Combination check valve/elbow

The Combination Check Valve and Elbow for Pentair Rainbow Chlorinator (R172061Z) is a replacement combination check valve with integral 90-degree elbow fitting for Pentair Rainbow automatic chlorinator installations. The check valve component prevents back-siphoning of concentrated chlorine solution into the pool plumbing suction side when the pump shuts off, protecting the pump and plumbing from chemical damage. The integral elbow simplifies installation by combining two components into one. Replace the check valve annually as preventive maintenance to ensure reliable back-flow prevention.
