Polaris 360 In-Line Back-Up Valve

This Polaris in-line back-up valve is the current replacement valve for all years of the Polaris 360 cleaners. Check that the back-up valve is cycling properly. The back-up jet cycles on and off regularly. It should stay off longer than it stays on. There shouldn’t be any leaks from around the back-up jet. Check the housing for leaks, cracks, or damage.
