Pentair ETi 250 Condensate Neutralizer Replacement Kit | 476375Z

The Pentair ETi 250 Condensate Neutralizer Replacement Kit (476375Z) is a service part designed for the Pentair ETi 250 Series Pool & Spa Heater. This kit replaces the media-filled neutralizer used to treat acidic condensate created during combustion, helping protect drains and plumbing from corrosion by raising the pH of condensate before it exits your system.

What This Part Is For

This condensate neutralizer replacement kit is specifically for use with the Pentair ETi 250 Condensing Heater. It’s intended to replace spent neutralizer media and components that no longer effectively balance acidic condensate, which is especially important where local codes require neutralization prior to drain discharge.

Features & Benefits

  • Replacement kit for ETi 250 condensate neutralizer assembly
  • Helps raise pH of acidic condensate to meet code and protect plumbing
  • Includes media and components designed to OEM specifications
  • Essential for seasonal service or after media exhaustion

Installation Notes

  • Turn off heater and power before servicing the condensate neutralizer
  • Follow manufacturer instructions for safe removal of old neutralizer media
  • Install replacement media and components, securing all fittings and seals
  • Test condensate flow and check for leaks before returning the heater to service

Maintenance Tips

  • Inspect neutralizer media periodically for depletion or discoloration
  • Replace according to your heater usage and local code requirements
  • Keep condensate lines clear of debris to help maintain proper flow
