Can a sprinkler valve cause 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.
How do I increase the water pressure in my pop up sprinklers?
Adjust the pressure regulating dial on your control module.
If the pressure is a little low, try turning this dial to increase the pressure manually. For a fixed spray system, aim for 20-30 psi per sprinkler. On a rotor/pop-up system, shoot for 30-60 psi. Irrigation and drip systems require 20-40 psi.

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.
Why does one of my sprinkler zones have no pressure?
Often when your sprinkler system was running fine, and then one zone began to lose water pressure, the culprit is a leak in the zone’s lines or a leak at a nozzle or two. Leaking nozzles won’t produce the same water pressure and need to be replaced, which is fairly simple.

Are sprinkler valves supposed to leak?
Sprinkler valve leaks are important to address because even the smallest leak will waste more water – and more money – every day that the leak goes unattended. When there doesn’t seem to be any visible damage to the sprinkler head, then damage to the valve seal is likely the culprit.
