Buying Guide
What to consider when choosing a submersible pool sump pump:
- Flow rate vs. lift: Higher GPH is faster for large volumes; ensure the lift height matches your drainage area.
- Debris handling: Look for low-suction intakes and filters to prevent clogging in pool debris scenarios.
- Cord length and portability: Longer cords offer greater reach; consider weight for easy transport.
- Construction material: Thermoplastic housings resist corrosion but may be lighter; consider durability for outdoor use.
- Discharge fittings: Ensure compatibility with your hoses and adapters (NPT and GHT options).
- Dry-run protection: Some models include thermal overload protection or sensors to avoid motor damage when water is low.
- Maintenance: Removable bottoms or clean-out features simplify debris removal and extend pump life.
- Best use scenario: For large-volume pool drainage, prioritize high GPH and solid handling; for cover drainage or small areas, a lower capacity pump with robust weatherproofing may suffice.
