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 โ eventually leaking continuously or becoming stiff and difficult to operate. Masters Plumbing Service's faucet techs in Angwin, 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.

We identify the valve type, source the correct OEM or quality aftermarket replacement, and restore the faucet to full operation โ no leaks at the spout, no stiff handle, no drip.
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.
Moen, Delta, Kohler, Price Pfister, American Standard, Grohe, Hansgrohe โ 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.
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.
Not every under-sink leak is the faucet itself โ 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.
Most faucet repairs complete in a single visit with parts on the truck.
Older kitchen faucets with two separate handles use compression valves โ 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 Angwin, CA homes built before 1980.
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 โ telling us which handle's valve needs attention.
After cartridge replacement, we verify anti-scald calibration โ the maximum hot water limit set by the cartridge rotational stop โ to confirm the valve won't deliver scalding water at full hot even if a supply pressure event occurs.
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.
Reduced flow at a kitchen or bathroom faucet is almost always a clogged aerator โ 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.
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 โ chrome, brushed nickel, oil-rubbed bronze.
Here's exactly how a Masters Plumbing Service faucet repair call runs in Angwin, CA.
Drip at the spout? Leak at the base? Stiff handle? Low flow? Knowing the symptom and, if possible, the faucet brand lets us arrive with the most likely replacement parts already stocked on the truck.
The tech identifies the faucet's valve type (ball, cartridge, ceramic disc, or compression), locates the specific cartridge or repair kit number for that model, and checks whether the required part is on the truck or needs to be sourced.
If the faucet body is corroded or the seat is damaged, we explain the repair complication and re-quote before proceeding.
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.

Single-handle Moen bathroom faucet dripping at the spout. Tech pulled the cartridge โ an old 1200 design that was heavily scaled โ swapped in a new Moen cartridge, adjusted the flow limiter, and the faucet has been silent for three months. Clean work, fast, reasonably priced.
My shower temperature was impossible to control โ 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 120ยฐF, 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.
Low flow in the master bath โ 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.

Our techs carry cartridges for the major brands most commonly found in Angwin, CA residential homes and businesses.
