Thanks! This stuff I understand from having a saltwater reef tank for years and maximizing flow rates at head pressure!You want to keep the water velocity below 6 ft/sec on the suction and below 8 ft/sec on the pressure side of the pump.[7]

Make sure that the pipe is sized correctly.
Spa jet pumps need big pipe.
Sweep 90s are nice, but not critical if the pipe is sized correctly.
What does it mean "No plumbing runs"?Sheer Descent - 4' (*includes flow control valve - no plumbing runs)
It’s just the way the quote is itemized. That’s the line item in their system for the sheer descent that they add and then the plumbing is covered under the overall plumbing section.What does it mean "No plumbing runs"?
