Maximum Flowrate!

One of the key performance advantages of a PVC piping system is its glass-like internal finish

One of the key performance advantages of a PVC piping system is its glass-like internal finish. This hydraulically smooth surface means that PVC systems can cut friction losses and increase flows for a given pipe size. These hydraulic benefits apply to both pressure and gravity flow applications, and have been proven through extensive research and field testing. Fluid will flow over a smooth surface more easily than it will over a rough or uneven surface. Since the inside finish of various pipe materials have varying degrees of roughness, flow characteristics of each pipe material differ significantly

A common mistake many homeowners and inexperienced contractors make is using too small of a pipe for the flow rate of their pump.  Always use the same size pipe, or even larger as the discharge port on the pumps.  Example:  A pump with a 1 1/2"  discharge would need a minimum 1 1/2" pipe or even 2".
