- Turn water
off going to the irrigation system from the meter or well tank.
This should be in the basement. If you can’t find it,
go outside of the house and find the vacuum breaker that is
on the end of the copper pipe that comes out of the house, (sometimes
this is by your air conditioner) and follow the pipe back into
- Hook up
the air hose to the plug on the copper pipe going into the ground,
on the water pipe coming out of the building.
- Turn on
the controller to zone 1 and set it to run
- Turn on
the air compressor and blow out each zone line until a mist
comes out. When all zones have been blown out, check each zone
again to make sure they are free of water.
- Turn off
air compressor with a zone running and let the air run down
before disconnecting the air hose.
- Turn the
valves on the V/B at an angle; half open so water will drain
out of behind the valves of the V/B. See V/B instructions.
- It is
recommended to turn the controller off but leave it plugged
in for the winter so as to keep moisture out of the controller.
You do not
have to have a lot of air pressure to blow a system out, but you
need a lot of volume. The small house compressors will work, but
sometimes they blow over the top of the water leaving water in
the lines. This will cause damage to the system.
any of the steps are done incorrectly, it may cause damage to
your system. Therefore, we recommend that it be done professionally.
