Why do you need a backflow preventer?

Backflow Preventer assemblies are designed to prevent contaminated water from mixing into clean municipal water supplies, which are usually used as drinking water. Contaminants like sediments, bacteria, and fertilizer are a major public health hazard, so in most all states, there are regulations in place that require certain buildings to have backflow preventers installed.

What is backflow testing and when does it occur?

What is backflow testing and when does it occur?
Backflow testing evaluates a plumbing system to see if backflow is occurring. In backflow testing, our certified plumbers assess how well your backflow preventers are working. Backflow preventers are devices within the plumbing system that keep the flow of water moving in the proper direction. They act as barriers to prevent harmful contaminants from entering a community's potable water supply.
Backflow occurs when water reverses course and begins to flow in the wrong direction. There are two main reasons backflow can occur:

  • Back siphonage: Back siphonage occurs when water changes direction because of a drop in water pressure. It most commonly takes place because of a water main break.
  • Backpressure: Backpressure occurs not because of a drop in water pressure but because of an increase in water pressure - imagine blowing through the straw and pushing water back into the glass instead. It happens when the downstream pressure in a water supply is higher than the pressure at the water source.
