My Sprinklers have Lost Pressure
A common service call is for sprinklers that have lost pressure. Sometimes the answer is easily detectable and other times its less clear.
Some checks to do:
- Is it just one station or all of them? If its all of them then your master valve is most likely the problem.
- If its just one station can you see any puddles of water that indicate a leak? Another test is to locate the sprinklers and see if any of them are broken at the base or if any nozzles have dislodged.
- The third option is that the sprinklers are old, sticky and the nozzles blocked, giving an appearance of low pressure.
- The final possibility is that the solenoid valve has seized and is restricting flow.
Its just a matter of eliminating the simple options first and then going to the more complex.
