Product details

The Pentair 470190Z is the replacement pressure switch for Minimax pool heaters. It has a plastic body and it replaces the older Pentair 470190, which used a metal body.

What the switch does

A pool heater is not allowed to fire unless water is moving through it. The pressure switch is the device that proves that flow. It sits in the water path, senses pressure and closes a contact, and only then does the control let the burner light. If the switch fails open, the heater runs its start sequence and stops, usually with no obvious fault at the plumbing.

Before you order

Check the switch you are removing. If it is the metal body 470190, this plastic body part is its current replacement. It is listed for the Minimax Plus range, 150 to 400.
