Removal method of water tank plug: 1. Press the plug of the sink with your fingers to make the plug stand up, then hold the stand-up side of the plug with a wrench and pull it out hard.
2. After turning the plug of the washbasin upside down, we put a rope through the hole on one side of the plug and then through the hole on the other side of the plug. Everyone grabs both ends of the rope and pulls it out.
3. We will flatten the plug of the washbasin, then suck the plug with a suction cup, and pull the suction cup up hard, or we can pull the plug out.
