Hugh is correct, any quick closing valve needs a water hammer arrestor. The linear movement of the water comes to a complete halt and hammers the pipe. We install them for washers, diswashers and even ice makers. In lieu of an arrestor an air chaer could be installed, a pice of pipe tee''d in and capped off just past the valve. _____

Water Hammer Information

The third factor that influences water hammer is the velocity of the water. The faster the water is traveling in the pipe, the greater the water hammer. It is this last factor which is easiest for us to correct in a sprinkler system, so most of the suggested solutions for water hammer will be aimed at reducing the water …

Preventing Water Hammer from Damaging Pumps and Pipes

Water hammer is a shock wave passing down the pipe as a result of a sudden flowrate change. The most common cause is a valve closing too quickly, or a pump tripping or starting up suddenly. This causes a shock wave which starts at the valve or pump and passes along the pipe, changing the fluid velocity as it goes.

Calculating Horsepower Requirements and Sizing Irrigation

In sizing irrigation water supply pipelines, two fac-tors are important: friction lossesand water hammer; both are influenced by the relationship between flow rate (or velocity) and pipe size. Water Hammer When moving water is subjected to a sudden change in flow, shock waves are produced. This is referred to as water hammer or surge pressure
