IPC: E03C1/12
Filed: 2010-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a drain connection pipe which brings about siphonage surely at a low cost.SOLUTION: In order to bring about siphonage in the inside of a drain connection pipe body 1, a retention part 3 is formed while keeping a space for a drain channel 2 and lowering a flow channel.
