Typically, the piping should be sized large enough so that frictional pressure drops within the piping system make up less than 10% of the operating pressure of the system. For example, a system operating at 100 psi should have less than 10 psi of frictional pressure losses in the piping system. PreRead more
Typically, the piping should be sized large enough so that frictional pressure drops within the piping system make up less than 10% of the operating pressure of the system. For example, a system operating at 100 psi should have less than 10 psi of frictional pressure losses in the piping system. Pressure losses in a piping system can be readily determined using the “equivalent length” method that is found in most piping handbooks. Since most piping systems are not complex, we have developed over the years a simple rule of thumb for sizing the piping. We generally recommend 5-10 feet per second in the supply pipe and 3-5 FPS in the return pipe.

A properly designed system will have ports at the high points for venting air. While the system is running, vent the high points in the process discharge piping to remove air from the pipe.

A properly designed system will have ports at the high points for venting air. While the system is running, vent the high points in the process discharge piping to remove air from the pipe. Most problems with the initial start-up are associated with filling the system and releasing air out of the process piping. Blocked air can resist or prevent proper water flow. We do NOT recommend automatic air release valves. They are too prone to leaks.
