Product Overview

The Pentair 471441 Bulkhead Adapter is a service replacement part used in the water connection assembly of compatible MiniMax heaters. Its primary role is to provide a stable 2 inch connection point within the heater plumbing system so water can move through the unit correctly during operation. Because heater plumbing components are exposed to water pressure, heat, and long-term equipment wear, the bulkhead adapter is an important part of maintaining a secure and properly sealed system.

This part is well suited for repair situations where the heater remains otherwise serviceable but the original adapter has become damaged or no longer seals correctly. It is commonly tied to MiniMax heater models in the 200 through 400 range, making it a model-family-specific water system part rather than a universal plumbing fitting. For pool and spa service professionals maintaining compatible MiniMax heaters, the 471441 fills an important role in restoring proper water connection integrity and dependable heater performance.
