Faucet Repair in Sebastopol, CA β Drip Stopped, Pressure Restored
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 Sebastopol know faucet valve anatomy across all the major brands and carry the parts to fix them.

Why Sebastopol Homeowners Call Masters Plumbing Service for Faucet Work
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 Sebastopol, CA.
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 β 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
Moen, Delta, Kohler, Price Pfister, American Standard, Grohe, Hansgrohe β 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
Thermostatic shower valves (separate volume and temperature controls) are premium fixtures found in master baths where comfort and safety depend on correct cartridge specification. We don't substitute cheaper cartridges on thermostatic valves.

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 β Faucet Repair Across Your Home
Here's the full range of faucet repair work our techs handle in Sebastopol, CA β by fixture type and by symptom.
Kitchen
Kitchen Faucet Repair & Replacement
Older kitchen faucets with two separate handles use compression valves β 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 Sebastopol, 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 β telling us which handle's valve needs attention.
Shower
Shower Valve Cartridge Replacement
After cartridge replacement, we verify anti-scald calibration β the maximum hot water limit set by the cartridge rotational stop β 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
Freeze-proof (anti-siphon) hose bibbs found in colder Sebastopol, CA climates have a longer stem that shuts water off 8β12 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
Persistent low flow after aerator cleaning points to a partially failed cartridge that's not opening fully, or a kinked supply hose under the sink. We trace the restriction and resolve it.
Replacement
Full Faucet Replacement
When a faucet is discontinued (no available replacement cartridge), heavily corroded at the body, or simply past useful life, we replace the fixture. We supply faucets in the common hole configurations (single-hole, three-hole, widespread) and in finishes to match your existing hardware β chrome, brushed nickel, oil-rubbed bronze.

Customer Reviews
Real Faucet Repair Reviews from Sebastopol, CA
β β β β β
Single-handle Moen bathroom faucet dripping at the spout. Tech pulled the cartridge β an old 1200 design that was heavily scaled β swapped in a new Moen cartridge, adjusted the flow limiter, and the faucet has been silent for three months. Clean work, fast, reasonably priced.

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.

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.

Common Questions
What to Know Before Scheduling Faucet Repair in Sebastopol, CA
At one drip per second β which looks minor β a faucet wastes roughly 3,000 gallons per year. At average residential rates in CA, that's approximately $15β$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 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 20β30 minutes. We tell you upfront if the stop valves are a concern.
