The balancing spool ensures consistent water temperature by equalizing the pressure of the incoming hot and cold water supplies. A stuck or faulty spool can lead to problems controlling water temperature or result in only hot or cold water flow.
It is designed specifically for use with Moen Moentrol single-handle tub and shower faucets and valves (e.g., models 3150, 3170, 3175, and 3189). It replaces OEM part number 132343.
