Problem & Solution No. 1: Water Hammer Effect
Water hammer is the major problem that occurs frequently. Generally, it’s a kind of water pressure or waves caused when liquid and sometimes gas suddenly stops at high-speed. It occurs when a valve gets clogged. You can understand easily by imagining the water flows through the pipes like the car driving on a track. What happens if the front vehicle suddenly breaks die-hardly? Of course, the cars behind that will crush and make a banging sound. And this is what exactly happened when you flush the toilet. The water flows through the pipe suddenly stops and hits the pipe wall, which causes noise.
Solution:
The water hammer effect basically occurs when the air-filled chamber gets clogged or stops. So, you can fix this easily by emptying the air-chamber.
To do that, first, shut off the water supply.
Secondly, flush your toilet and open every faucet in your bathroom.
Then, close the faucets and turn the water supply on. It helps to empty the water and air out from the chamber.
Now, flush your toilet again and listen to whether the banging noise stops or not.
If it doesn’t fix the issue, we recommend you change the shut-off valve and install a new one. You find this in your local hardware or plumbing store.
Problem & Solution No. 2: Bad washer inside the fill valve
The bad washer inside the fill valve is another reason for the foghorn noise. It vibrates when the valve is closing or the toilet is filling, but the tank remains full.
Solution:
Fixing the issue is simple and effortless. You just need to replace the fill valve, which is affordable. It costs you around 10-15 bucks to get a new valve.
The best part is- installing the valve in your plumbing system is a breeze. You don’t require any arcane knowledge or specialty tools.
Here how to do that:
Firstly, turn the water supply off.
Now, drain the tank by flushing the toilet. Keep holding the flush handle until the tank is getting drained completely.
Secondly, both from the valve and the toilet, remove the waterline. Then, unscrew a nut that keeps your old fill valve in place. Afterward, lift out the fill valve.
And finally, install the new fill-valve and do the reverse to complete installation.
