Quick Overview

The Rainbow HC-3315 High Capacity Chemical Feeder is extremely durable and highly reliable. Intended for 1-inch hard plumbing installations and works best with commercial applications. NSF listed and designed for trouble free sanitation of commercial swimming pools and spas.

This is an erosion type feeder designed for use with Tri-chlor tablets. The feeder works off the pressure side of the pump and discharges into the return line downstream of your equipment. The HC-3315 holds up to 15 pounds of tablets and treats up to 20,200 gallons with Bromine and up to 97,600 gallons with Tri-chlor tablets.

Pentair High Capacity Feeder Brochure


The INLET control valve side of the feeder connects to the plumbing on the discharge side of the pump, before the filter. The OUTLET side of the feeder connects to the pool return line after the filter and/or heater, pool cleaner, diverter valves, or any other installed equipment. Installation of a corrosion resistant check valve such as R172288 (sold separately) by Pentair between the feeder inlet and outlet and the equipment is strongly recommended to check back-flow of chemicals. This helps ensure equipment longevity.
