It’s Cold Outside!!! Here’s an easy guide on how to winterize your irrigation and sprinkler system, using the blowout method.

1. Turn Off the Water Supply
- First, shut off your main irrigation water valve. Look for it in the basement, garage, or a valve box.
2. Drain the System
- Turn on each separate zone before blowing out
- For a sprinkler blowout, connect an air compressor to the blowout port.
- Use about 50 PSI for PVC pipes or 30 PSI for polyethylene pipes to blow out each zone individually.
3. Winterize Backflow Preventer
- Drain and insulate back flow preventers or remove and store them if required by local codes. For outdoor installations, set ball valves at a 45° angle to prevent freezing.
4. Label System Parts
- Mark areas like valves, blowout ports, and manual drains so you can easily restart in the spring.
