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 β eventually leaking continuously or becoming stiff and difficult to operate. Masters Plumbing Service's faucet techs in Lancaster, 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 Lancaster, 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 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 valves β particularly pressure-balance and thermostatic mixing valves β 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 Lancaster, 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 β 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 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 Lancaster, 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 β telling us which handle's valve needs attention.
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 β 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 Lancaster, CA homes.
Freeze-proof (anti-siphon) hose bibbs found in colder Lancaster, 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.
Reduced flow at a kitchen or bathroom faucet is almost always a clogged aerator β 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.
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.
We identify the valve type before ordering or installing any part. The right cartridge for your faucet brand is what produces a lasting result β not a generic part that fits loosely.
If you know the brand β Moen, Delta, Kohler, Price Pfister β tell us. If not, the tech will identify it on-site from the valve body and handle design.
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 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.
Had a hose bibb that dripped at the packing nut all summer. Tech replaced the packing material and seat washer in 20 minutes. Also told me the freeze-proof stem length was correct for my wall depth, which was reassuring heading into winter.
Low flow in the master bath β 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 Lancaster, CA residential homes and businesses.
