This service part supports reliable repairs on Purex systems, helping maintain existing equipment instead of replacing a larger assembly. The drain valve is used on Minimax 100 1/4" Drain Valve applications and provides a controlled drain point for heater service, winterizing, or maintenance. It is a useful replacement when the existing part is cracked, corroded, stripped, distorted, leaking, missing, or no longer holding the correct operating position.Keeping the original assembly serviceable can reduce downtime, avoid unnecessary equipment replacement, and preserve the existing plumbing layout. This part is best suited for precise repairs where the matching OEM-style part number, 72136, is the main guide for compatibility. Inspect neighboring seals, fasteners, and mating surfaces during service because related wear can affect the final repair.
