Product Overview
Upgrade an existing Pentair IntelliChem chemical container to Pentair’s newer tank-mounted chemical pump configuration with the Pentair 522474 IntelliChem Tank Pump Upgrade Kit.
This genuine Pentair upgrade kit is designed specifically for older IntelliChem chemical containers that were originally supplied without an integrated pump. Pentair identifies this kit as the upgrade solution for IntelliChem container models 521378 and 521397, allowing the existing tank to be converted for use with the newer tank-mounted pump system.
The tank-mounted pump arrangement provides a compact installation directly at the chemical container, helping simplify the chemical-feed system and reduce the need for a separately mounted external feed pump. It is designed for IntelliChem installations used to automatically manage pool-water chemistry through controlled chemical dosing.
For service professionals upgrading an older IntelliChem installation, the 522474 provides an OEM Pentair solution rather than requiring replacement of the entire chemical storage container.

Pentair specifically lists part 522474 as the upgrade kit for converting older non-pump IntelliChem containers 521378 and 521397 to the newer tank-mounted pump design.
Installation & Upgrade Information
During installation, the existing IntelliChem chemical container must be properly secured to the equipment pad and positioned within the required distance of the IntelliChem controller.
Pentair's installation instructions call for removal of the existing tank block-off plate, installation of the motor shroud, mounting of the pump assembly, and connection of the chemical-feed tubing between the tank, pump, and injection point. The injection fitting is installed in the pool return plumbing downstream of the other equipment.
Pentair recommends that the chemical container be located within approximately 10 feet of the IntelliChem controller and positioned away from equipment that may be damaged by chemical fumes or accidental chemical exposure.
Important Compatibility Note
522474 upgrades the chemical container/tank.
It should not be confused with Pentair 522478Z, which Pentair identifies as the IntelliChem motor-driver/tank-pump PCBA upgrade kit used on the controller side of the system.
Some older IntelliChem installations may therefore require additional controller-side components depending on the existing configuration.
Frequently Asked Questions
What does Pentair 522474 do?
The 522474 kit converts compatible older IntelliChem chemical containers that do not have a built-in pump to Pentair's newer tank-mounted pump configuration.
Which IntelliChem tanks are compatible?
Pentair specifically identifies the 521378 acid container and 521397 chlorine container as compatible older non-pump containers that can be upgraded using part 522474.
Is 522474 the same as 522478Z?
No. 522474 is the upgrade kit for the IntelliChem chemical tank/pump assembly. 522478Z is a separate upgrade kit associated with the IntelliChem controller and tank-pump motor-driver PCBA.
Can this be used for acid or chlorine applications?
Pentair identifies both its older acid container 521378 and chlorine container 521397 as compatible with the 522474 tank-pump upgrade. Chemical-system configuration and installation must follow Pentair's instructions.
Does the whole IntelliChem tank need to be replaced?
Not necessarily. The purpose of the 522474 kit is to allow compatible existing IntelliChem containers to be upgraded rather than replacing the complete container assembly.
Professional Installation Recommended
Chemical feed systems handle concentrated pool chemicals and require correct tubing, injection-point placement, electrical connections, and chemical-handling procedures.
Pool Supply Depot recommends installation and servicing by a qualified pool professional familiar with Pentair IntelliChem systems.
Always verify the existing IntelliChem container and controller configuration before ordering, particularly on older installations where additional controller-side upgrades may be required.
