Most sprinkler systems have a back flow preventer installed, and it is a very important part of your system to understand. It is above ground making it susceptible to freeze damage which could result in expensive repairs or even water damage. It is also a quick and convenient location to shut the water off to your sprinklers in case of a mainline break without having climb your crawl space.
If you don't have a back flow preventer, you should. It protects outside contaminants from accidentally entering your drinking water. Call or email us today if you would like more information.
