This Weil-McLain Fill-Trol Tank is a vital component designed for use in heating systems. The product, also known as the 109 GV model, is part of the company's well-regarded line of hydronic heating equipment. The Fill-Trol Tank functions to maintain system pressure and ensure consistent water levels within the boiler system. It features a pre-charged air bladder that provides a cushion of air for the heated water to expand into, preventing dangerous pressure build-ups. This tank is compatible with Weil-McLain's GV Boilers and is constructed from robust materials to ensure durability and longevity in demanding heating environments.
