• V-ring protection against abrasive particles
• Internal air circulation helps cool the pump
• Can be moved between puddles after priming without immediately losing prime

Compatible accessory: Automatic Surface Level Switch, sold separately. The switch-only option does not include the Sea Sponge pump.

Read the manufacturer’s operating manual before installing or using the pump. Disconnect the pump from electrical power while positioning it or attaching the discharge hose.

Setup and operation:

1. Identify the lowest point where water naturally collects.
2. Inspect the area and remove large debris that could block or damage the pump.
3. Attach a standard ¾-inch garden hose to the discharge port.
4. Position the discharge port horizontally or vertically according to the required hose route.
5. Route the discharge hose to an appropriate drainage location where the released water will not flow back toward the protected area, damage adjacent property or create another hazard.
6. Prime the pump through the discharge outlet using at least approximately 85 ounces of clean water.
7. Place the pump upright at the lowest point of the area being drained.
8. Connect the pump to a properly grounded, GFCI-protected 110V power source located and managed in accordance with electrical-safety requirements.
9. Start the pump and confirm that water is flowing through the discharge hose.
10. Monitor the hose, discharge location, pump stability and surrounding water level during operation.
11. If using the optional Surface Level Switch, install and test it according to its separate instructions before relying on automatic operation.

Important considerations:

• The pump must be primed before initial operation.
• Flow rate decreases as discharge-hose length, restrictions and vertical lift increase.
• Do not exceed the pump’s maximum 39-foot head.
• Keep plugs, extension connections and electrical equipment appropriately protected from water.
• Use only properly rated outdoor electrical equipment when operating outside.
• Follow the manual’s requirements concerning acceptable liquids and debris.
• If used with salt water, flush the pump thoroughly with fresh water after operation and wipe down exposed components.

After use, disconnect electrical power before moving, inspecting or cleaning the pump.

How much water can the Sea Sponge pump move?

The maximum rated capacity is 45 gallons per minute. Actual flow may range from approximately 13.2–45 GPM depending on discharge-hose length, vertical lift and other site conditions.

How low can it drain standing water?

The pump can reduce water to approximately 0.04 inches on a suitable flat surface.

Does the pump need to be primed?

Yes. Prime it through the discharge outlet with at least approximately 85 ounces of water before initial operation.

What type of hose is required?

The discharge accepts a standard ¾-inch garden hose. The port can be positioned horizontally or vertically.

What is the maximum vertical lift?

The pump has a maximum rated head of 39 feet. Flow decreases as the vertical lift and discharge-hose resistance increase.

What power source does it require?

Sea Sponge operates on 110V AC and draws approximately 6.1 amps. It should be connected to an appropriately grounded and GFCI-protected power source.

Can it run automatically?

Yes, when used with the compatible Automatic Surface Level Switch. The switch can activate the pump when water is detected and turn it off as the water level falls. The switch is sold separately and does not include the pump.

Can the pump run when very little water remains?

The design permits prolonged low-level pumping and internal air circulation helps cool the motor. Operation should still follow the manufacturer’s manual and the pump should be monitored appropriately.

Can I move the pump between puddles?

Yes. Its internal check valve helps retain the prime, allowing the pump to be moved between shallow collection areas after it has started.

Can it be used outdoors?

Yes, provided an appropriate power source and proper electrical protection are available. Electrical connections must be protected from water and rated for the environment.

Can it pump salt water?

Garrison states that the pump may be used for salt water, but it must be thoroughly flushed with fresh water and wiped down afterward because salt can corrode and degrade components.

Is the maximum 45 GPM guaranteed with any garden hose?

No. Hose length, bends, restrictions and vertical lift affect the actual flow rate. Use the shortest practical discharge route and avoid unnecessary restrictions.

Where should the pump be positioned?

Place it at the lowest point where water naturally collects. Route the discharge to a safe location outside the protected area.
