If I use city water, does winterizing my sprinkler system protect the main water line?
No. Blowing out your sprinkler system will not protect the main water line from freezing. Fortunately, if you are a customer of United Water, they offer a low-cost protection plan to cover the cost of repair or replacement should homeowners experience a leak in their main line. This service is known as LeakGuard and is available to most Treasure Valley residents. Please inquire about the availability in your area by calling 362-7304 or visiting www.leakguard.com.
