Frequently Asked Questions

What is a high water bilge alarm and why do I need one?

A high water bilge alarm detects dangerously high levels of water in your boat's bilge compartments. It provides an audible and visual alert, giving you early warning of leaks or pump failures before significant damage occurs. It's crucial for marine safety, especially on boats with enclosed compartments or when the vessel is unattended.

How does the Seaflo WAS12002 alarm work?

The Seaflo WAS12002 uses a non-mercury float switch mounted in the bilge. When water rises to a specified level (45-55mm), the float activates, triggering both a loud 95 dB alarm and a visual flashing indicator to alert you to the problem.

Is this bilge alarm easy to install?

Yes, the Seaflo WAS12002 is designed for straightforward installation in most 12V marine electrical systems. The alarm head unit is surface-mountable, and the float switch can be easily positioned in your bilge. Basic wiring knowledge is typically sufficient for installation.

Can this alarm be used with my existing bilge pump?

The Seaflo WAS12002 is primarily a high-water alarm system and can be used in conjunction with your existing bilge pump setup. It is rated to handle pumps up to 20A at 12V, or 10A at 24V. Its purpose is to alert you when your primary bilge pump might be overwhelmed or has failed, providing an essential backup safety layer.

Note: Please verify your vessel's voltage and current requirements before purchasing.
