Lawn Irrigation System Backflow Preventers

Irrigation backflow devices are important to your irrigation systems as they prevent toxic and non-toxic elements from entering your water. At Sierra Irrigation we provide high quality, low cost, top brand backflow preventers, that include manufacturers such as Watts, Wilkins, Champion, and Febco Backflow Preventers.
How does using an irrigation backflow device protect your home from contamination and pollution? By preventing the water from reversing its flow and siphoning back into the potable water system. In many areas, rpz backflow preventers are required by the City to protect the area water quality.

How to Install a Backflow Preventer

Installing a reduced pressure backflow preventer device by yourself can be challenging; it may take a little pre-education about backflow preventers before you are able to successfully install your own device. To be safe, follow these guidelines before attempting to install your backflow prevention device yourself: Obtain a list of code requirements (depth of the pipe, dimensions of the backflow preventer box, installation heights, etc.) from your local building code permit office or water utility supplier

Turn off your water supply
Cut into the water line
Attach smaller pipes (to create zones) to the main water line
Install a shut-off valve below the service line.
Thread the backflow preventer onto the main line and tighten it with a pipe wrench
Thread the master control valve onto the other end of the backflow preventer using a stainless-steel clamp.
Crimp the clamp tightly and slide clamps onto the main pipe and zone pipes.
Slide a T-coupler into the main pipe and zone pipes and onto the control-valve pipe.
Crimp all clamps down; use two clamps per section for the best results.

In addition to purchasing a reduced-pressure assembly or pressure vacuum breaker assembly, you will need a line of copper pipe. However, PVC pipe for backflow preventers can be used in non-freezing areas as a line into the main water supply. At Sierra Irrigation, our experienced staff can advise you on the steps to take when performing a backflow preventer install.
