Toro Check Valve for the 570Z Series

An elevation change as little as one foot can cause your irrigation system to drain through the lowest lying sprinklers in your yard. The Precision Check Valve (PCV) helps save water and prevents run off on sidewalks and street gutters by immediately closing – or checking – as soon as your irrigation system shuts off. Without the constant pressure of a running system, the stainless-steel spring in the PCV closes the valve and holds all of your system’s water in the pipes where it belongs. The PCV is made of high-strength plastic and easily screws into the bottom of all manufacturers’ ½” sprinklers.
