How to Stop a Dripping Faucet (and When to Call)

What a drip actually is

A faucet drips because the part inside that is supposed to seal the water off no longer does. In most modern faucets that is the cartridge, a replaceable unit that wears out; in older ones it is a washer and seat. When it wears, water gets past even with the handle closed, which is the drip. It is a small part and usually an inexpensive one, which is why a drip is worth fixing rather than tolerating.

The reason to fix it promptly is that a steady drip wastes a surprising amount of water over a month, and in a desert city that is water you are paying for and the region is short on. A drip is not urgent the way a burst pipe is, but it is not free to ignore either, and the fix is generally simple once the right part is in hand.

The Glendale hard-water reason it happens

Here is why Glendale faucets seem to start dripping without warning: hard-water scale builds up inside the cartridge and on the sealing surfaces over time until they no longer seal. The faucet did not fail suddenly; the minerals finally scaled up the part enough to let water past. The same scale crusts the aerator at the tip, which is why the stream splits or slows, and stiffens the handle so it gets hard to turn.

That mineral wear is also why a cheap faucet does not last here. If you are replacing rather than repairing, a quality ceramic-disc cartridge resists scale far better than a low-end valve that will be dripping again within a year. Treating the water with a softener extends the life of every faucet in the house, which is the long-term answer to recurring drips.

What you can do yourself, and how

For a confident DIYer, a dripping faucet is a reasonable project. Turn off the supply stops under the sink and open the faucet to release pressure. Take note of the faucet brand and model, because the cartridge has to match. Remove the handle and the retaining parts, pull the old cartridge, and take it to the store to match it exactly. Clean the scale off the surfaces, seat the new cartridge, and reassemble. Cleaning or replacing the aerator at the same time restores a weak stream.

Two things trip people up. First, hard-water scale can make parts stubborn to remove, so patience beats force, which cracks things. Second, if the shutoff stops under the sink do not fully close, that is its own problem to flag, because you will want them working the next time. If any of this feels uncertain, a straightforward faucet repair is a quick professional job.

When a drip means calling instead

Some faucet problems are not really the faucet. A leak at the base of the faucet or underneath the sink usually means a failed O-ring or a supply-line connection, not the cartridge, and chasing the drip at the spout will not fix it. If water is pooling under the sink, that is the connection to check. Repeated drips right after a repair can mean the faucet itself is corroded and better replaced than repaired again.

The bigger flag is when several fixtures are weak or dripping on the same line. That points upstream to the supply piping, not the faucets, and replacing three faucets will not solve a pipe problem. If your older Glendale home has weak, sometimes rusty flow across multiple fixtures, the real conversation is about the supply lines, sometimes a section of repiping, rather than any one faucet.

Don't forget the outdoor hose bibs

The faucets most likely to fail unnoticed are the outdoor hose bibs, because nobody watches them. A hose bib that drips wastes water straight onto the ground where you never see it, and a worn washer or a cracked valve is the usual cause, the same simple repair as an indoor faucet. It is worth checking them when you check the rest.

Outdoor faucets also carry the valley's freeze risk. On the few hard-freeze nights each winter, water left in an exposed hose bib can freeze and split it, and a hose left connected traps water in the line and makes it worse. Disconnecting hoses before a freeze and, on older homes, considering a frost-proof sillcock that shuts off inside the warm wall are the two moves that prevent a cracked outdoor faucet from becoming an indoor leak come spring.
