Product details

The Pentair Rainbow R172224X is the black drain and vent valve used on Rainbow equipment. It handles two jobs, bleeding trapped air out of the housing and draining it when the unit is opened for service.

Where it fits

Rainbow lists it for the Dynamic Series cartridge filters and for the High Capacity HC Series chemical feeders, which covers the HC-3315, HC-3330 and HC-3340 chlorinator models. Worth checking your parts diagram against the valve you are holding before ordering, since the two product families share it.

When to replace it

Vent valves are a routine wear item. Once the threads or the seal give up, the valve weeps whenever the system is under pressure. The o-ring for the Dynamic Series drain and vent valve is a separate part, so replace both if the old one has taken a set.
