Wildomar is served by Elsinore Valley Municipal Water District, which requires backflow devices to be tested when installed and every year after, only by testers certified by the County of Riverside Department of Environmental Health. A device that fails must be repaired and retested within 15 days. Call the number on this page to be connected with a local plumber in Wildomar.

What happens when you call
This line is a free referral service rather than a plumbing company, and it connects you with an independent plumber who works in Wildomar. Tell them whether the notice came from EVMWD, what the device protects (landscape, commercial or agricultural service) and whether it has failed before. Ask early whether the person running the test holds the County of Riverside DEH certification EVMWD requires. A plumber can repair any assembly, but the official test has to come from a certified tester.
EVMWD allows 15 days to repair and retest a failed device, so it saves time to line up the fix while someone is already on site.
Cost factors
- Whether the device passes or needs parts and a retest
- Assembly type and size; a commercial service device is bigger than a landscape unit
- Full replacement if the body is cracked or the model is no longer supported
- Travel to hillside or rural parcels off Bundy Canyon Road or up in Sedco Hills
- Permit steps through the City of Wildomar's online portal if a device is added or moved
EVMWD rules in Wildomar
The City of Wildomar names EVMWD as its water and sewer provider. EVMWD runs a state-required Cross-Connection Control Program with clear rules: new commercial, industrial and landscape services get a backflow device installed immediately after the meter, and agricultural services often do too. The customer owns and maintains the device. EVMWD also says that once water passes through the meter, preventing contamination beyond that point is the property owner's responsibility.
Testing is required at installation and once a year after that, by a County of Riverside Department of Environmental Health certified tester. Program questions go to EVMWD's Water Protection Department at (951) 625-3404, and the district's main line is (951) 674-3146. Wildomar's median home was built in 1994, so many landscape devices have been in the ground long enough to need fresh seals.
Checklist before the visit
- Keep the EVMWD notice and account number nearby
- Clear brush, gravel or mulch away from the device
- Unlock any cage or box
- Let your household or staff know the water will be off for a little while
- Have earlier test results ready
