Question
Hello,I would like to know how to winterise my underground sprinkler system. I have a hunter system. I am pretty handy. thank you glenn hensonn

Answer
Hey Glenn, the best way is to have a tee with a cap installed on the main water line to the sprinkling system. In the winter when you shut off your main valve to the system, you will hook an air compressor up to this tee, and as the compressor builds up pressure, you will turn one valve on at a time, and this will push all the water out of the system through the heads. Every sprinkling system is different, so it is hard for me to tell you exactly what to do without physically looking at it. Hopefully this will give you a better idea. Good luck and have a great day.
