Sprinkler Blowout and Winterizing

Sprinkler systems require minimal maintenance but winterizing is not one you should overlook.  Blowing out your sprinkler system in the fall is essential to keep your pipes from freezing and cracking. We recommend scheduling your fall sprinkler blowout early to avoid the last-minute rush when a freeze warning takes effect.

Our Fall blowout and winterize program usually cost around $75 and can prevent costly repairs

 

What’s included?

  • A check of your system for leaks, damage, and wear and tear
  • Shut off the main water supply to the system
  • Shut off the timer or controller for the system
  • Drain all water lines, including manifold
  • Run compressed air through each zone valve to displace all the water from the line.  This is the most important part of winterizing.  Without it, your pipes could freeze and require replacement.

 

A typical Sprinkler System Maintenance Schedule looks like this

  • Activate your system in the spring (after the last freeze).  Start and check each zone and head for correct spray pattern and water pressure.  Also set/check timer controller schedule for the season and any mandated water restrictions or watering guidelines.
  • Mid season, re-check each zone and sprinkler head for spray pattern, water pressure, and leaks.  Also, make any adjustments to your timer controller for seasonal changes as well as potential changes in water restrictions.
  • Winterize your system at the end of the season – before the first chance of a freeze.  Inspect system for damage.  Have a professional sprinkler technician, like JRM, blow out the water in your system.  This is typically done a zone at a time with an industrial (most are truck based) air compressor.  With the correct equipment and expertise, the air will force all the water out of each line to prevent it from freezing over the winter.  Frozen irrigation lines can rupture as the water expands and form cracks in the pipes.  This can be a costly repair when it comes time to start up your system in the spring.  This type of repair requires finding the leak and digging up the dirt to replace the damaged line(s).

 

A properly maintained system will also prevent water waste.

Here are some common reasons how a sprinklers system can waste water.

  • Excess runoff from improperly directed or damaged spray nozzles.
  • Leaks in the valves and control manifold.
  • Cracks in pipes and underground irrigation lines.
  • Improperly set zone timers that oversaturate a particular area.
