Review AQUA ALARM 2004 Bilge Pump

The AquaAlert 20042 Bilge Pump is a reliable and efficient solution for keeping the bilge of your boat free from excess water. This submersible pump is designed with a powerful 1/3 horsepower TEFC ( Totally Enclosed Fan Cooled) motor that delivers a flow rate of approximately 1,400 gallons per hour (GPH), making it capable of handling even large amounts of water quickly and effectively. The motor is protected by a thermal overload switch, which automatically shuts off the pump in case of overheating, ensuring the longevity of the motor.

The pump housing is constructed of corrosion-resistant materials, including a 316 stainless steel shaft and a glass-filled polypropylene body. This makes the pump well-suited for use in marine environments where exposure to saltwater and other corrosive elements is common. The pump also features a heavy-duty impeller with 13 stainless steel blades, which provides excellent suction power and resistance to wear and tear.

The AquaAlert 20042 Bilge Pump comes with a 12-foot power cord and a 10-foot discharge hose, allowing for flexible installation options. The pump also includes a float switch, which automatically turns the pump on when the bilge water level reaches a certain point and turns it off when the water level drops below that point. This provides hands-free operation and helps prevent the pump from running unnecessarily, saving energy and extending the life of the pump.

The pump is UL (Underwriters Laboratories) listed, ensuring that it meets the highest standards of safety and quality. It is also CE (Conformit Europ ene) certified, making it suitable for use in Europe. With its powerful motor, durable construction, and automatic float switch, the AquaAlert 20042 Bilge Pump is an essential piece of equipment for any boat owner, providing peace of mind and protection against water damage.

The AquaSafe AQUA ALARM 20042 is a combined bilge pump and alarm system designed for small boats and vessels. Here are some pros and cons of buying this particular model:

1. Combination of a bilge pump and alarm system in one device, reducing the need for separate components.

2. Automatically turns on the pump when the water level is detected, ensuring continuous operation during heavy flooding.

3. Compact and lightweight design, making it easy to install and transport.

4. Floats on water and has a built-in handle for easy removal and manual operation.

5. The alarm system features a loud buzzer and a flashing light, alerting the user to potential flooding.

6. The pump has a flow rate of 2,200 GPH, making it suitable for small to medium-sized boats.

1. Some users have reported that the alarm system may be too sensitive, triggering false alarms.

2. The pump's impeller may clog easily, requiring frequent cleaning or replacement.

3. The cord length may not be long enough for some boat configurations, requiring additional wiring or extension cords.

4. The battery life of the alarm system may be relatively short, requiring frequent replacement or recharging.

In conclusion, the AquaSafe AQUA ALARM 20042 offers a convenient and effective solution for small boat owners who want a combined bilge pump and alarm system. While it has some limitations, such as potential false alarms and short battery life, the benefits of having both functions in one device and the pump's robust performance outweigh these cons. Overall, this model is a recommended option for those looking for a reliable and easy-to-install solution to monitor their boat's bilge.
