Every valve plays an essential role in your house’s plumbing system. A mixing valve controls the mix of hot and cold water to provide a comfortable temperature. A check valve performs a vital function by preventing reverse flows, preventing damage, and ensuring efficient operations. A fill valve controls the water filling the holding tank, the part that opens the water flow as the flush cycle empties the tank and shuts off the water supply once the tank has refilled to the proper level. DK Hardware offers a variety of valves to meet all your household plumbing needs. The Taco mixing valve adjusts, maintains, and limits the hot water temperature settings to provide comfort and protect equipment at home. Designed to prevent scalding water and legionella bacteria growth by storing water at high temperatures.
