsewhere. It also gives a useful rule of thumb: a handle that has become stiff is on its way to seizing, and a seized cartridge is much more likely to break during extraction and take the fixture with it. Stiffness is the moment to act, not the thing to live with.
Single-fixture pressure complaints are worth separating out because they get misdiagnosed so often. A weak tap or shower on its own is nearly always a clogged aerator, a scaled cartridge or a partly closed stop valve: a few minutes of work. Only when several fixtures are weak together does the diagnosis move upstream to the regulator or the supply pipe, and testing distinguishes those before anyone opens a wall.
Where replacement genuinely is the answer, a corroded body, a failed finish, an unextractable cartridge, or a low-quality fixture that will be back with the same fault shortly, both prices go on the table and the choice is yours. And if you have already bought a fixture, fitting it is ordinary work; the useful conversation is a quick check of hole spacing and connections before you buy rather than after.
Ask About a Fixture
Brand and rough age if you know them. It usually decides whether parts are still available.
What actually goes wrong
Six fixture faults and their real causes
Five are parts. One is worth tracing carefully before anything is touched.
Stiff handle
Scale in the cartridge
Mineral build-up inside the cartridge and valve body. A new cartridge with the body cleaned out restores it. Left long enough it seizes, and a seized cartridge often cannot be extracted without damaging the fixture.
Weak at one tap
Aerator, nine times in ten
A clogged aerator, a scaled cartridge or a stop valve not fully open. Minutes to fix, and regularly mistaken for a whole-house pressure problem. If several fixtures are weak, the diagnosis moves to the regulator.
Weeping spout base
Body O-rings
Water appearing around the base of a spout when the tap runs is usually the O-rings sealing the spout to the body. Straightforward on most designs, and worth attending to because the water tracks down through the mounting hole into the cabinet.
Water in the cabinet
Trace before assuming
Faucet body, supply connections, stop valves, sink rim seal, tailpiece, trap or disposal flange, all present as a wet cabinet floor. Pressurised leaks get worse; drain leaks only show in use. Worth identifying properly rather than tightening things hopefully.
Spray head issues
Hose, diverter or scale
A pull-down head that will not spray, will not retract or leaks at the hose is usually a diverter, a worn hose or scale in the head. Parts are typically available by brand, and the whole faucet rarely needs to go.
How the visit runs
Identify, fit, and check the rest of it
Most fixture repairs are one visit and under an hour.
1
Identify the fixture and the fault
Brand and model where they can be found, the actual failure isolated rather than inferred, and stop valves tested: a stop that will not close is its own small problem and worth finding before you need it in a hurry.
2
Fit the correct part
Cartridges, seat kits, O-rings, aerators, supply lines and stops carried for common brands, so the great majority of repairs finish on the first visit rather than becoming a parts run.
3
Check the neighbours
While access is open, the other fittings at that sink get a quick look: supply connections, trap, stop valves, disposal flange. Finding a weeping stop valve during a faucet repair is the cheapest possible time to find it.
Book a Fixture Visit
Multiple fixtures on one visit is normal and usually the most economical way to do it.
Local context
Hard water sets the service interval here
Fixture life in this area is decided by water hardness more than by brand. The same cartridge that lasts a decade in soft water scales up and stiffens years earlier here, which is why drips, stiff handles and single-fixture pressure complaints are such a steady share of residential calls across Westminster and its neighbouring cities.
That has two practical consequences worth knowing. First, descaling aerators and shower heads periodically is genuinely worthwhile rather than a cosmetic exercise. It maintains flow and takes load off the cartridge behind them. Second, buying quality matters more here than it does in a soft-water region, because a fixture with a serviceable, widely-available cartridge can be repaired indefinitely, while a cheap sealed unit becomes disposable at its first fault.
The other local pattern is fixture age against bathroom age. Many bathrooms in this housing stock have had one or two rounds of refinishing while keeping the original rough-in, so a modern faucet often sits on a sixty-year-old supply arrangement with original stop valves behind it. Those stops are frequently seized, which matters most on the day something needs isolating quickly, and replacing them during a routine fixture repair costs very little.
Straight answers
Faucet and fixture questions
My faucet drips. Is that worth a service call?
Usually yes, on two grounds. A steady drip wastes a surprising amount of water over a month, and the cause is almost always a worn cartridge, seat or O-ring: inexpensive parts fitted quickly. The other reason is that a dripping faucet often means a seized or scaled cartridge, and a cartridge left to seize long enough can make the whole fixture unserviceable.
The handle is stiff or seized. Can that be fixed?
Generally yes. Stiffness is mineral build-up in the cartridge or valve body, and the fix is a new cartridge with the body cleaned out. Where it has gone too far, a corroded body, stripped stem or a cartridge that cannot be extracted without damage, replacement of the fixture becomes the practical answer, which is the argument for dealing with stiffness before it becomes seizure.
Water pressure is poor at just one tap. Why?
A clogged aerator is the most common answer by a wide margin, followed by a scaled cartridge and a partly closed stop valve under the sink. All three are quick fixes, and all three are regularly misread as a house-wide pressure problem. If several fixtures are weak together, that is a different diagnosis: see pressure and regulator service.
Can you find parts for an older faucet?
Often, and it is worth asking before replacing a good fixture. Cartridges and seat kits for major brands remain available for a long time, sometimes decades, and a quality older faucet is frequently better made than a mid-range new one. Where a brand has gone or the part genuinely no longer exists, that gets said plainly rather than used as a reason to replace something serviceable.
Should I repair or replace a leaking faucet?
Repair, if the body is sound and parts are available. It is cheaper and quicker. Replace when the body is corroded, the finish has failed, the cartridge cannot be extracted, the fixture is a low-quality unit that will need this again shortly, or when you want something different anyway. The decision gets made with both prices in front of you.
There is water in the cabinet under the sink. Where from?
Several candidates, and it matters which: the faucet body weeping down through the mounting hole, a supply connection or stop valve, the sink rim seal, the drain tailpiece or trap, or the disposal flange. The distinction matters because supply-side leaks are pressurised and get worse, while a drain leak only leaks when the sink is used. Both get traced properly rather than guessed at.
Are hard-water stains and crusting doing damage?
The visible staining is cosmetic, but what causes it is not. The same minerals scale up inside cartridges, aerators, shower heads and valve bodies, which is what makes fixtures stiffen, drip and lose flow years earlier than they should in soft-water areas. Descaling aerators and heads periodically genuinely extends fixture life here.
Can you install a fixture I bought myself?
Yes, that is common and completely reasonable. The only advice worth giving is to check the specification before buying: hole spacing, deck thickness, whether the sink is drilled for one hole or three, reach and height over the basin, and whether the supply connections suit what is there. A quick photo and measurement conversation before purchase prevents the most common disappointment.
