Introduction

Before replacing the cartridge, first check a nearby faucet or shower to see if it is also getting inconsistent water temperature. If it is not, then the problem would be the valve’s cartridge and would need to be replaced.

This guide will take you through the steps of replacing the cartridge of a Moen Posi-Temp shower valve.

This procedure will take you through the plumbing so make sure that you locate the main shutoff valve to the shower or to the house as you would need to turn off the water for this procedure.
