Starting up your sprinkler system for the spring lawn watering season Should be done carefully and professionally Especially if your irrigation system was winterized and evacuated of all of the water in every zone.
A professional sprinkler repair service would first open the bleeder valve on each of the zones. This would require that you know where the irrigation valves are located.
Next, the Water main or the irrigation backflow control valve should be turned on slowly and carefully. Too much water pressure at one time where there is an abundance of air in the pipes can cause the pipes to rupture or the valves to break.
As the air escapes the sprinkler heads each zone should be turned off at the bleeder valve one at a time. The irrigation water main control valve can then be turned completely to the on position.
Doing a sprinkler system restart in the early spring can ensure that you get a jump on Properly maintaining your lawn. It also helps to identify if you have any problems with your system that May need to be scheduled by a professional sprinkler repair service.
