Loma Linda runs its own municipal water utility, so the City decides which properties need a backflow assembly and how test results are reported; ask the provider for its program details. For a test request, a failed device or a new service to protect, call the number on this page to be connected with a local plumber in Loma Linda.
What happens when you call
You'll be connected with an independent plumber who works in Loma Linda. Explain what the device protects and why you're calling: a City notice, a leak, a failed test or a new irrigation, fire or commercial line. Read off the make and size on the assembly if you can, and mention whether the building is a home, an office or a medical-related property, since higher-hazard uses often call for a reduced pressure assembly. The plumber will confirm their certification and plan the visit.
Cost factors
- Pass or fail. A failure adds a rebuild and a retest.
- Assembly type. Reduced pressure assemblies, common on higher-hazard services, have more parts than double checks.
- Size. Large commercial and fire service assemblies take longer.
- Replacement. Cracked or outdated bodies are replaced.
- Permits. New installs may need a permit from the City of Loma Linda Building and Safety Division, which issues permits at its counter from 8:00 to 10:00 a.m. and takes online applications through its Citizen Self Service portal. City Hall is closed Fridays.
Local conditions in Loma Linda
The City provides water production, distribution and maintenance, with sign-up and billing handled by the Finance Department at (909) 799-2845. After-hours water, sewer and street emergencies go to (909) 356-3805. The City's backflow program, intervals and forms can vary by account, so confirm with the City before scheduling a test. Every California water supplier is required to protect its system from cross connections.
Loma Linda is built around Loma Linda University and its medical center, and medical, laboratory and campus buildings are classic places for high-hazard backflow protection. Residential neighborhoods, including Bryn Mawr on the east side, have a median home build year of about 1983, so many irrigation systems have older vacuum breakers that may leak once their seals harden. San Timoteo Creek runs through the city and has flooded parts of it in the past; an assembly that sat in floodwater should be inspected and tested before it is trusted again.
Short checklist
- Find the assembly and clear around it
- Have City letters and past reports ready
- Know your building or irrigation shutoff
- Warn occupants that water will be off briefly during the test
- Note any leaks or pressure changes
