    See all 3 items in product family
    Taco® Tank Drainers Provide Effective Air Control In Hydronic Systems.

    Tank fittings maintain adequate air cushion to provide sufficient pressurization against all fluctuations of water volume. Tank drains maintain collected air within the pressure tank and allows air to pass freely into the tank. Restricts gravity flow of water between the tank and the system, resulting in lower tank temperature that minimizes re-absorption of air. Includes a single handle shut-off.
