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 Thermal know faucet valve anatomy across all the major brands and carry the parts to fix them.

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.
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.
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.
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.
Here's the full range of faucet repair work our techs handle in Thermal, CA โ by fixture type and by symptom.
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 Thermal, 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.
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 Thermal, CA homes.
Freeze-proof (anti-siphon) hose bibbs found in colder Thermal, 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.
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.
We identify the valve type before ordering or installing any part. The right cartridge for your faucet brand is what produces a lasting result โ not a generic part that fits loosely.
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.
You receive a flat-rate quote covering parts and labor before the water is shut off under the sink. Common repairs โ cartridge replacement, ball assembly rebuild, aerator service โ are straight-forward pricing with no variable labor component.
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 Thermal, CA residential homes and businesses.
