Sta-Rite MasterTemp Heater Manifold Assembly

Yes, this assembly is designed to fit both Sta-Rite MasterTemp and Pentair Max-E-Therm pool heater models. It serves as a direct replacement for the original manifold section on these units.

This is a comprehensive kit that includes the essential safety components, such as the high limit switch, thermistor, and water pressure switch. You will not need to purchase these sensors separately.

Replacing the entire assembly is often more efficient and reliable than piecing together individual components. It ensures that all seals, bypasses, and sensors are factory-matched and new, which helps prevent recurring leaks or sensor failures shortly after a repair.

While it is a straightforward swap, it does require basic plumbing and electrical knowledge to disconnect the heater, remove the old manifold, and install the new one. If you are not comfortable working with water lines and electrical sensors, we recommend hiring a pool technician to ensure the installation is leak-free and safe.

Common signs include persistent leaks around the manifold area, cracks in the plastic housing, or recurring errors related to the water pressure switch or high-limit sensors. If you notice water pooling under your heater or the system frequently shutting down due to sensor faults, a full manifold replacement is often the best solution.
