Abstract

A base connection device used to change a flapper drain valve to a barrel drain valve includes a flapper base and a first overflow pipe disposed in the external side of the flapper base; further includes a connection base and a second overflow pipe, the bottom of the connection base is sleeved on the flapper base in sealing way, and closing the bottom of the first overflow pipe, the top of the connection base is formed to a matching portion; the bottom of the second overflow pipe is connected to the outlet of the flapper base. To change a flapper drain valve to a barrel drain valve, the flapper base does not need to be disassembled. The barrel drain valve is inserted to the connection base to sleeve the connection base on the flapper base, with the second overflow pipe as an overflow pipe of the water tank.

Claims (14)
