TS, when it started to make noise? All these while ka? Or recently got water cut then after that start making noise.

can't remember well but it happened before but when i open fauclet to use, the noise will go off but it won't go off recently. So I need to on and off the switch whenever i wanna use the toilet.

when it vibrates, i can fee from the meter reading punya pipe there.

If I flush the toilets, the noise goes off as it needs to refill the tanks. After the tanks is full, then the noise datang balik.

Looks like this valve rubber seal sweel already didn't fully open to the max, may be need to change new rubber stopper seal

I am trying this but i need to be able to open it first. Learning.
