Water Hammer in Pipe-Line Systems J. Záruba
Publisher: Elsevier Science

The pressure of the fluid Check Valves are used to check the pressure surges associated with hydraulic forces, for example, water hammer; Check Valves are used to prevent the flooding that can take place if flow reversed. I have the usual CPVC pipes for the hot water heater. Check valves or non-return valves are self actuated valves and designed to prevent the reversal of flow in a piping system. There is an API 1149 on leak detection system. Thanks to TRU Engineers and Town of Oliver staff for pictures and explanation. Pipeline system in some type of anti-volatility set up measures to reduce water hammer. When I cycle through the sprinkler zones, I can see the water lines going into the water heater physically shake. In other words we can say This flowing material may be gas,water ,air ,oil or steam in pipeline. Water hammer commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe. The first was a simple basic water hammer program for a pipe with a reservoir upstream and a valve at the downstream end which could close instantly. The sprinkler controller is right next to the water heater. Seven increasingly complex computer models were developed to represent the pipeline. This can be inflated with a pressure relief valve or hose completion, inflatable hose can reduce the length of the pipeline. I think one of the methods works on method of characteristics (MOC) used in water hammer analysis. I don't know if this is new or not, but the pipe has to go from the main all the way around the house to the other side, probably 80-100 feet to the sprinkler valves. Then it comes out to the sprinkler system.
