Professional Faucet Repair in Sonora, CA — All Brands, Same-Day Service
Low water flow at a kitchen or bathroom faucet is almost always a clogged aerator or a partially failed cartridge — not low supply pressure. Stiff handles, dripping spouts, and leaks under the sink each trace to specific internal components. Our techs in Sonora know faucet valve anatomy across all the major brands and carry the parts to fix them.

Our Qualifications
What We Bring to Every Faucet Repair Call in Sonora, CA
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
Ball faucets, cartridge faucets, ceramic disc faucets, and compression faucets all fail differently and require different repair approaches. A ball-type faucet drips from a worn ball, springs, seats, or O-rings — all small parts that come in a manufacturer-specific repair kit. A cartridge faucet drip is almost always solved by cartridge replacement. Knowing which type you have before touching it determines whether the repair takes 30 minutes or 2 hours.
🏷️
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 — it can cause scalding or cold-water bypass.
🚿
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 Sonora, CA homes and understand the anti-scald setpoint calibration that should be verified after any shower valve cartridge replacement.
💧
Under-Sink Leak Diagnosis
Leaving a slow under-sink leak unaddressed damages the cabinet interior and subfloor. We identify the source, quote the repair, and execute it same visit in most cases.
Our Faucet Services
From Kitchen to Shower — Faucet Repair Across Your Home
Here's the full range of faucet repair work our techs handle in Sonora, CA — by fixture type and by symptom.
Kitchen
Kitchen Faucet Repair & Replacement
Older kitchen faucets with two separate handles use compression valves — each handle has a rubber seat washer that wears and needs periodic replacement. We stock washers and seat tools for these older designs, which are still common in Sonora, CA homes built before 1980.
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
After cartridge replacement, we verify anti-scald calibration — the maximum hot water limit set by the cartridge rotational stop — to confirm the valve won't deliver scalding water at full hot even if a supply pressure event occurs.
Outdoor
Outdoor Spigot & Hose Bibb Repair
Outdoor hose bibbs fail in two ways: a dripping spout (worn stem packing or seat washer) or a leak at the packing nut behind the handle (deteriorated packing material around the stem). Most hose bibb repairs involve replacing the seat washer and packing without removing the body from the wall.
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.
Masters Plumbing Service's Faucet Repair Workflow in Sonora
We identify the valve type before ordering or installing any part. The right cartridge for your faucet brand is what produces a lasting result — not a generic part that fits loosely.
1
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.
2
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.
3
Flat-Rate Quote & Repair Execution
You receive a flat-rate quote covering parts and labor before the water is shut off under the sink. Common repairs — cartridge replacement, ball assembly rebuild, aerator service — are straight-forward pricing with no variable labor component.
4
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
What Sonora Customers Say About Our Faucet Work
★★★★★
Single-handle Moen bathroom faucet dripping at the spout. Tech pulled the cartridge — an old 1200 design that was heavily scaled — swapped in a new Moen cartridge, adjusted the flow limiter, and the faucet has been silent for three months. Clean work, fast, reasonably priced.
— K. Svensson, Sonora
★★★★★
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, Sonora, CA
★★★★★
Full bathroom faucet replacement — 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.

Common Questions
What to Know Before Scheduling Faucet Repair in Sonora, CA
At one drip per second — which looks minor — a faucet wastes roughly 3,000 gallons per year. At average residential rates in CA, that's approximately $15–$25 per year per dripping faucet. A faster drip or multiple faucets multiply that cost. The EPA estimates that fixing all the leaks in an average home saves 10% on annual water bills.
For most faucets from established brands — Moen, Delta, Kohler, Price Pfister — 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.
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.
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 — which comes with new lubricated O-rings and a clean ceramic or plastic body — restores smooth operation completely.
Cartridge faucets use a replaceable ceramic or plastic cartridge that slides in and out of the valve body — 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 — 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.
