Works as advertised
by Reid from Winter Haven, Florida on June 19, 2017
This pump was bought to replace original that was in bilge for over 12 years. Works as expected, time will tell. Float switch on old pump started sticking but old pump still worked. Hope to get similar life out of new one. Pumps water out of bilge fast

Perfect match for my 2013 Boston Whaler
by John from Dekalb, Illinois on February 23, 2016
This pump is a perfect match for the one in my 2013 Boston Whaler. I like the manual test lever for the float switch. The float switch in my original pump failed after 2.5 years but the pump still worked on manual. Now I know how to test it.

Love This Pump!
by Patrick from Beaufort, South Carolina on August 16, 2014
It was easy to install and works like a charm. I purchased it to replace a Rule-Mate that had quit working on automatic. Presumably, the "high Tech" switch failed but how and why and, most importantly, there is no way to remedy the problem. I was delighted and relieved to find the Atwood has a float switch when I received it. If it fails on automatic, I'm pretty sure it will be a simple thing to clear any debris that might be fouling the switch so it will work again. Of course, if I keep the bilge clean, there should be no reason for the float switch to fail.

GOOD for the price
by ROY from MARMET, West Virginia on September 14, 2013
This is the second on of this model I have had , the first was a great pump. I gave it a 4 out of 5 only because it had trouble handling bleach water we cleaned the boat deck with . This caused the plastic to have problems crack open then water killed it .....
