What causes a sprinkler zone to have low pressure?
The most common cause of low water pressure in sprinklers is the backflow preventer valves not opening fully. There are two main pipes in your backflow preventer – one horizontal and one vertical. Each pipe has a handle that can be turned to run with the line or across to open the valve.
