A solution to correct water hammer in plumbing systems involves re-fastening loose pipes and installing air chambers or shock absorbers. Water hammer is a phenomenon that occurs when there is a sudden change in water flow, typically due to quick-closing valves, which creates a shock wave that can cause pipes to rattle or bang.

By re-fastening loose pipes, the physical movement and vibration caused during water hammer can be minimized, preventing additional noise and potential damage. The installation of air chambers or shock absorbers provides a cushion for the shock waves, effectively absorbing the energy created by the abrupt flow changes. These components help to stabilize the pressure in the system and reduce or eliminate the banging noise associated with water hammer.

While the other options might seem relevant at first glance, they do not directly address the root cause of water hammer as effectively. For example, installing larger pipes may alter flow rates but does not specifically mitigate the effects of pressure changes. Replacing old pipes might improve the overall plumbing system but would not necessarily solve water hammer unless the new system includes features to absorb shocks. Lowering the water pressure can reduce the severity of water hammer but does not address the immediate need for cushioning the shock waves caused by sudden flow changes.
