Local conditions in Valley Center

Valley Center is a rural community with deep agricultural roots that is slowly shifting toward a mix of homes and businesses. Valley Center Municipal Water District serves about 29,938 customers across a service area of more than 56,000 acres, and its water quality report says the district runs an active backflow prevention program protecting the public supply from the customer's side of the meter. How often devices are tested, who may test them and how reports are filed were not spelled out in what we reviewed. Call the district's main line, (760) 735-4500, which also takes problem reports at any hour, to ask what applies to your account.

Agricultural irrigation is the classic backflow hazard. A grove system that injects fertilizer can push contaminated water toward the meter during a pressure drop, which is why these services almost always get a tested assembly. Large residential lots with extensive landscaping fall into the same category. District water is chloraminated imported supply, and the report lists different hardness levels for its source plants, so mineral buildup on internal parts is possible.

Valley Center is unincorporated, so new plumbing work goes through the County of San Diego Planning & Development Services Building Division. Inland nights get cold enough that outdoor assemblies need freeze protection.

What changes the price

• How many assemblies serve the house, grove and outbuildings
• Size, which can be larger on agricultural meters
• Rebuild parts or a new assembly after a failure
• Travel and the time to locate the device on a large parcel
• County permit for a new device or rerouted line

What happens when you call

An independent plumber who works in Valley Center takes the request. Describe the property, what the device protects and any notice you have received from the district. If an assembly is leaking hard, shut the irrigation valve or the main until the visit.
