Spring Irrigation Sprinkler
System Startup and Winterization
System Winterization is
a topic that often comes up just before some of the coldest days of
the year. Homeowner's that don't employ a regular lawn
maintenance service all year (who would otherwise keep up with this) come to realize that their sprinkler
system's water pipes may be in danger of freezing if they are not
fear is definitely true in "The North", where sustained lows will
definitely freeze pipes, even if they are buried underground.
Florida for instance, there is no fear of burst pipes because there
are usually no sustained lows that would cause a problem.
Here in Lexington, S.C., it is debatable whether or not you need to
winterize your sprinkler system. Generally speaking, if the
pvc pipes were properly installed, burying them deep enough to avoid
freezing, there is probably nothing to worry about.
If you do want to be sure though, evacuating all of the pipes and
valves of all of the water can be done by blowing the system out
with compressed air. Alternately, draining the system can be
done by gravity if there is a low spot on the system that could be
opened to allow the water to flow out.
Starting the system up in the spring, you have to be careful to open
the valves slowly, allowing the system to fill with water without
damaging the pipes, valves, or heads. This should be done by
using the valve's bleeder screw, one zone at a time. Once all
the air has been forced from the system, you can then
set the sprinkler head spray pattern if need be and enjoy a well
