Plastic water tanks can flex considerably, so they should have a reinforcing plate (metal) to stop them moving.

Can a bad shower valve cause water hammer?

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.

To fix the issue, homeowners need to drain their plumbing system: Shut off the main water valve, open the highest faucet in your home, and drain water from the lowest faucet (usually in the basement or first floor).
