There is no reason why the toilet leaks. After the floor tiles were knocked out, the cement floor was wet.

After knocking on the ground, close the main indoor tap water valve, and don't rush to repair it, so that the underground water can penetrate completely. After a few days, there will be no water stains on the ground. You can open the tap water valve, observe the direction of the ground being struck, and then strike the ground along the direction of the water, so that you can accurately find the location of the water leakage, and then carry out secondary suppression after repair.

Press the tap water pipe 8- 10 kg. If the pressure does not drop, it means that the groundwater leaks after bathing. If the pressure drops quickly, it can be proved that the water pipe is leaking.
