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 Harper 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 Harper, TX.
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.
We identify the brand and model from the fixture, source the correct OEM or high-quality aftermarket cartridge, and install it correctly. Using the wrong cartridge on a pressure-balance shower valve doesn't just drip โ it can cause scalding or cold-water bypass.
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 Harper, TX 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.
Kitchen faucet issues typically present as: a dripping spout (worn cartridge or ball assembly), a leak at the base (failed O-ring at the faucet body), stiff or jerky handle movement (mineral deposits or corroded cartridge tracks), or reduced flow (clogged aerator or partially closed supply valve). We diagnose the cause, repair the specific component, and test for full leak-free operation.
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.
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.
Freeze-proof (anti-siphon) hose bibbs found in colder Harper, TX 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.
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 Harper, TX.
If you know the brand โ Moen, Delta, Kohler, Price Pfister โ tell us. If not, the tech will identify it on-site from the valve body and handle design.
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.
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.

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.
