Dripping or Low-Flow Faucet in San Jose, CA? Masters Plumbing Service Repairs Any Valve Type

Low water flow at a kitchen or bathroom faucet is almost always a clogged aerator or a partially failed cartridge β€” not low supply pressure. Stiff handles, dripping spouts, and leaks under the sink each trace to specific internal components. Our techs in San Jose know faucet valve anatomy across all the major brands and carry the parts to fix them.

4 Things That Set Our Faucet Repair Service Apart in San Jose, CA

Faucet repair looks simple until the wrong cartridge is installed, a seat-and-spring assembly is put in backwards, or a corroded packing nut strips during removal. Our techs know the specific disassembly sequence for the faucets they work on in San Jose, CA.

πŸ”©

Valve-Type Specific Expertise

Ceramic disc faucets from brands like Moen's newer series, American Standard, and European brands use a pair of ceramic discs that rarely fail but can crack from thermal shock (sudden cold water on a hot disc). Our techs carry common disc cartridge replacements for major brands.

🏷️

Brand Knowledge Across Major Lines

We identify the brand and model from the fixture, source the correct OEM or high-quality aftermarket cartridge, and install it correctly. Using the wrong cartridge on a pressure-balance shower valve doesn't just drip β€” it can cause scalding or cold-water bypass.

🚿

Shower & Tub Valve Specialists

Shower valves β€” particularly pressure-balance and thermostatic mixing valves β€” are more complex than a kitchen sink faucet and have safety implications if repaired incorrectly. We carry cartridges for the major pressure-balance valve brands common in San Jose, CA homes and understand the anti-scald setpoint calibration that should be verified after any shower valve cartridge replacement.

πŸ’§

Under-Sink Leak Diagnosis

Not every under-sink leak is the faucet itself β€” many are supply line connections, P-trap slip joints, garbage disposal collars, or drain body gaskets. Our techs trace the water source precisely before recommending a faucet repair or replacement.

Every Faucet Repair We Handle in San Jose, CA

Most faucet repairs complete in a single visit with parts on the truck.

Kitchen

Kitchen Faucet Repair & Replacement

Kitchen faucet issues typically present as: a dripping spout (worn cartridge or ball assembly), a leak at the base (failed O-ring at the faucet body), stiff or jerky handle movement (mineral deposits or corroded cartridge tracks), or reduced flow (clogged aerator or partially closed supply valve). We diagnose the cause, repair the specific component, and test for full leak-free operation.

Bathroom

Bathroom Sink Faucet Repair

Single-handle bathroom faucets use cartridge valves β€” one cartridge controls both hot/cold mixing and volume. When the cartridge wears, the result is a drip that typically starts slowly and worsens over months. We identify the cartridge model by the faucet brand and replace it with the correct OEM cartridge.

Shower

Shower Valve Cartridge Replacement

Shower pressure-balance valves keep the water temperature stable when someone flushes a toilet or runs a dishwasher. When the cartridge wears, you lose that temperature compensation β€” hot and cold water temperatures swing unpredictably during the shower. We replace pressure-balance cartridges for Moen, Delta, Kohler, and other common brands found in San Jose, CA homes.

Outdoor

Outdoor Spigot & Hose Bibb Repair

Freeze-proof (anti-siphon) hose bibbs found in colder San Jose, CA climates have a longer stem that shuts water off 8–12 inches inside the heated wall. When these fail or freeze-crack internally, the whole bibb typically needs replacement to restore the freeze-protection function.

Low Flow

Aerator Cleaning & Flow Restoration

Reduced flow at a kitchen or bathroom faucet is almost always a clogged aerator β€” the small screen-and-flow-restrictor assembly at the tip of the spout. Mineral scale from hard water accumulates in the aerator mesh over time, progressively reducing flow to a trickle. Aerator cleaning or replacement restores full rated flow in minutes.

Replacement

Full Faucet Replacement

We handle the full installation: shut the supply, disconnect the old faucet, inspect the supply lines and angle stop valves, install the new faucet, connect supply, adjust the aerator, and verify drip-free operation before leaving.

From Dripping Faucet to Fixed β€” 4 Clean Steps

We identify the valve type before ordering or installing any part. The right cartridge for your faucet brand is what produces a lasting result β€” not a generic part that fits loosely.

1

Call & Describe Your Faucet Symptom

If you know the brand β€” Moen, Delta, Kohler, Price Pfister β€” tell us. If not, the tech will identify it on-site from the valve body and handle design.

2

Valve Type Identification & Diagnosis

For many major-brand cartridges β€” Moen 1225, Delta RP46074, Kohler GP30413 β€” the part is on the truck and the repair proceeds immediately.

3

Flat-Rate Quote & Repair Execution

If the faucet body is corroded or the seat is damaged, we explain the repair complication and re-quote before proceeding.

4

Verify Zero Drip Before Leaving

We also confirm the angle stop valves under the sink operate β€” a seized stop valve that can't shut off in a future emergency is a problem worth noting while we're already under the cabinet.

What San Jose Customers Say About Our Faucet Work

β˜…β˜…β˜…β˜…β˜…

My kitchen faucet had been dripping for two years β€” I kept putting it off. Masters Plumbing Service's tech identified it as a Delta ball-type faucet and had the complete repair kit on his truck: new ball, springs, seats, and O-rings. The whole rebuild took 40 minutes. The faucet moves smoothly now and there's absolutely no drip. I only wish I'd called sooner given how much water I was wasting.

β€” K. Svensson, San Jose
β˜…β˜…β˜…β˜…β˜…

My shower temperature was impossible to control β€” any toilet flush or washing machine cycle would cause a cold spike mid-shower. Masters Plumbing Service replaced the pressure-balance cartridge in the Kohler valve, set the anti-scald stop at 120Β°F, and tested temperature stability by running the toilet while the shower ran. The swing went from 15+ degrees to less than 2. That's how a pressure-balance valve is supposed to work.

β€” P. & G. Delacroix, San Jose, CA
β˜…β˜…β˜…β˜…β˜…

Full bathroom faucet replacement β€” my old two-handle fixture was discontinued and no cartridges were available. Masters Plumbing Service supplied a quality Moen single-handle faucet in the same 4-inch centerset configuration, removed the old fixture, replaced the supply lines with braided steel, and installed the new unit. Clean, level installation. Also replaced both angle stop valves under the sink since the originals were 20 years old and barely turned.

Faucet Questions We Answer Every Day in San Jose

The more important issue: a drip that starts slow almost never stays at one drip per second. The cartridge or seat washer continues to deteriorate, worsening the leak until it's a steady stream or a handle that no longer shuts off at all.
For most faucets from established brands β€” Moen, Delta, Kohler, Price Pfister β€” replacement cartridges and repair kits are available and the fixture is worth repairing. We carry or can source these parts and prefer repair over replacement when the faucet body itself is in good condition.
Temperature swings during a shower β€” particularly when another fixture is used elsewhere in the house β€” indicate a failing pressure-balance cartridge. The cartridge's job is to compensate for supply pressure changes caused by other fixtures drawing hot or cold water, keeping shower temperature stable. When the cartridge wears, it loses this compensation ability and temperature follows the pressure fluctuation.
Stiffness in a faucet handle is usually caused by mineral scale accumulation on the cartridge tracks and O-ring contact surfaces, or a cartridge that's beginning to seize from corrosion. In many cases, a new cartridge β€” which comes with new lubricated O-rings and a clean ceramic or plastic body β€” restores smooth operation completely.
Cartridge faucets use a replaceable ceramic or plastic cartridge that slides in and out of the valve body β€” repair means pulling the old cartridge and installing the new one in the correct orientation. Ball faucets use a rotating stainless-steel or brass ball with ports that align with supply inlets β€” repair means a rebuild kit with new ball (if scored), springs, seats, and O-rings installed into the cleaned valve body.
These estimates assume the shut-off valves under the sink operate correctly. Corroded angle stop valves that need replacement before work can begin add 20–30 minutes. We tell you upfront if the stop valves are a concern.
