We offer late-season emergency lawn irrigation winterizing.
We can still winterize systems if the pipes or backflow have broken. 

Frozen Sprinklers System Can Be Saved!  Even if the pipes and backflow have frozen or even broken.  We can save all the inground systems till the frost sets in.  Meaning we can save the manifolds, inground valves, zones, heads, and drip systems.

Frost typically doesn't set in till the beginning of December.

Steps to try and prevent or minimize freeze damage to your sprinklers before we come and winterize them.

1. Turn on your system (Manually start watering all zones).  Water should be coming out of your sprinkler heads - if not it may be frozen.  You can wait up to 20 minutes and see if it unthaws or try during a warmer time of day when the temp is above 32 degrees.  Do Not Shut off The Sprinkler Control Timer, let it run through all zones.

2.  While the system is running. Shut off the inside water supply to your sprinkler system.  Once completed
you will see the water has stopped coming out of the sprinkler heads, do not turn off the sprinkler control timer and leave it running.

3. Open the faucet attached to your backflow preventer or remove the plug or cap (some water may spill out).  Do not turn off or unplug the sprinkler control timer and leave it running. 

 4. Turn the ball valves 45 degrees. (see photo below) Do not turn off the sprinkler control timer leave it running. Do not turn off the control panel and leave it running. 

 5. Turn the test cock valves 45 degrees with a straight slot screwdriver, you have to remove plastic black or yellow caps. Some you have to twist counter-clockwise to open. Do not turn off the sprinkler control timer leave it running.

When you're done the backflow preventer should look like this.

If you can't open the test cocks then, try to remove them with a wrench. If removed keep them handy for me when I come to blow out the system.

This will help protect the above-ground equipment and pipes, but this is not a complete winterizing of your system.

The in-ground portion will freeze as the frost sets in late November and damage may happen to your lines, heads, manifolds, and zone valves.

below please find a couple of links to videos to help and demonstrate systems that may be close to yours.  No two systems are the same.

So, use your own judgment as you try to drain the water from your exposed pipes.
