Plumbing & Equipment

\n Every pipe, fitting, and piece of equipment creates head loss — back-pressure that reduces\n your actual GPM below the pump curve's rated output. Describe your system to find the real operating point.\n

\n Main Plumbing Size\n \n

1.5\" vs 2\" makes a big GPM difference at higher flows.

\n Total Pipe Run (feet, both supply & return)\n \n

Pump to equipment pad and back. Typical residential: 60–120 ft.

\n Number of 90° Elbows\n \n

Each elbow ≈ 5 ft equivalent pipe. Typical: 4–8.

\n Static Head — elevation difference (feet)\n \n

Uphill = positive. Most in-ground pools: 0–3 ft.

Power Draw vs RPM — Full Curve

Solid dot = current operating point. Power follows the cube law — halving RPM cuts power to ~1/8th.

\n\n \n

\n Single speed pumps run at one fixed speed — typically 3,450 RPM (full speed). They cannot be slowed down to save energy. \n Most residential pools ran these for decades; variable speed pumps typically pay back the upgrade cost in 1–3 years.\n
