AQUASTRONG Pool Cover Pump 3/4 HP — 3,487 GPH Automatic On/Off, Bottom Suction to 1/4"

The AQUASTRONG pool cover pump is a 3/4 HP automatic submersible unit that moves up to 3,487 GPH and evacuates water down to a 1/4-inch depth for fast, hands-free cover and surface drainage.

Built for seasonal pools, hot tubs, window wells and basements, this compact submersible pump combines a high-flow motor with a two-stage smart sensor so it starts and stops automatically. A selection of hose and snap-coupling adapters lets you connect standard garden hoses or larger discharge fittings, while anti-freeze and thermal protections guard the unit from common hazards. The pump is rated for a lift up to 29.53 feet and includes accessories for immediate use.

How does the automatic on/off sensor work?

The pump uses two sensor triggers to manage startup and shutdown without manual intervention. The primary sensor activates around 2.28 inches of water; if it misses the level, a secondary trigger engages at 2.87 inches. After water recedes, the pump continues running for 20 seconds and then will stop once levels drop to approximately 0.91 inches.

• Primary activation at 2.28 inches for quick response
• Secondary backup trigger at 2.87 inches for reliability
• 20-second run-down after levels fall to avoid false stops
• Operates only when submerged — plug in after positioning in water

What kind of flow and suction performance can I expect?

This model delivers a high-capacity 3,487 gallons per hour (GPH) and is engineered with bottom suction to remove water close to the surface. It can lift water vertically up to 29.53 feet and will clear water down to roughly 1/4 inch, making it suitable for flat cover drainage and shallow sumps.

• Maximum flow: 3,487 GPH for fast removal
• Maximum vertical lift: 29.53 feet for long discharge runs
• Bottom suction reaches to about 1/4 inch for near-dry results
• Good for both above-ground and in-ground applications

Which adapters and fittings are included, and how do I connect them?

The pump ships with multiple adapters to match common hose and pipe sizes so you can use it right away. Included is a 3/4" garden hose adapter with a built-in check valve and a 1-1/2" elbow adapter; snap coupling adapters are provided in several sizes to fit standard submersible pump connections.

• 3/4" garden hose adapter with check valve for quick garden-hose hookup
• 1-1/2" elbow adapter for larger discharge lines and reduced backflow
• Snap coupling adapters available in Φ1", 1" NPT or Φ1-1/4" options
• Quick assembly — no specialty tools required for most connections

What protections prevent damage from freezing, debris, or overheating?

The pump incorporates an automatic anti-freeze detection that will shut the unit off if ice formation is sensed, helping protect internal components. It also includes a self-resetting thermal overload protector that cuts power during overheating and restarts the pump after temperatures return to safe levels.

• Automatic anti-freeze detection to avoid damage from ice
• Self-resetting thermal overload protector for safe recovery
• Impeller lock protection reduces damage from debris or jams
• Durable housing built for seasonal outdoor environments
