The device itself ranges from $35 to $600, while professional labor costs between $100 and $400. Expect to pay between $70 and $250 for a backwater or check valve, including install. A single valve is easier to install than a comprehensive double-valve preventer system.
Do you need a vacuum breaker for sprinkler system?
A pressure-vacuum breaker is an important part of any irrigation system. It’s required by most cities because it prevents contamination of the potable water supply.
How does a PVB work?
How It Works. A pressure vacuum breaker consists of a check device, or check valve, and an air inlet that is vented to the atmosphere (open-air). When the air pressure is greater than the water pressure, the vented chamber opens and breaks the suction effect of the low pressure, thereby preventing the backflow of water …
What is an RP valve?
Reduced pressure zone assemblies (RPZ Valves) are extremely important. They’re used to keep contamination or pollution out of your water. Specifically, this device is installed onto your plumbing system to protect drinking water and the city water supply.
How often should a backflow preventer be tested?
How often does my backflow preventer need to be tested? Reduced Pressure Zone (RPZ) assembly needs to be tested annually and rebuilt every 5 years. Double Check Valve (DCV) assembly needs to be tested every 3 years.
Why do I need a backflow test?
Backflow testing is an important procedure to discover out how best to prevent contamination in your water supply. A proper test can identify the type and location of backflow preventer to help keep your fresh water clean.

How does a rain bird irrigation valve work?
Rain Bird’s electric valves are the gatekeepers of the system, opening and closing with a signal from the control box to supply water to the subterranean sprinkler pipes. The valves are powered by low-voltage wires running from the controller and do not require any specialized electrical knowledge to install.
How does an irrigation valve work?
Irrigation valves control the flow of water to the irrigation system. Each valve is responsible for one area, or zone, of the lawn irrigation system. Automatic irrigation valves work by electricity. Wires lead from the irrigation controller, or timer, to each of the the valves.
What is the pressure of a sprinkler system?
Water pressure is measured in pounds per square inch – also called psi. The average water pressure for most homes and businesses is between 30 psi and 50 psi; most sprinkler systems are designed to use pressures of around 30 psi.
What are the parts of a sprinkler system?
The average sprinkler system is simple in design and generally consists of four components: water supply, a control valve, distribution lines and sprinkler heads.
