Backflow Testing in Chino, CA

Local conditions

Chino runs its own water, sewer and storm drain systems, with accounts handled by the City's Utility Billing Services Division at 909-334-3264. That makes the City the place to ask about backflow, because rules for testing and reporting are set by the water supplier. State rules require every California water system to protect its pipes from cross connections, but the City sets its own specific intervals, forms and tester requirements, so ask the City about them before scheduling.

For permits, the City of Chino Development Services Department's Building Division at 13220 Central Avenue says nearly all construction or repair work requires a permit, with leaky faucet repairs listed as exempt. Installing or relocating a backflow assembly is new plumbing work, so expect a permit for that. For a water emergency outside business hours, the City asks residents to call the Chino Police Dispatch Center at 909-628-1234 so City staff can respond.

In most cities, commercial, landscape and fire services are where assemblies are most common, and a single-family home without irrigation or a second water source is less likely to be asked for one. The City can tell you where your property falls.

Repair, rebuild or replace

Signs to call

• A City notice asking for a backflow test or report
• Water spitting from the relief port when no fixtures are running
• Weak sprinkler pressure on zones downstream of the assembly
• Green crust or drips at test cocks, unions or shutoffs
• A property purchase with no test history recorded

Timing and seasonal notes

Summer irrigation puts the most strain on landscape assemblies, and a test scheduled in spring catches weak checks before the heat. Above-ground brass that sits in full sun can see seals age faster, so a simple insulated cover helps with both summer sun and the occasional frosty morning. If a test fails, ask the City how long you have to repair it so the retest fits the deadline.
