A dripping faucet at one drip per second wastes over 3,000 gallons per year. Past the water cost, the drip often signals a worn cartridge or deteriorated seat-and-spring assembly that will worsen over time — eventually leaking continuously or becoming stiff and difficult to operate. Masters Plumbing Service's faucet techs in Cupertino, CA identify the specific valve type in your fixture, source the correct replacement cartridge or repair kit, and restore full, drip-free operation in a single visit.

Our Qualifications

Why Cupertino Homeowners Call Masters Plumbing Service for Faucet Work

We identify the valve type, source the correct OEM or quality aftermarket replacement, and restore the faucet to full operation — no leaks at the spout, no stiff handle, no drip.

🔩

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

Moen, Delta, Kohler, Price Pfister, American Standard, Grohe, Hansgrohe — each brand uses proprietary cartridge and valve designs that are not interchangeable. Moen uses their own 1200 and 1225 cartridge system; Delta uses ball valves in older fixtures and cartridges in newer ones; Kohler uses Rite-Temp pressure-balance cartridges in shower valves.

🚿

Shower & Tub Valve Specialists

Shower valves — particularly pressure-balance and thermostatic mixing valves — 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 Cupertino, CA homes and understand the anti-scald setpoint calibration that should be verified after any shower valve cartridge replacement.

💧

Under-Sink Leak Diagnosis

Not every under-sink leak is the faucet itself — 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.

Faucet Problems We Diagnose and Fix in Cupertino

Here's the full range of faucet repair work our techs handle in Cupertino, CA — by fixture type and by symptom.

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

Two-handle bathroom faucets (separate hot and cold) are often compression or ceramic disc designs. A drip from a two-handle set almost always comes from one side only — telling us which handle's valve needs attention.

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 — 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 Cupertino, CA homes.

Outdoor

Outdoor Spigot & Hose Bibb Repair

Freeze-proof (anti-siphon) hose bibbs found in colder Cupertino, 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 — 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.

Our Process

From Dripping Faucet to Fixed — 4 Clean Steps

Here's exactly how a Masters Plumbing Service faucet repair call runs in Cupertino, CA.

Call & Describe Your Faucet Symptom

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

Valve Type Identification & Diagnosis

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

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.

Verify Zero Drip Before Leaving

After repair, we run the faucet through the full temperature range, check the spout, base, handle, and supply connections for any drip, and confirm the aerator flow is unrestricted. The repair is complete when we can demonstrate it's dry and flowing correctly.

Customer Reviews

Real Faucet Repair Reviews from Cupertino, CA

★★★★★

My kitchen faucet had been dripping for two years — 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.

— K. Svensson, Cupertino

★★★★★

My shower temperature was impossible to control — 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 120°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.

— P. & G. Delacroix, Cupertino, CA

★★★★★

Low flow in the master bath — I assumed the pressure regulator was failing. Tech cleaned the aerator (heavily scaled), and flow went from a trickle to full pressure immediately. 10-minute fix, saved me from chasing a pressure problem that didn't exist.

Common Questions

Faucet Questions We Answer Every Day in Cupertino

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.

Replacement becomes the right answer when: the fixture body is corroded at the mounting surface or supply ports; the faucet is discontinued with no available replacement cartridge; or the fixture is very old and the homeowner wants to update to a water-efficient or different-style model.

A shower that fluctuates only at extreme handle positions (scalding at full hot, freezing at full cold) may actually have a correctly functioning but incorrectly set anti-scald stop — a mechanical rotational limiter on the cartridge that's adjustable without cartridge replacement.

If the stiffness is in a ball-type faucet, the cam and packing assembly may be binding — a rebuild kit with new cam, packing, and springs typically resolves it. We assess which type you have and quote accordingly.

Ball faucets are more common in older kitchen faucets and in some outdoor fixtures. Most modern single-handle fixtures are cartridge or ceramic disc designs. Identifying which type is present is the first step in every faucet repair call.

Cartridge replacement on a standard bathroom or kitchen faucet: 30–45 minutes. Ball faucet rebuild: 45–60 minutes. Shower pressure-balance cartridge replacement and anti-scald verification: 60–90 minutes. Aerator cleaning: 15 minutes. Full faucet replacement (fixture supplied): 60–90 minutes.
