Draining Your System Using Blowout Method
This method requires using an air compressor with a CFM rating (CFM) while taking safety precautions such as using ANSI-approved safety eye protection. To begin the process, the water supply is turned off, and the air compressor is connected to the line fitting with the compressor valve closed.
On the controller, the zone with the sprinklers is turned on while the backflow isolation valves are closed.
Then, the compressor’s valve is kept open to gently allow air to enter the irrigation system.
Throughout the procedure, the blowout pressure must not exceed 80 PSI and should remain below the rated maximum pressure limit of the lowest pressure permitted component on that zone.
Draining Your System Manually
The manual method is effective when a sprinkler system’s manual valves are positioned at the end of low points of the irrigation piping. The process involves disconnecting your water supply and activating all manual drain valves. After that, the boiler drain valve on the stop and waste valve is then opened to drain any residual water between the irrigation water shut-off valve and the backflow device.
Some systems have automated components that drain the water when the main valve is shut off.
