Works well
Admittedly I left my primary bilge off overnight and a valve was leaking enough to trigger the high water alarm. Around 6am in the morning someone was walking by and heard the bilge pump cycling and the alarm going off. They called the marina, who then called me and I rushed down to turn it off. Not too loud to piss people off but just enough to cause concern. It worked well and I highly recommend it for your secondary upper pump.

Works as expected. Would have liked to have been able to mount it on the side of the bilge due to space without creating a special bracket.

Easy Install and Works!
Super easy to install and functional. I sold a boat and they now recommend a high water alarm be installed. This did the trick!
