In an Upland emergency, close the house shutoff, and if you smell gas, leave and call 911 and SoCalGas at 1-800-427-2200. A mainline leak after hours goes to Upland Police Dispatch at (909) 946-7624. For leaks, backups and failed equipment on your property, call the number on this page to be connected with a local plumber in Upland.

When it counts as an emergency
- A supply line, angle stop or hose has let go and water is spreading across the floor
- Toilets, tubs or the kitchen sink are backing up with wastewater
- The water heater tank is leaking or the relief valve will not stop discharging
- You hear water running inside a wall or under the floor with everything shut
- A pipe has cracked after a frosty night
- Gas odor near an appliance (leave first, then call 911 and SoCalGas)
A slow drain, a running toilet tank or one weak faucet can be scheduled for a normal weekday.
Upland's utility setup
Water in Upland comes from the City itself. Public Works handles City-side water leaks and the City's water meters, and you can reach it for service requests and leaks at (909) 291-2930. After hours, a leak on a water main goes to Upland Police Dispatch at (909) 946-7624, and the City sends a crew. Anything past the meter that belongs to the house, such as the yard line, the pipes in the slab and the fixtures, is something a plumber repairs.
About 80 percent of Upland's supply is local groundwater, supplemented with San Antonio Canyon surface water and imported State Water Project water. The Utilities Division completed a service line inventory focused on homes built before 1987 and publishes the report on its water quality page, which is worth checking if your house is that old and a line is being replaced. Upland homes, like most in the valley, sit on slabs, so a hidden supply leak often shows up as a warm floor or a meter that keeps turning.
Things that change the cost
- When you call. Evening, weekend and holiday work usually costs more than a weekday slot.
- Where the failure is. An exposed pipe in a garage is quicker than one under a slab or inside a finished wall.
- Repair or replace. Clearing a clog or swapping a valve is small; replacing a heater or a section of line is larger.
- Permit work. The City of Upland Building and Safety Division takes permit requests online through its Citizen Self Service portal, and larger replacements may need one.
When you call the number
You will reach an independent plumber who serves Upland. Explain what failed, whether the water is off, and the street address. Ask about after-hours rates up front. How soon someone arrives depends on the time and the plumber's schedule, so no arrival window is promised here.
