What s going on with the sizzling toilet tank, will the leak seep into the ceiling of the bedroom do

The sound is the sound when it is through the valve, as long as the waterproof layer of the bathroom is not damaged during the decoration, it will not leak.

Only one ring is the water tank is entering the water, and if it keeps ringing, it may be that the float valve is broken and needs to be replaced!

If it has been sizzling: in the toilet tank, there is a water supply pipe, the water supply pipe is controlled by the float, the float is lifted to the highest position, it should be able to completely close the water supply pipe, but the rubber ring at the water supply pipe is not well sealed, there will be a small amount of water still entering the water tank, so as to make a sizzling sound, after the water enters the water tank, the excess water will overflow into the toilet, you will find that there has been a sizzling sound because of the time, there will be very little water flowing down the inner wall of the toilet, therefore, it will not seep into the roof downstairs.

If you just make a sound when you replenish the water, there will be no sound after the water, so you don't need to care about it, you can use it normally.
