Under normal circumstances, because of the presence of water pressure, the water will not flow back into the water tank, let alone into the water pipe. If the water tank inlet pipe is lower than the water level of the water tank, sometimes there is a local vacuum in the water pipe after the water is stopped, and the negative pressure generated will pump the water in the toilet tank into the water pipe, and it is best to install a check valve on the water pipe on the water tank, so that there will be no problem of water backflow in the water tank. Hope this helps. >>>More
