Noisy pipe when toilet flushed

Question

Why do my pipes make noise when the toilet is flushed? Every time someone flushes the toilet, there’s a banging or rattling noise from the pipes. What is likely to be the problem and how urgent is it?

This is called water hammer. Replace the ballvalve on the toilet as that is a normally the problem. I'm guessing when you flush the toilet and the cistern refills with water the noise starts to happen as the tank is almost full of water and the ballvalve is beginning to shut off. Water hammer can also be caused by a faulty stopcock or a faulty tap valve. But my money is on the toilets ballvalve.

It's called water hammer. If you have any valve under your cistern on the toilet turn it down a bit  if not then turn down the the main stop tap for the time being but you could do with a new ball valve or washer inside the old one

We understand you're experiencing some noise when flushing the toilet. It sounds like there might be an issue with the water flow mechanism. A common cause for such sounds is a malfunctioning inlet valve. Addressing this promptly can help restore quiet operation to your bathroom. We recommend having a professional inspect the internal components of the toilet.
