When water flows into the tank, the valve float rocks up and down, constantly closing and opening the valve. This creates a “wave system” that echoes along the pipes, causing the hammering sound. Plastic water tanks can flex considerably, so they should have a reinforcing plate (metal) to stop them moving.

Water hammer gets worse when the pressure is too high. Higher pressure causes, or allows, the water to flow faster through the pipes. WHen you shut a valve off, that higher velocity translates into higher inertia, which is like the difference between walking into a wall versus running into one.

Why are my shower pipes knocking?

A: The knocking sounds are what’s known as water hammer, caused when water flowing in pipes suddenly shuts off and vibrates with enough force to cause the pipes to knock against wood framing.
