In Texas we don't have bad enough winters to necessitate full winterizations and blowouts, but that doesn't mean there aren't things that need to be done to keep your system from suffering damage on the few nights that we do see deep temperature drops. when you'd rather be safe than sorry, and spend your money on an ounce of prevention instead of a pound of cure, call our Grand Prairie sprinkler repair & winterization team.
Freezing temperatures, when they happen, mostly affect the surface level parts of your sprinkler system, but can also affect the piping. If there is ambient water in the system when the freeze hits, it can quickly expand and rupture or shatter pieces of your equipment. If you've ever left a can of Coke in the freezer, you know it's not pretty.
Once the system is compromised, you can expect water to leak out of your new holes, or for your equipment to cease to function. If the issue is not caught quickly, you could suffer subterranean leaks that will kill your lawn, noncoverage issues which will kill your lawn, or a slow ongoing water leak that can kill your wallet.
Freeze and rain sensors generally aren't damaged by freezing temperatures, but if water collects in them and then freezes it can still cause breakages. Covering these devices with plastic bags, insulating material, or even removing them altogether are popular ways of preventing damage.
The device you generally have to worry about is your backflow prevention device.The backflow contains unpressurized water, which is often a recipe for freeze damage. The device sits above the ground in an area that will often be exposed to the coldest temperatures.
Damage to your backflow can lead to a large, and possibly expensive, leak that will need to be fixed before the next time you run your system. Wrapping your backflow with insulation and a plastic bag can again be one easy way to prevent damage.
The best thing to do to keep your system in good condition is to keep tabs on the weather, or to speak with one of our irrigation techs. We can tell you how necessary it will be to prepare your system for the winter ahead, and give you a better idea what to expect from the service.
