      The newly upgraded Basement Watchdog Special builds upon decades of reliability and adds even more features to protect your home from flooding. This battery-operated sump pump system is designed as an emergency backup to support the primary AC sump pump. It automatically begins pumping any time the existing sump pump fails. Easy to use controller sounds an alarm, illuminates a warning light, and describes what to do for maintenance. For added reliability, the float switch has, not one, but two floats. Should one float fail to operate, the second float automatically activates the pump. Basement Watchdog backup systems will pump during a power outage, main sump pump failure, primary float switch failure or if excess water is entering the sump pit. This new system now includes a weekly self-test of the pump, compatibility with maintenance-free AGM batteries, an improved charging and monitoring system and a remote terminal for easy connection to a security system, auto dialer or other similar device.

      • Pumps 1,730 GPH at 10 ft. lift to empty the sump pit in seconds and 2,500 GPH at 0 ft. of lift
      • Peace of mind when away from home, remote terminal allows the ability to communicate with an auto dialer, home security system or other device, to alert you to problems or required maintenance
      • Dual float switch provides 2X the protection
      • Runs weekly pump cycles to check for proper operation and to exercise the pump
      • Provides days of intermittent pumping power on a single battery charge
      • Fluid sensor monitors fluid level of the battery

      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.
