Tips on how to winterize your lawn
sprinkler system
3. Benefits of using Lawn Sprinkler Systems
Each winter your irrigation system will need to be “winterized” to prevent the
water lines from freezing and cracking. This involves blowing out the system with
compressed air and turning the main valve off to prevent water from flowing
back into the system and freezing.
4. Benefits of using Lawn Sprinkler Systems
Winterizing your lawn sprinkler system is very simple but has to be done in
proper way.
Turn Sprinkler system off
Turn off the water to the irrigation system at main valve.
Deactivate electronic controller(s) and all valves in the system
Drain all of the water out of the sprinkler system by air compressor
5. Benefits of using Lawn Sprinkler Systems
For the simple reason that even after you have drained water out of the system,
it is best to call a professional contractor for winterization due to, there could be
some water remains in the pipe that can freeze, expand and crack the PVC piping.
Polyethylene pipes are more flexible and can expand under pressure but, water
left inside could freeze and burst the pipe walls. Freezing water in the backflow
preventer will damage the internal mechanism.

Blow-out Method
It is recommended that a qualified licensed contractor performs a blow-out
method to winterize your lawn sprinkler system. Serious personal injury may
result if you do not proceed with care. One small mistake and you will no longer
own a lawn sprinkler system.
To winterize your lawn sprinkler system, you will need a commercial size air
compressor. You need to carefully attach the compressor to the mainline through
a quick coupler, hose bib or other type connection, which is located after the
backflow device. Shut off the irrigation water supply, close the compressor valve
then attach the air compressor hose to the fitting. Then slowly open the valve on
the compressor. The blow out pressure should NOT exceed 80 PSI.

You can start activating each zone from the furthest zone from the compressor
slowly working your way to the closest zone to the compressor. Keep each zone
activated until no water remains in the heads. Once the zone is dry, do not
continue to blow air through the pipe. Continuing to blow air through dry pipe
can damage.
Turn off the controller after you are done blowing out the system. You can install
the threaded caps over the open ends of the backflow preventer risers and any
blow out fittings to keep garbage out until spring. Store the backflow preventer
inside for the winter.
