Rated 4.5 out of 5 by 10 reviewers.
Rated 4.0 out of 5.0 by Good buy so far Bought this to replace the junk pump in a rental property. It moved alot of water in a short amount of time. The water in the crawl space was about 3 feet deep and this pumped it out in about 20 minutes. Did not drill the air hole pipe as was not in the instructions but will go back and do this later. I am pleased with this pump so far but time will tell for sure. Would definately buy this one again if I need to. March 22, 2015
Rated 5.0 out of 5.0 by great pump Very easy to install Just wish it came with a fitting for the hose January 6, 2015
Rated 5.0 out of 5.0 by Works like a horse Easy install, i tested it and it pumps out water with so much power i can only sit back and not worry even if it rains cats and dog! October 28, 2014
Rated 5.0 out of 5.0 by Installed pump, on a test the pump lifted 8 gallons of water straight up 9 feet up in 7 seconds. The pump was easy to install. Instructions were adequate. Installation looks good. December 10, 2014
Rated 5.0 out of 5.0 by Glad I bought it I am so glad I read the reviews on this pump because it persuaded me to purchase it and I am glad I did. Started right up and has run perfectly without issue. The only question I had was that the User's documentation said that the pump had a built in air valve to prevent airlock and does not say to drill an air lock release hole in the discharge pipe. However, the quick instructions definately point out an air lock release hole in the discharge pipe. I called the company and they said to drill the hole in the discharge pipe to give the pump every opportunity to not get air locked. Compared to other pumps of lesser quality and not as reliable, this one is well priced. June 11, 2014
Rated 3.0 out of 5.0 by Basemaent Watchdog 1/2 HP Submersible Sump Pump I bought the Basement Watchdog back up system for the sump system I have, which is in a confined space in a narrow sump well. After considering how to install it for some time, I decided that the best way was to replace the olr pump ( motor sits atop a pipe pedestal, with long float switch system) to a submersible pump motor. They sell the complete system at the Basement Watchdog site, but not at my HomeDepot. It would be an expensive, and daunting system to purchase that way. But in for a penny, in for a pound. The base of the main submersible pump being reviewed is plastic and a little brittle. A chunk broke off leaving a hole that debris could get into and possibly clog the works. I had to improvise a screen from wire cloth and affix it to the pump. Then I made several trips back to HD for all the little pieces parts I needed to build the pipe system. Then there was the nerve wracking gluing of the system together, and installing in place in the confined space I have. Since I installed it in January, my hose bibs are all shut off, and to test the system would require carrying buckets of water down a ladder into the space where the system is, so I won't be sure it works until spring, or if we take on water. The motors come on when the floats are moved, so I think it will work properly. I think the act of installing the system will act like a totem - scaring water away from my foundations forever. ;>) Some folks might need professional help. I've been told that many times myself.

Rated 5.0 out of 5.0 by Rugged and Durable Do yourself a favor, pay a little more money than buying the cheap pumps, and get this one. It is slightly more money, but just lifting it I can tell it is better built than the cheap piece of junk the builder put in my house originally. Of course time will tell how well it holds up.

Rated 5.0 out of 5.0 by Easy installation I bought this to replace a sump pump that went bad. I installed it along with watch dog's battery back up. The sump pump is really powerful, when I tested it, I could not keep up with how quickly it discharged the water I was pouring into the basin. Hopefully it's long term quality matches up with it's power. January 31, 2012
