Backflow Prevention

What is Backflow Prevention?

We all value (and often take for granted) the purity of our water systems. Essentially, a backflow preventer  prevents toxic substances (chemicals, animal feces, petrocarbons, etc.) from entering our local water systems. Every irrigation system is required to have a backflow preventer installed. Each local water district or purveyor has different rules and regulations about types and standards required for an irrigation system.

The most common types of backflow preventers:

  • Reduce Pressure Principle Device (RP)
  • Double Check Assembly (DC)
  • Atmospheric Vacuum Breaker (AVB)
  • Pressure Vacuum Breaker (SVB)

Why should you care?

I assume you don’t want your neighbor’s dog poop in your drinking water. You should recommend that they get their back flow preventer tested (and you should get yours tested as well). Backflow preventers need to be tested periodically to ensure they are working properly. Every area has slightly different rules about the types of backflow preventers required and how often they must be tested. Additionally, there are regulations about reporting.


What we can do

We can test, repair and even replace backflow prevention systems. Give us a call!
