Anyone know how to fix this issue?

When I closed it, there is no noise and vibration. If I open it, the noise and vibration are there, unless I turn smaller.

I opened. And also let the water flows out from there. Still the same.

But I have yet to try to off the stop and open other faucet or shower drain to let all water out?

How to replace? Can't take it out.

Yes, it is concealed and I have no way to open the whole without ketuk the wall first.

What is the effective way to flush out the air inside?

The vibration is until another toilet's pipe and the sound is very loud like wuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

From AI

To get air out of water pipes, start by shutting off the main water supply valve. Then, open all faucets and flush toilets to drain the system. Finally, turn the main water supply back on slowly and open each faucet to let the air escape until the water flows steadily.
Here's a more detailed breakdown:

1. Turn off the main water supply:
Locate the main water valve, usually near the water meter, and turn it off to stop the flow of water.

2. Open all faucets and flush toilets:
This allows the water and trapped air to drain from the pipes. Start with the highest point in your house (e.g., the top floor) and work your way down.

3. Turn the main water supply back on:
Slowly turn the main valve back on to allow water to flow back into the system.

4. Release the air:
Open each faucet halfway, starting from the highest point and working your way down, to let the air escape. You may hear sputtering or air hissing at first.

5. Close the faucets:
Once the water flows steadily from each faucet without sputtering, close them one by one, starting from the lowest level and working your way up.

If the problem persists, you may need to contact a professional plumber to investigate further.

the one is my picture?

thanks for this video

let me find out on how to "kepik" the thing to take off the whole

it looks like no kaki tangan to kepik because the tiles sangkut

cool

thanks for this recommendation. Let me go 5 jingdian shop

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.

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