This utility model discloses an improved direct-connection pump house, including a pump house body. Two sets of water pumps are installed within the pump house body. One end of each set of water pumps is connected to a flanged butterfly valve (fourth type). One end of the flanged butterfly valve (fourth type) is connected to a connecting pipe. The free end of the connecting pipe is connected to a water pipe (first type). The right end of the water pipe (first type) is connected to a Y-type filter. The right end of the Y-type filter is connected to a flanged butterfly valve (first type). The right end of the flanged butterfly valve (first type) is connected to a sanitary pipe (first type). The other ends of the two sets of water pumps are connected to a connecting elbow. A check valve is connected to the top of the connecting elbow. This utility model, through a dual-pump parallel architecture, switches between pumps in case of a single pump failure, ensuring continuous water supply. Independent control is achieved through the connecting pipe and the flanged butterfly valve (fourth type). The sanitary stainless steel piping of water pipe (first type), water pipe (second type), sanitary pipe (second type), and sanitary pipe (first type) in conjunction with the Y-type filter ensures clean water delivery.
