Low water flow at a kitchen or bathroom faucet is almost always a clogged aerator or a partially failed cartridge โ not low supply pressure. Stiff handles, dripping spouts, and leaks under the sink each trace to specific internal components. Our techs in Downey know faucet valve anatomy across all the major brands and carry the parts to fix them.

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 Downey, 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 โ 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.
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 Downey, CA homes built before 1980.
Single-handle bathroom faucets use cartridge valves โ one cartridge controls both hot/cold mixing and volume. When the cartridge wears, the result is a drip that typically starts slowly and worsens over months. We identify the cartridge model by the faucet brand and replace it with the correct OEM cartridge.
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 โ 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 Downey, CA homes.
Freeze-proof (anti-siphon) hose bibbs found in colder Downey, CA climates have a longer stem that shuts water off 8โ12 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 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 Downey, 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.
We also confirm the angle stop valves under the sink operate โ a seized stop valve that can't shut off in a future emergency is a problem worth noting while we're already under the cabinet.

My kitchen faucet had been dripping for two years โ I kept putting it off. Masters Plumbing Service's tech identified it as a Delta ball-type faucet and had the complete repair kit on his truck: new ball, springs, seats, and O-rings. The whole rebuild took 40 minutes. The faucet moves smoothly now and there's absolutely no drip. I only wish I'd called sooner given how much water I was wasting.
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 Downey, CA residential homes and businesses.
