Rated 5.0 out of 5.0 by Hurricane Sandy Bought it about a year ago and haven't needed it. Then hurricane Sandy hit us in New Jersey. I wasn't sure how the system was going to work once the power went out. I was worried to got to sleep because I wasn't sure how it was going to work. I checked it every half hour because my basement floods real quick. After awhile I fell asleep and woke up the next morning and it worked great, not a drop of water in the basement. Once I hooked up the generator I was able to power the pump with electric. Bit it is one of the best investments I made. It really relieved a lot of stress. If you are thinking about buying one, don't hesitate go and get it! October 31, 2012
Rated 5.0 out of 5.0 by Delivered Quickly Moved into a older home and the existing sump pump was on its last leg. As the hard rains kept coming I feared either a power failier or a pump failier. So late on a Saturday night as the thunder storms pounded and the TV constantly beeped, sending emergency flood warnings while the old pump rattled and strained; I went online (1/3 hp watchdog combo is only available online) to order the pump. Luckily the old pump made it through the night, and the new one arrived that Tuesday afternoon (2 days for delivery, that's fast.) The Install was easy, it took more time to shop vac out all the debris in the bottom of the sump pit then it was to install the pump itself. I Decided to go with a maintenance free deep cycle battery instead of the recommended watchdog battery, (horrible reviews online about their battery, not their pumps). As per instructions I attached the battery acid probe to the positive terminal of the battery. So far the pump runs very well and is super quiet, especially when compared to the old concrete mixer that was there originally. If the pump doesn't last I will surely review this product again in the future. I would definitely recommend this pump at this point to anyone looking to install a new primary pump and would like the added confidence in knowing that if the power or the main pump fails, you won't be wadding in water thinking (duhh, I probably should have gotten a battery back up pump.)

Rated 5.0 out of 5.0 by Sump Pump Good instructions, easy to install. If you you your own battery make sure it has a good charge on it before connecting up to the trickle charger they provide or the system will alarm and the trickle charger won't charge the battery quick enough. December 31, 2014
Rated 5.0 out of 5.0 by Excellent Purchase This turned out to be a pleasant surprise. It was actually as easy to install this pump as advertised! Solid design, great features, with a primary and a secondary pump plus battery backup. May 5, 2015
Rated 5.0 out of 5.0 by Great product I installed it in one hour, it took me more time to go to HD to get a rubber coupling. I filled up my sump pit with water, while keeping the main pump unplugged, the secondary pump came on and pumped out all the water, our height was 12 feet, no problems. I am very happy with this product, and strongly endorse all to consider this, before wasting time and money + energy and plumbing costs with the others. Regards and happy holidays December 18, 2011
Rated 5.0 out of 5.0 by Wonderful customer service Our old pump died overnight in a big rainstorm, we got up in the morning to find 3 inches of water in the basement. We went out and bought this pump to quickly replace the dead one. It installed really easily and was back working right away! We only needed a hacksaw (to adjust the length of the discharge pipe) and a screwdriver (to attach the pump). We decided to get this one because of the ease of installing and the inclusion of the battery back-up (previously we were stuck in a power outage and had to bail the sump pit by hand for a day, really didn't want to worry about that again in the future). Later in the day when the cleanup crew came, they knocked a piece of their equipment into the sump pit, smashing the pit cover and destroying both float switches (both the primary and the battery back-up). I called up the manufacturer's technical support and they overnight FedEx-ed me replacement floats at no charge! Wonderful customer service! May 10, 2012
Rated 5.0 out of 5.0 by Basement Watchdog install Primary pump is very powerful and fast. Back-up is slower but works as well as my old primary pump that I replaced. I have wanted a battery backup set up for quite some time and I'm very happy with the performance and quality of this dual unit. Installation instructions could have been written better to guide DIY's like myself but I managed through OK. January 28, 2014
Rated 2.0 out of 5.0 by Good systym Until!!!! I have had this system for more than 3 years. It worked great until about 6 months after the warranty expired. Since then I have had to mess with often. First the float switch went out and I was told the warranty expired so money out of pocket (about $40 bucks) no big deal. Now 2/21/14 I go downstairs to check on it and I hear a clicking sound and all the lights are lit on the back up controller. So I have since unplugged the back up pump and disconnected the battery and charge it with a charger! February 23, 2014
