The water manifold are the distribution and water collection devices used to connect the water supply and return water of various heating pipes in the water system. The water manifold used in the floor heating and air conditioning system should be made of brass, and the water manifold used in the renovation of the household surface of the tap water supply system is mostly made of PP or PE. Both supply and return water are equipped with exhaust valves, and many water manifolds are also equipped with drain valves for supply and return water, and a "Y" type filter should be installed at the front end of the water supply. Valves should be installed in each branch of the water supply pipe to adjust the water volume. In the floor heating system, the water manifold is mainly responsible for the opening and closing of the water flow in the floor heating loop. When the water in the gas boiler flows into the water manifold through the main pipe, the impurities are isolated by the filter, and then the water is evenly distributed to the loop. After heat exchange, it returns to the water collection back to the main bar, and then flows into the heating system from the water return port.
