Water Hammer: Causes and Preventative Measures
a valve is closed quickly and suddenly stops the flow of liquid. in a pipeline. When this happens, shock waves travel back and forth through the piping system equal to the. speed of sound in that liquid (for water at 70 degrees that is over 4800 ft/sec). These waves travel backward. until encountering

Flow Velocity in Plastic Piping Systems
, however, the shock pressure (sometimes called water hammer) they can generate is. Shock Pressure. This shock pressure, which can be hundreds of pounds per square inch, is often more than enough to cause severe damage to plastic piping systems that are often rated for 150 PSI. This shock pressure can

Plastic Valves Installed in a Metal Piping System
Many times people with a metal piping system are attracted to a plastic valve or strainer because of its low cost compared to a stainless steel or bronze one. And also for all of the benefits plastic offers. Plastic components can, however, be used successfully in metal systems. But you have

23 Questions and Answers about Water Pressure Reducing Valves
. This principles based on. the fact that moving objects, and this includes water,. tend to move in a straight line. They resist changes in. direction. Therefore, in a home where the piping has. many changes in direction, water hammer shock can. be limited by reducing the water pressure. 5 What is the difference
