What backflow preventer do I need for irrigation system?
What backflow preventer do I need for irrigation system?
The three most widely approved and used backflow devices are the pressure vacuum breaker assembly, the double check valve assembly, and the reduced pressure zone assembly. All three of these types are installed immediately after the irrigation system isolation valve to protect the entire irrigation system.
How does an irrigation backflow preventer work?
Backflow prevention systems are devices installed onto a pipe that only allow water to flow in one direction. Think of it as a one-way gate that allows water from the city’s public water supply to flow into your home’s piping but stops water if and when it ever tries to flow backwards into the main water supply.
Where does irrigation backflow preventer go?
Irrigation backflow preventer devices are designed for installation on potable water lines to protect against both back-siphonage and back-pressure of contaminated water from sprinkler systems into the potable water supply. Backflow assemblies provide protection where potential health hazards exist.
What does a backflow preventer device do?
Do You Need a Backflow Preventer? Backflow preventers are devices that are installed on your home’s water pipes that only allow water to flow in one direction and not the opposite. Their purpose is to prevent drinking water from being contaminated with other sources because of backflow.
Do I need a check valve on my irrigation system?
Without check valves built into the body of the sprinkler, water leaks out of the lowest sprinkler in a zone. Check valves prevent this type of drainage from happening. Sprinkler head check valves also help to conserve the amount of water needed to fill the pipes each time the sprinklers begin running.
What is the difference between a check valve and a backflow preventer?
Check valves use a hinged plug that allows water to pass through the pipeline but blocks it from coming back. Backflow preventers, on the other hand, apply an increased amount of pressure on a pipe to ensure the water can only flow one way.
