Manually controlled valves are the most popular choice for irrigation systems. There are three main types: gate valves, ball valves, and electric valves. Gate and ball valves are manual and can be used if you don't plan to automate your system. This valve isolates the irrigation system from the main water supply when closed.
When open, it allows water from the main supply line to enter the irrigation system. It is usually located underground near the meter in an in-line system, or inside or above the ground near the point where the main water line leaves a structure in an aboveground system. A backflow prevention device is also essential for any lawn sprinkler system. It prevents water that has entered the irrigation system from returning to the drinking water system.
This unit should always be downstream of the isolation valve. It opens the automatic valves of the lawn sprinkler system when activated by the system controller. Sprinkler systems make it easy to keep your garden looking vibrant during long, hot summers and droughts. In large systems, integrated pressure regulators may be necessary to maintain water pressure. Purging is a process used to remove water from the system for routine maintenance and repairs.
Sprinkler valves can also be used to shut down the system in case of emergency and prepare it for winter. Before installing your sprinkler system, it is important to check local laws and regulations as they may dictate what types of valves and backflow prevention devices you can or cannot (or should) use. Installing a lawn sprinkler system can be a great way to keep your garden looking healthy and vibrant all year round. With a few simple steps, you can ensure that your sprinkler system is properly equipped with the right valves and backflow prevention devices for optimal performance.
