In a Loma Linda plumbing emergency, close your main valve, and if there is a gas smell, leave and call 911 and SoCalGas at 1-800-427-2200. The City runs water and sewer, with after-hours emergencies at (909) 356-3805. For problems inside your property, call the number on this page to be connected with a local plumber in Loma Linda.

The call itself
Calling the number puts you through to an independent plumber who serves Loma Linda. Tell them the address, what you are seeing, and whether the water is off. If someone in the home relies on medical equipment or cannot easily leave, mention it, since it changes how the plumber plans the visit. Ask about after-hours pricing before work begins. No arrival time is promised; it depends on the hour and the schedule.
What changes the cost
- Timing. After-hours calls typically cost more than weekday service.
- Cause. Some problems are obvious; others need leak detection or a drain camera.
- Access. Slab, wall and ceiling leaks take more work to reach.
- Permits. The City of Loma Linda Building and Safety Division, (909) 799-2836, issues permits, and online applications go through its Citizen Self Service portal.
Loma Linda conditions
Loma Linda is built around Loma Linda University and its medical center, and the eastern half of the city, Bryn Mawr, was once a separate unincorporated community. The City runs its own utilities: water production, distribution and maintenance, plus sewer maintenance. Sewage from Loma Linda is treated by the San Bernardino Municipal Water Department. For service and billing, the City Finance Department is at (909) 799-2845. For water, sewer or street emergencies after hours, the City lists (909) 356-3805. Use that line for a broken main or a public sewer overflow; your own pipes and drains are a plumbing job.
The median home here was built in 1983, so a lot of water heaters, supply lines and drain lines are of an age where failures happen. San Timoteo Creek runs through the city from southeast to northwest and has flooded parts of it in the past, which is a reminder that heavy winter storms can push water into low spots and overload yard drainage.
Before the plumber arrives
- Close the main and open a low faucet
- Shut off gas or power to a leaking water heater
- Do not run water while drains are backing up
- Move electronics and important papers out of wet areas
- Clear a path to the heater, main and cleanout
