A faucet that drips no matter how tight you turn the handle, a sink that's slow to drain, or a supply line leaking under the cabinet: these are some of the most common calls we get in Walnut, CA homes. Most are straightforward once a technician can see the actual part that's failed, which isn't always obvious from the symptom alone.
Common Faucet & Sink Issues
Persistent Dripping
Usually a worn cartridge, O-ring, or washer inside the faucet body, not something a tighter handle fixes.
Low Water Pressure
Can be a clogged aerator, a partially closed shutoff valve, or a supply line issue upstream.
Leak Under the Sink
Often a failed supply line connection or a corroded P-trap, both worth checking before it damages the cabinet.
Loose or Wobbly Faucet
Usually mounting hardware that's loosened over time, sometimes paired with a slow leak at the base.

Most repairs are completed the same visit.
Repair vs. Replace
Repair
- Cartridge, O-ring, and supply line fixes are usually same-visit
- Lower cost for an isolated failure
- Doesn't update an outdated or discontinued fixture
Replace
- Makes sense once a fixture is old enough that parts are hard to source
- Opportunity to upgrade finish or function
- Includes removal of the old fixture
What Affects the Price
A supply line leak under a sink that's gone unnoticed for a while can damage cabinetry; if we see that, we'll flag it separately from the fixture repair itself.
One detail worth knowing: a faucet that's dripped for months, even slowly, adds up on a water bill more than most people expect, and the mineral deposits from moderately hard local water tend to accelerate wear on the internal cartridge once a small drip starts. Addressing it early is usually a smaller repair than waiting until the fixture fails completely.
Bathroom and kitchen fixtures wear differently: a bathroom faucet sees lighter, more occasional use and often lasts longer before needing internal parts replaced, while a kitchen faucet's pull-down hose and diverter valve see enough daily cycles that they're usually the first components to fail on that type of fixture specifically.
If you're comparing repair against replacement on an older fixture, call (909) 505-3225 and describe what's failing; in many cases we can give you a realistic read on which direction makes more sense before scheduling the visit, rather than deciding on-site with no context.
Outdoor and utility faucets are worth a mention too: a hose bib that drips or won't fully shut off is a common source of a rising water bill that gets overlooked because it's outside rather than in a sink or bathroom, and it's worth including when you're troubleshooting an unexplained increase on a Walnut property, especially before assuming the leak is somewhere inside the house itself.
FAQs
A dripping faucet can come from a worn cartridge, O-ring, or valve seat, not just the washer; if replacing one part didn't fix it, another internal component is likely the actual cause.
Not always. It's often a clogged aerator or a partially closed shutoff valve at that fixture specifically, though it's worth checking if it's new and isolated to one spot.
In most cases yes, though very old or discontinued models sometimes require a close match rather than an exact one; we'll walk through the options.
Yes, including the hose and diverter valve issues common to pull-down and pull-out styles.
