I would like to know if the pressure vacuum breaker is suppose to be above the ground when installing the sprinkler system or is it buried in the ground. The only thing that i have is the control knob that is located in the garage. If so do i need to fix what i have ASAP before anything bad happens. Please help me!
Febco is one of the leading suppliers of back flows in the industry. Although the one you have maybe from another manufacturer you maybe able to find your answer by clicking on the following link http://www.febcoonline.com/products/default.asp?parCat=1134. There is an online company called http://www.HomeCenter.com that carries a large selection of their products as well as other irrigation items. Hope this helped.
