In Colton, faucet repair usually means dealing with scale from the city's hard groundwater and worn parts in a housing stock where about half the homes were built before 1980. Replacing fixtures on existing plumbing does not need a city permit, so most faucet jobs are simple to schedule. Call the number on this page to be connected with a local plumber in Colton.
Colton water and homes
The City of Colton runs its own water utility, drawing mostly local groundwater from seven city wells in the Colton/Rialto, Bunker Hill and North Riverside basins, with an interconnection to Rialto and, when needed, treated groundwater from San Bernardino. Its 2025 report lists total hardness averaging about 207 mg/L for the Colton/Rialto sources (range 150 to 230), and 160 mg/L for the Rialto source, with chlorine as the disinfectant. That is hard water, and it shows up as crusty aerators and stiff cartridges. About half of Colton's homes were built before 1980, and the median year built is 1979, so original stops and compression faucets are common, from the older blocks near La Cadena Drive to later tracts such as Cooley Ranch.
What to do first
- Shut the stops. Close the valves under the sink; if an old multi-turn stop will not move, use the main shutoff rather than forcing it.
- Look for the source. Check the spout, handle, base, supply lines and drain trap.
- Clean the aerator. For weak flow, unscrew it and soak it in vinegar to clear the scale.
- Note the faucet type. One handle or two, kitchen or bath, and any brand markings.
- Call the City for outside leaks. City crews handle main breaks and service line leaks on their side; after hours, call (909) 370-5000.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Drip from a two-handle faucet | Hardened washer or pitted seat |
| Drip from a single-lever faucet | Scaled or worn cartridge |
| Leak under the handle | Stem packing or O-ring |
| White crust at the spout | Mineral deposits from hard water |
| Wet cabinet floor | Corroded supply connection or leaking stop |
Cost factors
- Washer and seat repair, cartridge replacement or a full new faucet
- How much scale and corrosion have locked parts together
- Old stops and supply tubes replaced at the same visit
- Parts availability for older faucets
- Evening or weekend scheduling
The City of Colton's permit guide lists replacing fixtures on existing plumbing as work that does not need a permit, while replacing water or sewer lines and water heaters does. Building & Safety is at (909) 370-5079.
