That dripping faucet: repair the cartridge, or replace the whole fixture?

A dripping or stiff faucet is the small repair everyone puts off, and in a place where water is metered and not cheap, it is also one that quietly adds up. When you finally deal with it, the question is whether to repair the faucet you have or replace it with a new one. That decision is usually straightforward once you know what actually failed, and in San Tan Valley the culprit is almost always the same thing. Here is how to decide, and how to stop the same problem from coming back.

First, figure out what actually failed

Faucets fail in a few specific ways, and the failure points you toward repair or replacement. A drip from the spout is usually a worn cartridge, the replaceable valve inside that controls the water; that is the most repairable failure there is. A weak or spitting stream is usually a scaled aerator, the little screen at the tip, which is often just a clean. A stiff or stuck handle is usually mineral buildup inside the valve. A leak from the base of the faucet or from the connections underneath is a seal or supply issue. Most of these are repairs. The situations that push toward replacement are a faucet whose finish is peeling or corroding, or one so old that replacement parts are no longer made.

Repair or replace, by what failed

Match the symptom to the usual call.

Why it is almost always the water

Here is the pattern worth understanding, because it decides whether your repair actually lasts. Fixtures are where hard water does its most visible damage. Mineral scale clogs the aerator so the stream weakens, it builds up inside the cartridge so the handle stiffens or the faucet starts to drip, and it leaves the white crust on spouts and handles. So when a faucet fails on this water, it is usually the water that failed it. That is why a repaired faucet in an untreated home often needs attention again before long, while the same faucet in a softened home goes years without trouble. If you find yourself repairing the same fixtures repeatedly, the fixture is not really the problem.

The upstream fix that ends the cycle

The durable answer to recurring faucet trouble is not a better faucet, it is treating the water feeding it. A water softener stops scale at the source, which is why softened homes replace cartridges and clean aerators far less often. If you are already paying a plumber to repair one faucet, and you have noticed the same scaling on showerheads, glass, and other fixtures, that is the water telling you a softener would quietly cut your fixture maintenance across the whole house. It is the difference between fixing the symptom one faucet at a time and fixing the cause once. The faucet page covers the repairs themselves in more detail.

The small leak worth catching underneath

One thing worth doing whenever a faucet is being worked on is checking underneath the sink, because a slow leak there is easy to miss and expensive to ignore. A weeping supply stop or a damp cabinet floor is a small leak that, left alone, warps the particleboard cabinet base and can feed mold in the dark under the sink. Catching it while the faucet is already apart costs almost nothing; discovering it after the cabinet floor has swelled and delaminated costs a cabinet. So the practical move is to glance underneath any time a fixture is being repaired or replaced, and deal with a small drip before it becomes a real one.

The bottom line

Most dripping, weak, or stiff faucets are repairs, not replacements: a cartridge, an aerator clean, or a seal. Replace only when the finish is failing or the parts are obsolete. But the deeper answer, if you keep repairing the same fixtures, is that the hard water is the real culprit, and a softener is what ends the cycle across the whole house rather than one faucet at a time. And whenever a faucet is apart, check underneath for the small leak that is cheap now and expensive later.
