If the tap you fixed last month is dripping again, the washer was probably never the problem. Replace the cartridge or the worn valve seat instead and the drip usually stops for years rather than for a fortnight. That is the argument of this piece, and the rest of it is the evidence. Most kitchen mixers built in the last two decades do not seal with a flat rubber washer at all, so the washer packet on the shelf is solving a fault your tap may not have. A homeowner searching leaky faucet anaheim ca and one standing over a sink in Leeds get handed the same advice, and it fails both of them for the same reason.
Valve design is one of the few things in a kitchen you can actually look up. A faucet maker’s May 2026 guide comparing the common cartridge types puts ceramic disk cartridges at 10 to 20 years or more of service against 3 to 10 years for compression valves. Those are the manufacturer’s own figures, so read them as a range and not a promise. The gap is still wide enough to explain why one household changes washers every spring and another has not touched the tap since the kitchen was fitted.
The Washer Myth Survives Because It Sometimes Works
Swap a washer on a genuinely old compression tap and the drip stops. That is a real repair, and it is why the advice refuses to die. Trouble starts when the same fix gets aimed at a single-lever mixer, where sealing is done by a cartridge and a seat rather than by a squashed rubber disc. You can fit the new washer, tighten everything down, and buy yourself about two weeks.
Cartridges And Seats Wear Before Washers Do
Inside a mixer, water is shut off by two polished surfaces sliding across each other. Grit gets between them. Once a seat is scored, no amount of pressure from the handle will close that gap, which is exactly why the twist keeps getting harder every month. What usually turns up when the tap comes apart is a seat with a fine ring worn into it and a cartridge whose faces have gone dull. The washer, when there is one, often looks fine.
So the handle is not stiff because it is old. It is stiff because you are asking it to do a job the seat can no longer do.
Hard Water Damages The Seat Not The Handle
Hard water leaves scale, and scale is abrasive. In a hard-water household those ceramic faces get lapped by mineral grit every time the tap opens, which drags a cartridge’s real life toward the bottom of any published range. Type leaky faucet anaheim ca into a search bar and the first pages are still full of washer tutorials, none of which mention water hardness. Anaheim sits on the same mineral-heavy supply that furs up a kettle in a season.
A Drip Is Not Harmless Background Noise
Measure it before arguing about it. Put a marked jar under the spout at bedtime and read it at breakfast: a drip you can barely hear will often fill a hundred millilitres overnight, and a quick one passes half a litre. A tap that drips overnight has already failed, whatever the handle position suggests. The jar keeps score, which is more than memory manages.
Then Versus Now In Faucet Design
Fifteen years ago most homes had separate pillar taps with a compression valve and a rubber washer, and the washer genuinely was the wear part. A packet of assorted washers under the sink was a sensible thing to own. Today’s mixers moved the sealing job inside a sealed cartridge, and that cartridge is a model-specific part you order by brand and code rather than match by eye (yes, this is less satisfying than it used to be). The repair got more reliable and less improvisable at once.
Fixing The Right Part Ends The Cycle
Identify the tap, order the matching cartridge with a seat kit, and the parts bill on a typical mixer stays modest. Say you set a hundred and fifty dollars as an illustrative ceiling for parts: most jobs land well under it, and the ones that do not are usually taps worth replacing outright. The saving is not really the money. It is the end of the loop, because a third washer in one year costs an evening each time and leaves the drip precisely where it started. Take the tap apart, look at the seat, and replace what is actually worn.
