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

Frozen Sprinklers System Can Be Saved!  Please try and follow the instructions below.

If you still need sprinkler system winterizing we can perform that service until the frost sets in typically in late November, even if the pipes outside have frozen and even broken.  

Steps to try and prevent freeze damages to your sprinklers.

1. Turn on your system (Manual 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.
You will see nothing coming out of the sprinkler heads, do not turn off the sprinkler control timer leave it running.

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

 5. Turn the test cock valves 45 degrees with a straight slot screwdriver, some 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 it the back flow 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.

Here is 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.
