## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well
*by T***Y on March 28, 2014*

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.

### ⭐⭐⭐⭐⭐ Boat

### ⭐⭐⭐⭐⭐ Perfect replacement
