Comments about Rule Industries High Water Bilge Alarm:
I have a 90 year old wood commercial fishing boat so I am always worried about worst case scenarios. Coast Guard regs require that I have a high water alarm so I bought and installed this. Recently, rough conditions opened up a seam between two planks and my automatic bilge pump was handling it, so I wasn't aware of the major leak in my hull. The float switch failed, therefore, the automatic bilge pump stopped. My bilge filled up, the alarm went off and my slip neighbor heard it. This alarm saved my boat from sinking!
I replaced the float switch, filled the seam and thanked this alarm for saving my boat. Easy install and worth the time and money!
Remember, it is the cheapest part that fails and sinks boats. This would have been the 8 month old $40 float switch. Always have back ups!
