Smart irrigation is crucial for the long-term success of your landscaping. A properly designed irrigation system will ensure that landscape water does not mix with drinking water. This will help prevent contamination. An irrigation system in Glendale, CA requires a back flow prevention device.

All about Back-flow Prevention

Glendale’s Uniform Plumbing code requires irrigation systems to be approved for back flow preventions. Back flow refers water flow that is reversed due to inadvertent actions. This can happen when water systems connect to irrigation methods. Back flow can lead to the release of harmful substances, such as herbicides, fertilizers and pesticides from the irrigation system in public drinking water supplies.

Back pressure and back siphonage are two possible causes of irrigation system low pressure. Back Pressure occurs when the pressure in the system exceeds that in the supply. These connections could increase the likelihood of back pain. Back Siphonage refers to water being pulled backwards because of a drop in pressure or an overall negative pressure on its water supply. Contaminated water could be drawn to the source using sprinklers or other emitters.

Glendale has many back-flow protection devices.

Atmospheric Vacuum Break: These valves provide maximum security and are available in manual or electronic forms.

They should be placed at the irrigation system’s facet at least six feet from the highest emission level. After being depressurized the floating disc will fall and allow air flow downstream.

A PVB: A pressure vacuum breaker is the next-level after AVB. The siphonage is prevented by a spring-loaded valve that opens when the water stops flowing.

Double check valve assembly. A DCV stands for double check valve assembly. It includes two spring-loaded devices. They are used to prevent back siphonage, back pressure on nonhazardous system and back pressure.

Low Pressure Assembly – This device can protect against both types of back flow. It can be used in high-hazard zones.
