Backflow preventer installation and certified annual testing for West Hollywood commercial and residential properties. Available 7 days a week. Call +1 (207) 419-2600.
Backflow prevention devices protect the public water supply from contamination by preventing water from flowing backward through the connection between a private property's plumbing and the municipal water main. When water pressure drops suddenly — due to a main break, firefighting demand, or pressure surge — backflow can allow potentially contaminated water from irrigation systems, industrial equipment, or other sources to enter the clean water supply.
Annual backflow testing is a compliance requirement for many commercial properties, irrigation systems, and multi-unit residential buildings in West Hollywood and Los Angeles County. A certified tester inspects the device, runs the required pressure differential tests, documents the results, and submits the test report to the local water authority. Failed devices must be repaired or replaced before the next annual testing cycle.

Backflow occurs when water flows backward from private plumbing into the municipal supply during pressure drops. This can introduce contaminants from irrigation or industrial equipment into the clean water supply.
Los Angeles County requires annual testing for commercial properties, properties with irrigation systems on municipal supply, medical facilities, restaurants, and other cross-connection risk properties.
It must be repaired or replaced before the next test cycle. The water authority is notified, and a failed or untested device on a required property can result in fines.
Standard testing takes 30–60 minutes. A certified test report is completed on-site and submitted to the local water authority.
Many failing components — seats, springs, rubber parts — can be rebuilt. Severely corroded or physically damaged assemblies are replaced entirely.
For irrigation systems, near the point where the irrigation supply branches from the domestic service line — often near the water meter or in a ground-level enclosure.
