Question
Hello, I have a Rainbird sprinkler system with Richdel 711A,
3/4 valves at my house.  Can you instruct me on how to drain/winterize my sprinkler system?  Your assistance is greatly appreciated.  Thank you!

Answer
Hey Roger, without actually seeing how the system was installed (drains, tee for blow out, automatic drains etc.) it would be hard for me to tell you exactly what to do. I would hate for the system to freeze and crack on you. What I would suggest, is have a company come out and hook up an air compressor to the system, and actually blow out all the water with compressed air. Most Companies only charge between $50.00 to $75.00 to have this done, and it is well worth the money. Good luck and have a great day.
