Water Hammer Potential

The calculated water hammer potential shown below is for Schedule 80 pipe, flowing water or fluids with a water like viscosity at 60F. Contact Hayward for information on other fluids or temperatures. Hayward recommends a maximum line fluid velocity of 8 feet per second. (5 feet per second for lines with solenoid valves installed). Data used to generate this calculation is based on reference date on file that we believe to be correct. It is the end users responsibility to verify the validity of the calculation for his/her application.
