Category: Inground Pool Pump
Inground pool pumps are sized, plumbed, and installed differently from above-ground systems — they typically operate on 230V dedicated circuits, use 2″ plumbing connections, and are selected based on the pool’s total dynamic head rather than just pool volume. Getting the sizing wrong on an inground pump replacement is one of the most expensive pool mistakes: an oversized pump increases backpressure, creates noise, and can damage the filter; an undersized pump can’t turn the water over adequately.
Inground pool pump repairs are also more involved than above-ground work because the pump is typically plumbed with rigid PVC and unions that require specific tools to disassemble without cracking. This section covers inground-specific pump selection, sizing calculation, plumbing union types, in-place repair without removing the pump from plumbing, and the electrical requirements for inground pump installations across the most common inground pool configurations.

Above-ground pool pumps are typically smaller (1/3–1.5 HP), use flexible hose connections instead of rigid PVC unions, and sit above the water level — meaning they fight gravity and lose… Read the Guide →
