Rated 5 out of 5 by Saved the day 4/28/2011 Bought in Sept 2010 and had it installed professionally for a total cost of about $600 including the installation cost of $200. Friends and family thought I was nutts spending that much! Well, it's been raining like crazy on and off for weeks and the AC sump pump has been cycling every 1 minute or so running 30 seconds to handle the water volume. Guess what? A power failure today, 4/28/2011, at around 2am during another heavy rain woke me up to an alarm. I freaked, thinking it was the floor water alarm I had installed indicating a sump overflow until I realized it was a power failure. I don't have sewers and I've have to bucket water out of the basement before to catch any overflow. Happily, it was the "Watch Dog" indicating it was functioning as designed. Long and short of it. The power failure lasted 3+ hours and the "Watch Dog" cycled every 40+ seconds for 25 seconds. I timed it, since I was still skeptical and was prepared to bucket again in the event of it's failure... Nope, worked like a champ! I figure that it pumped out well over 1800+ gallons of water at a 10ft lift that I'd would have had to bucket out myself from the basement or be standing in trying to get things off the basement floor. This one usage alone paid for itself in probable water damage, wear-and-tear on me, and peace of mind knowing it does the job it's advertised to do. If there are any battery issues, as others have suggested, I'll deal with them later BUT right now it's the best $600 I've spent to handle my basement sump pump concerns. April 28, 2011
Rated 4 out of 5 by Replacement for Old Unit The unit is very easy to install. I like that the control unit is now part of the battery cover and is much smaller than the old Watchdog control box which went bad after 12-15 years. The only comment I have is that the alarm for the main pump going off sounds daily and has to be manually turned off. I am using this pump as a main pump and it operates many times daily. I have two sump pumps on line at all times. The Watchdog products are of great quality and very reliable June 8, 2014
Rated 4 out of 5 by Does the job it needs to do. We purchased our battery back up sump 2 yrs ago. We live 1 mile from the Ohio river. When the river comes up ground water is still being pumped forseveral days even after it goes down. During a current power interuption, that lasted for 3 days do to storms the back up sump kept up with the job. Rain water and ground water. Beats having to sleep in the floor and bail water to keep your home dry! March 20, 2011
Rated 1 out of 5 by Failed first time it was needed I have a Basement Watchdog Special BWSP. It’s been installed about 18 months. We had bad rain storms today and my main sump could not keep up with the amount of water in the pit. This wonderful system failed to start. The first it was ever needed! The switch worked and the pump light illuminated but the pump itself did not start. I have checked all the connection, the pump is connected on the back of the control unit. The pump was fully tested at the time of installation and at that time, activating the float switch started the pump. As a result my basement flooded. Thanks for a wonderful system...NOT June 19, 2009
Rated 4 out of 5 by You have to use a Watchdog battery with this system The system works fine, but you must use their battery to prevent getting a battery fail warning alarm. October 18, 2011
