Protecting Your Irrigation System From Winter Damage With Winterizing or “Blow out”

Your Simple Guide to Understanding Winterization or “Blow Out” of Your irrigation System

Before it’s October, when freezing temps are oftentimes in our forecast … I would recommend the time to call a professional for help with irrigation winterization is in early September! Get in the schedule before it’s too late!

Winterizing your sprinkler system—or what we call a “blow out” … is essentially removing water from the pipes, valves and sprinkler heads. It is critical to have an expert GreenWay Irrigation technician do this before any freezing occurs. After all, it’s the best way to protect your irrigation investment from sustaining serious damage over the winter. At GreenWay Irrigation, we utilize the “compressed air blow-out” method.
IMPORTANT! To use this method, your system must have been properly designed. If you’re a first time customer and we didn’t install your system, we’ll make sure your system is inspected before we attempt your winterization. Our GreenWay Irrigation technician will always use extreme care when blowing out your irrigation system, however, there are times when even the optimal precautions still aren’t enough and repairs will have to be done. Unfortunately, it’s a fact.

We are a professional irrigation contractor who is fully equipped to provide winterization for a competitive fee, which, oftentimes includes a Spring turn-on of your system. The value of utilizing our services comes from the fact we have been doing this for nearly 30 years … so we have much experience!

Do not try to use an air compressor with high pressure (120 psi) and low volume to evacuate water from the system by yourself. And I wouldn’t recommend compensating for a small compressor by filling the compressor’s holding tank while the mainline is closed to create a surge of pressure to blow the line clean when you open the sprinkler control valve. This dangerous practice will place very severe stresses on all components of your system. I’m just letting you know.

NOTE: Even if your system can withstand 120 psi of water pressure, similar air pressure will damage the system. The viscosity of air is much lower than water, it often generates much higher stresses.
