Pumps and Hydraulics
Understand flow, head loss, pump speed, priming, and filter matching before you trust any generic hours-per-day rule.

Flow first, folklore second
Pump selection and runtime depend on hydraulic resistance, filter limits, features, and use case. Pool volume alone is not enough.
Identify the pump and its operating modes
You need the exact pump family and controller context before you can interpret speed, noise, or priming behavior.
Think in flow and head loss
Hydraulics are about how hard the system is to move water through, not just how big the pool is.
Use runtime as a result, not a superstition
The correct runtime is the shortest schedule that still preserves sanitation, skimming, and clarity for the pool's real conditions.
Troubleshoot the common pump faults safely
Most owner-level pump troubleshooting is about air, water, and obstruction, not internal motor surgery.

Pump and Hydraulics Boundary
Most pump work is safe while you are working on water, air, and documentation. It stops being owner-safe when the task reaches energized or internal equipment.
- ✓ Inspect water level, baskets, lid seal, valve positions, visible leaks, and normal RPM schedules.
- ✓ Record alarms, compare flow to normal, and clean or service the filter using the correct manual.
- ✓ Shut the pump down if it is running dry, cavitating badly, or overheating.
- ★ Open drives or motor housings, repair high-voltage wiring, replace bonding connections, or disassemble internal motor components.
- ★ Redesign hydraulic layouts, repipe pressure-critical sections, or diagnose motor-controller faults that require enclosure access.
- ★ Interpret electrical drive errors that require energized testing beyond documented owner checks.
- ⚠ The breaker trips repeatedly, wiring smells burned, or the motor housing is overheating dangerously.
- ⚠ The next step would require opening a live enclosure or guessing at bonding and wiring.
- ⚠ The pump is losing prime badly enough to risk dry-running while you continue to experiment.
