The chamber loses air as water come and go so it becomes less shock absorbent over time causing that unwanted hammering noise.

Either of these solutions will reduce vibrations and water hammer. Ensure that the silicone is distributed evenly around the pipe when a wall stud is penetrated. Therefore the louder or longer the hammering will go on for. It is a short segment of vertical pipe installed near the valves. Next turn all faucets you could find around the house on.

By reducing the water pressure you can eliminate the issue. If there is a wooden beam nearby you can strap the supply lines down. Take note of anywhere you might be able to add pipe straps or insulation to stabilize the supply lines. One of the simplest methods for fixing hydraulic shock or water hammer is installing an air chamber. Watch the video for a simple solution that should make it stop.

This creates an effect of air filled pipe that acts as a tampon for the next time when water changes direction suddenly. Let the low faucet drain until nothing comes out.
