These should be installed adjacent to your point of connection with the water supply. Its purpose is to enable you to operate on the mainline or irrigation valves without disrupting the supply of water to your home. There are two basic types for you to choose from: The Gate Valve and The Ball Valve. The Ball Valve is more expensive, but it typically lasts for longer periods of time.
These devices are used to turn a sprinkler system either on or off. Though manual valves are available, most modern systems include valves that are connected to a controller for automatic operation. We offer three different types of control valves: a globe valve, an angle valve, and an anti-siphon valve.
IMPORTANT: A BACKFLOW PREVENTER MUST BE BOUGHT OR PROVIDED SEPARATELY TO COMPLETE THE PROPER INSTALLATION OF A GLOBE OR ANGLE VALVE. IF YOU PURCHASE AN ANTI-SIPHON VALVE, THE BACKFLOW PREVENTER IS ALREADY BUILT-IN AND AN ADDITIONAL ONE IS NOT NECESSARY.
Commonly purchased for use in commercial irrigation systems. It is typically installed beneath the ground, and to your convenience, is available in almost any size. They are relatively cheaper than the angle and anti-siphon valves. A backflow preventer MUST be bought or provided separately.
Offers the same features as the aforementioned Globe Valve but is constructed with an additional inlet at the base of the valve. This creates a 90-degree angle between the inlet and outlet pipes, a construction that moderates the pressure drop that may occur across the valve. If this is indeed a concern for you, the angle valve is a better choice than the globe valve. Again, a backflow preventer MUST be bought or provided separately.
This is quickly becoming the most popular choice amongst consumers, especially since some building codes are beginning to require their installation in irrigation systems. The function of this particular item is best explained by describing the problem it solves: -The Siphon Effect-. The backflow preventer is already built in.
