A faulty toilet fill valve that doesn’t close completely or a quick-closing fill valve are both possible causes of water hammer that occurs after you flush a toilet.
Can water hammer burst pipes?

Where are water hammer arrestors installed?
The best places are either close to the pump, isolation or check valve that is originating the hammer, or at more distant points where the pipe changes direction, for example at the top of a pump riser.
What happens if you don’t fix water hammer?
Water hammer can damage and wear away at pipe joints and valves over time. Worn out pipes may burst, start leaking, or detach from their connections. If your shockwave happens because of high water pressure, it can also pose a physical risk.
