排水トラツプ。 A drainage trap chamber through which excessively expanded water released from a relief valve attached to a closed water heater is passed and drained, a backflow prevention device installed downstream of this trap chamber, and a backflow prevention device installed in the backflow prevention device. The drainage trap chamber is made up of a water seal standard water level holding part placed on the downstream side, and is formed to take in the excess expansion water, and communicates the bottom part with the upstream side of the backflow waterproofing device to prevent backflow. The prevention device is arranged with its upstream side facing down and its downstream side facing up, and is formed so that the downstream side can be closed and the flow hole of the expanded water can be closed by a sphere whose specific gravity is slightly larger than that of water. The water seal standard water level holding part is a conduit that can be connected to a drainage equipment such as a washbasin drainage pipe or a sink drainage pipe, and the backflow prevention device is installed at a height below the upper limit water level of the drainage trap chamber. A backflow prevention system characterized by being formed of a standard water level securing pipe connected to the downstream side and a drainage pipe connected and extended to this pipe, bent to the side, and discharging the water to the drainage equipment. Drainage trap with device.
