Smart irrigation is essential for the long-term health and well-being of your landscaping. Properly designed irrigation systems will prevent landscaping water from mixing with drinking water. This will reduce the risk of contamination.

If you have an irrigation system, it is important to have a back-flow preventer installed in Long Beach.

All about Back-flow Prevention

According to the Uniform Plumbing Code, irrigation systems must be approved for back-flow preventions. These devices protect Long Beach’s water supply from contamination.

Back flow is water flow that has been reversed by inadvertent actions. Back flow occurs when water systems are connected with irrigation methods. Back-flow can result in the release of herbicides, fertilers, or other harmful substances from the irrigation system into public water supplies. Back-pressure or back siphonage can cause irrigation system back-flow.

Back pressure is when the system pressure exceeds the supply. These connections can increase your risk of experiencing back pain. Back siphonage is when water is pulled backwards due to a decrease or overall negative pressure on the water supply side. This could result in contaminated water being drawn from the source by sprinklers or other emitters.

Long Beach, CA has a number of back-flow prevention devices.

Atmospheric vacuum breaks: These valves offer the highest level security and can be purchased in either manual or electrical forms.

The floating discs should be placed at least six inches from the highest emission stage of the irrigation system’s facet. The floating disc will eventually collapse when it is depressurized and air can flow downstream.

A PVB is the next level from AVB. It prevents siphonage using a spring-loaded check valve that opens when water stops flow. If pressure falls below 1 psi, an air relief valve can be used to stop the siphon breaking.

Double check valve assembly. Double check valve assembly. A DCV is also known as a double-check valve assembly. Two spring-loaded check devices are included in this double check valve assembly. These devices prevent back siphonage as well as back pressure on non-hazardous systems.

Low pressure assembly. This device protects against both types of back flow and can be used at high-hazard locations.
