Dear Customer:

Thank you for scheduling your sprinkler system winterization with the Sprinkler Doctor, a division of Sage Solutions Inc. 

Our winterization process utilizes a powerful gas-powered air compressor to push all the water out of each zone as well as to the basement bleed valve. We invite you to observe the process while we are there.

In rare cases, customers will find freeze damage in the spring. There are only two possible causes of freeze damage after the winterization process. They are as follows: 

  1. Someone inadvertently turned the basement shut-off valve on during the winter, which refilled the system.
  2. The main shut-off to the sprinkler system in the basement has a slow leak that slowly refills the system over time. We refer to this as a “weeping ball valve.” You can detect this problem by inspecting the backflow during the winter periodically. There should be no signs of water coming from the testcocks. 

Our winterization warranty is that we correctly removed the water from the system during service. Due to the aforementioned possible problems, we do not guarantee that your system will remain free of water all winter long. 

Please note that problems like this are infrequent but can happen. If your system has a history of freeze damage after winterizing, you should hire a licensed plumber to replace the sprinkler system’s main shut-off valve inside your house. 

We appreciate your business and look forward to serving you soon. Please feel free to contact us at any time.
