Why do Water pipes  make a  loud noise? this can be described as a clunk or a vibration or even the sound of a dining room chair being dragged across the floor. This is happening because you have 40-60 psi of water depending on where you live entering your house. When a faucet is closed or a fill valve, you are stopping that 50 psi in your water pipes in an instant. This can cause water pipes to make a loud noise. Your water pipes need a water hammer arrestor to cushion the pressure.

Water pipes making a ticking noise

This ticking noise is caused by water pipes being installed to tightly when they were installed. I say to tightly meaning that when the holes were drilled through the floors and walls to allow the water pipes to be ran they were drilled to small and the water pipe is very tight in the opening. When the water is opened to a faucet the water pipes will naturally expand and contract. The ticking noise your hearing is the water pipe trying to move.

The only way to fix this is to open up the walls and re-do the waterlines unfortunately.
