Nearly every drip is a repair, and an inexpensive one at that. A faucet drips because a small internal part, a cartridge, a washer, an O-ring, has stopped sealing, and swapping it is cheap. Renton's relatively soft city water helps here too, because scale is rarely what wore the faucet out, so the odds favor the internal parts rather than the whole fixture being the problem. You replace a faucet when the body is corroded, the finish has failed, or parts for an old model no longer exist, and in soft-water Renton that comes up less often than people assume.
So the default answer to a drip is fix it, and the burden of proof is on replacement, not the other way around.
What is actually dripping
A faucet's job is to seal water off completely when it is closed, and a drip means the part responsible for that seal has stopped doing it. In a cartridge faucet, that is a worn cartridge; in older designs, a washer or a valve seat. A handle that has gone stiff or loose is usually the same cartridge on its way out. Every one of those is a serviceable, replaceable part, which is why the reflex to reach for a whole new faucet is usually premature.
It is also worth not simply living with the drip, tempting as that is. Left to run, even a slow drip adds up to a genuinely wasteful amount across a year, and each drop keeps scouring the valve seat it passes, so tuning it out can quietly upgrade a cheap cartridge job into a slightly larger one later on.
Why Renton's water tilts the odds toward repair
In genuinely hard-water regions, scale builds up inside a faucet and grinds it toward an early replacement, which pushes those homeowners toward swapping fixtures more often. Renton is not that. The city draws its water from local wells and Springbrook Springs and treats it to be gentle on plumbing, and it runs relatively soft, so scale is much less often the reason a faucet fails here.
That difference is not academic, it changes the recommendation. A soft-water faucet with a worn cartridge usually has plenty of life left in its body, so replacing the cartridge genuinely fixes it rather than just postponing the replacement you would face in a hard-water town.
| What you see | Likely cause | Repair or replace |
|---|---|---|
| A drip, a stiff handle | Worn cartridge or washer | Repair |
| Weak flow at one tap | A clogged aerator | Repair |
| A leak at the base | Reseal or new O-ring | Repair first |
| Corroded body, dead finish | The faucet is finished | Replace |
When replacement is the honest call
Some faucets really are past saving, and pretending otherwise just wastes money on parts. Once the body has corroded, the finish has flaked or pitted past the point of looks, a base leak refuses to hold no matter how it is resealed, or the maker has stopped producing parts for an old model, you are into replacement rather than repair. At that stage, fitting new internals is throwing good parts at a fixture that has already run its course.
Replacement is also the natural moment to deal with the shutoffs under the sink, which everyone forgets until they seize. Fitting a new faucet with fresh, working shutoffs is what keeps a future cartridge swap from turning into a bigger job because the valve beneath it will not close.

The weak-flow myth people confuse with a leak
A single tap running weak gets blamed on all sorts of dramatic causes, but the usual culprit is dull: the aerator, the little screen at the tip of the spout, has silted up with sediment. Cleaning or replacing it is about the cheapest fix in plumbing and restores the flow immediately. That is a purely local faucet issue, confined to the one tap.
The distinction that matters is whether it is one tap or all of them. If every fixture in the house runs weak, that is not a faucet problem at all, it is a whole-house pressure question that points at the pressure reducing valve or the supply. Telling those two apart saves you from replacing a perfectly good faucet in pursuit of the wrong thing.

Questions homeowners ask
Is a dripping faucet even worth calling about?
Yes, because it is usually a cheap cartridge or washer fix, and left alone it wastes water and wears the valve seat it drips past. It is one of the more cost-effective repairs in the house, and it rarely means buying a new faucet, so it is worth handling rather than tuning out.
Does Renton's water wear faucets out faster?
Not the way it does in a hard-water town. Because the local supply is drawn from wells and springs and treated to be easy on plumbing, it stays on the soft side, so mineral scale is seldom what finishes a faucet here, and worn internals usually are. That is a big part of why repairing, rather than replacing, is so often the right call in this city.
Why is only one of my taps weak when the rest are fine?
Almost always a silted-up aerator, the screen at the spout, which is a quick clean or swap. If instead every tap in the house runs weak, that is a whole-house pressure issue rather than a faucet fault, and it points to the pressure regulator or the supply, not the fixture.
When should I just replace the faucet instead of repairing it?
Once the body has corroded, the finish has given out, or nobody makes parts for the model anymore. Past that point a repair only defers the inevitable, and a new faucet, set on fresh working shutoffs, is the smarter place to put the money than another round of internals in a fixture that is already done.
Can you fix a faucet that leaks at its base rather than dripping?
Usually yes. A base leak is often a reseal or a new O-ring rather than a whole new faucet, so it is worth diagnosing before replacing. It is only when the body itself is compromised that a base leak tips into replacement territory.
Should I replace the shutoff valves while the faucet is out?
It is a good moment to check them, since seized shutoffs are the thing that turns a future five-minute cartridge swap into a bigger job. If they are stiff or weeping, replacing them while everything is already apart saves a return trip later.
