Norco's water comes from the City's own water utility, so the City decides which properties need a backflow assembly and how tests are reported; ask the City for its program details. On horse properties, troughs and barn hookups are a common cross connection risk. Call the number on this page to be connected with a local plumber in Norco.
What happens when you call
You'll be connected with an independent plumber who works in Norco. Tell them what kind of property you have and what the device protects: a commercial service, irrigation, a fire line, or water lines running to a barn, arena or troughs. Describe any notice you received from the City and whether something is leaking. The plumber will confirm their tester certification and talk through whether a test, rebuild, new device or simpler hose bibb protection fits the job.
What affects cost
- Type of protection. A hose bibb vacuum breaker or air gap at a trough is simpler than a full assembly on a barn service.
- Test result. A failed device needs parts and a retest.
- Distance and digging. Lines to outbuildings can run a long way across a lot.
- Assembly size and type. Reduced pressure assemblies take more work than double checks.
- Permits. New devices or plumbing to outbuildings may need a permit from the City of Norco Building & Safety.
Local conditions in Norco
Norco is a semi-rural equestrian city known as Horsetown USA, with corrals, ranches and riding trails, and ordinances that protect animal-keeping. That shapes backflow here more than in most towns. A hose left sitting in a water trough, an automatic waterer with no air gap or a wash rack fed by a long hose can all let dirty water be pulled back into the home's supply if pressure drops. The fixes are well known: vacuum breakers on spigots, float valves set above the water line and, where a hazard calls for it, a tested assembly.
The City of Norco runs its own water system, serving about 26,000 people through about 7,500 connections. Most of its water is purchased desalted groundwater, largely from the Arlington Desalter, blended with water from City wells, and it's disinfected with chlorine. Hardness runs from 54 to 290 mg/L, averaging about 132. For the City's backflow intervals and forms, call Utility Billing at (951) 270-5654 or the Public Works Superintendent at (951) 270-5605 to confirm. Every California water supplier must guard against cross connections.

- Find the device, if there is one, and clear the area
- Know where the main and barn shutoffs are
