I have a new toilet with a Fluidmaster valve. As the tank fills and the water is shut off by the valve, there is a thunk noise that can be heard throughout the house. The noise itself does not seem to transmit through the water inlet pipe when I place my hand on it. Is this noise harmful and how do I get rid of it?

Thank you,

Ron

Anytime a quick closing valve causes hydraulic shock waves (water hammering)

There is a very good possibility of rupturing a pipe

More info if your interested in the Neddy stuff in plumbing

Water hammer is a pressure surge or shock wave caused by the kinetic energy of a fluid in motion when it is forced to stop For example, if a valve is closed suddenly at an end of a pipeline system a water hammer wave propagates in the pipe. Moving water in a pipe has kinetic energy proportional to the mass of the water in a given volume times the square of the velocity of the water.

\mathrm{kinetic\ energy} \propto \mathrm{volume} \times \mathrm{velocity}^2

If the pipe is suddenly closed at the outlet (downstream), the mass of water before the closure is still moving forward with some velocity, building up a high pressure and shock waves.

In plumbing this is experienced as a loud bang resembling a hammering noise. Water hammer can cause pipelines to break or even explode if the pressure is high enough
