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 Miramonte, 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.

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 Miramonte, CA.
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.
Shower valves โ particularly pressure-balance and thermostatic mixing valves โ 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 Miramonte, CA homes and understand the anti-scald setpoint calibration that should be verified after any shower valve cartridge replacement.
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 Miramonte, 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.
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.
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 Miramonte, 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.
For many major-brand cartridges โ Moen 1225, Delta RP46074, Kohler GP30413 โ the part is on the truck and the repair proceeds immediately.
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.
Full bathroom faucet replacement โ 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.
