Pentair Sta-Rite Max-E-Therm & Mastertemp Heater Manifold

This manifold is designed as a direct replacement for specific models within the MasterTemp and Max-E-Therm lines. It is best to verify your heater's specific model number against the manufacturer code 77707-0015 to ensure a precise fit.

The most common indicators are visible water leaks around the manifold assembly, cracks in the plastic housing, or a noticeable drop in water pressure within the heater. If you notice water pooling under the unit, the manifold is often the first component to inspect.

If you are comfortable with basic plumbing and pool equipment maintenance, this is a manageable DIY project. However, because it involves the heater's water circulation system, ensure the power and water supply are completely shut off before beginning, and consult your heater's manual for specific installation steps.

This manifold is typically sold as the housing unit itself. We recommend checking your existing hardware to see if the O-rings are still in good condition, though it is standard practice to replace old gaskets with new ones during this repair to prevent future leaks.

Using an OEM part ensures that the dimensions, material quality, and pressure tolerances match the original design of your heater. This guarantees a secure, leak-free fit and maintains the integrity of your heater's water flow system, which aftermarket alternatives may not always replicate.
