Where should Mechanical Pressure Absorbers be located?

Mechanical Pressure Absorbers are devices used to mitigate the effects of water hammer and pressure surges in plumbing systems. Their primary function is to absorb sudden changes in water pressure, which can occur when valves are abruptly closed or when there is a sudden change in water flow.

Placing Mechanical Pressure Absorbers at the end of long runs of water pipe is ideal because it provides the most effective means of absorbing pressure fluctuations that can be amplified along the length of the pipe. Long runs of piping are particularly susceptible to pressure surges due to their length, which makes the energy from a hammer shock wave more pronounced. By installing absorbers at the terminal ends of these runs, they can effectively dissipate the energy before it can cause damage or disturbances in the system.

It is important to note that while the main supply line may benefit from pressure regulation, the specific function of Mechanical Pressure Absorbers is better served at locations prone to pressure changes, such as long runs. Placement next to water heaters can be beneficial for temperature stabilization but is not the primary intent of these absorbers. Installing them only in commercial buildings neglects their potential utility in residential settings, where water hammer can also be a significant issue.
