Bilge Alarms & Switches

Bilge Pump Switches, Bilge Alarms and Detectors, Bilge Counters

Water that does not run off the side of the deck (from rough seas, rain, leaks etc...) collects in the bilge of your boat. Using a bilge pump system, the bilge water must be pumped out of the hull to prevent sinking.
Get reliable bilge alarms to keep you updated on bilge levels, even when docked! Receive alerts through email and text with our new 20240-CA High Water Alarm. We also carry a large selection of wireless, sirens, large commercial bilge alarm bells and the necessary pumps and switches to set-up and operate your entire warning system.
