Score: 75/100
SEAFLO Marine Water Pump
Score: 85/100Rankings
The Seaflo 55-Series 5.5 GPM marine water pump is a heavy-duty, self-priming diaphragm pump designed for high-volume applications in marine, RV, and off-grid settings. It delivers 60 PSI of pressure with a flow rate of 5.5 GPM, supporting up to five simultaneous outlets without requiring an accumulator tank, though one is available for reduced cycling. While it offers excellent performance and durability, the high amperage draw requires careful electrical planning.
The Little Giant APCP-1700 is a 1/3 HP automatic submersible pump designed to remove standing water from pool covers, boat covers, and flat roofs. It features a mechanical float switch that activates at 2 inches of water and deactivates at 1.5 inches, offering a high flow rate of up to 1745 GPH at low head pressure. While effective for its intended purpose, it is not suitable for continuous duty or dirty water applications.

Professional reviewers and editors highlight the Little Giant APCP-1700 as an industry-leading solution for preventing pool cover damage due to its high flow rate and automatic operation. They praise its energy-efficient motor, quick activation, and robust construction, noting it is ideal for all types of pool covers. However, in-depth expert tests are scarce, with descriptions focusing primarily on specifications rather than hands-on verdicts.
Consumer feedback is sparse but generally positive regarding ease of use and effectiveness. Users commonly praise the pump's portability and ability to remove water quickly. The most recurring complaint is the tendency for the pump to air lock, which stops operation and requires manual fixes, such as using two hoses to prevent air intake.
Professional reviewers and editors highlight the pump's heavy-duty build quality and consistent performance, noting its ability to support multiple fixtures without pressure loss. Experts praise its quiet operation and built-in thermal protection, positioning it as an economical yet reliable workhorse for boats and RVs. The inclusion of an accumulator tank is recommended for surge prevention and reduced cycling, enhancing overall system stability.
Everyday users and consumers generally praise the pump for its reliability in marine and RV setups, with high ratings on retailer sites indicating strong satisfaction. Common praise focuses on the strong pressure output and the ability to support multiple outlets simultaneously. Recurring complaints are minimal but include occasional priming delays when the system is air-locked, requiring patience during startup.
