A sprinkler manifold consists of two or more valves, and each valve controls one station within the sprinkler system. Adapters, Swivels, and Caps – When it comes to a sprinkler system manifold, no arrangement would be complete without adapters, swivels, and caps.
How does a sprinkler manifold work?
There are many types of irrigation valves. The controller sends a signal to the solenoid which then opens or closes the valve. One side of the valve connects to the manifold; this is known as the inlet. The inlet will be under constant pressure and allows water to pass through only when opened by the controller.

Can a bad sprinkler valve cause low pressure?
One of the leading reasons for low sprinkler water pressure relates to the valves on your backflow preventer device. If you notice limited water pressure in your sprinkler system but normal water pressure inside your home, then the problem might be that your backflow preventer valves are not completely open.
When should you replace sprinkler valves?

The anti-siphon valve must also be above ground. You can put a box over it to hide it, but it must be above the ground level.
Is anti-siphon the same as backflow preventer?
An atmospheric vacuum breaker, also known as an anti-siphon valve, stops back siphonage with a floating disc. AVB’s can be plastic or brass and either manual or electric. Unlike other backflow preventers, AVBs are installed on each zone of the irrigation system, immediately after the zone control valve.

What is a master valve on a sprinkler system?
A master valve is a “normally closed” valve installed at the supply point of the main line that opens only when the controller initiates a watering program. Whenever one of the irrigation zone valves is told to open by the controller, the controller also signals the master valve to open.
