CUSTOMER REVIEWS

Rated 4.6 out of 5 by 50 reviewers.
Rated 5 out of 5 by Great sump pump! Our old sump pump (20+ years) failed when we got a lot of rain from the remnants of Hurricane Isaac, partially flooding our basement. I did a lot of research trying to find a quality combination primary and battery backup sump pump at a decent price, and I definitely found it! Home Depot had a very competitive price and got it to me very quickly. This was my first sump pump install, so it took me some time, but it was very easy. The only drawback was that I had to buy the battery and acid separately and pour the acid into the battery myself - a little nerve-wracking, but no problems. I thoroughly tested the system, and both the primary and battery backup pumps work perfectly. December 3, 2012
Rated 5 out of 5 by Well thought out and packaged product To start, my pump went out in the middle of the night so I was up all night bailing water out of my sump hole. had to redirect the back up pump to pump using a garden hose as it could no longer push the water up 10ft through a 1-1/2" pipe. So thank goodness Home Depot opens at 6:00AM. I was on their doorstep first thing. Purchased this pump after spending 3hrs researching the web, for the package of the main pump, back up pump, directional valves and controller. All in a small package and no loose float (mine would get pinched against the wall of the hole cause the pump would walk due to vibration from running). Very simple installation, anyone could do this. Bottom line i was still into work by 8:30AM. Also very quite, i know no longer hear the pump running from the bedroom. Awesome product and great value when you add up everything you get, try and buy it all seperate at a lower price and same quality. February 1, 2013
Rated 5 out of 5 by Excellent product! I was a little worried that it would be complicated to install but really it was easy just like in the video. It took me 2 hours to do it only because I kept repeating the video to make sure I was doing it right. An expert would probably do it in 30 mins. Having everything is the key. Here is a list of what you need. The watch dog sump pump system Watch dog battery which was not included in the sump pump The battery acid which was not included I with the battery purchase 1 1/2 in rubber pipe connector In my case I needed to cut the PVC pipe which was not a big deal and connecting it to the main pipeline with the rubber connector. I just used the old PVC pipe from the old sump pump. Remember to date your sump pump so that you would know to change in the future. I would say between 8-10 years should be a good benchmark. Good luck! April 27, 2013
Rated 5 out of 5 by Best Purchase Ever OMG!!!!! I couldn't of asked for anything better. Money well spent. I received a quote from a very dependable company on installing me a BATTERY BACKUP SYSTEM, and they quoted me $1700.00 installed and parts. I went to the internet and found this on the Home Depot site. Very easy to install, and does everything it said it would at half the price of my quote!!!! VERY, VERY, VERY SATISFIED...:-) November 11, 2014
Rated 4 out of 5 by peace of mind after many close calls with water this past winter/spring Product was expensive.... However the convenience of not needing to piece together an add on battery back up system made it worth it. It was very easy to install. In my case I needed an extra piece of pvc pipe and another 1 1/2 in. coupler and more cable ties to complete the job. I ended up purchasing a large Excide deep cycle(marine) battery which was much cheaper than the watch dog battery and I didn't have to mess with the acid. I just need to check the water levels in the battery every 4-6 weeks and top off with distilled water as needed. Pump is very quite and seems to work well. March 31, 2014
