6 Questions

Q: Will the watchdog big dog bwd12120c pump out water at 20ft.
by Jim W. from Minnesota on March 24, 2012

A: The max vertical height the Big Dog can pump out is around 13-15’. Anything over 13', it will not be able to pump reliably. It can also usually do around 25’ sideways provided the horizontal run does not slant upwards at all.
by Jim, Product Expert

Q: Can this Big Dog System be run using 2 batteries in series for longer run time?
by Howard Mark from Pennsylvania on May 20, 2011

A: Yes, the Big Dog is the only Basement Watchdog backup system that will allow 2 batteries to be connected in PARALLEL to provide a longer run time.
by Jim, Product Expert

Q: I currently have the small emergency backup sump pump (watchdog), which no longer works. I am looking to replace it with watchdog big dog backup system. Would the discharge pipe have to be modified to accommodate the new pump? Also, I just replaced the (6 hour)battery last year and it seems fine. Would it be possible to use this battery with the more powerful pump?
by Bill from Ohio on March 05, 2011

A: All of the Basement Watchdog Backup Pumps we carry accept a 1 1/2" discharge pipe, incuding the Big Dog. The battery required for the Big Dog is the 30HDC140S
will run the Big Dog system for up to 7 1/2 hours.
by Jim, Product Expert

Q: I have pumps and only want the battery backup electronic system. can i buy just the battery backup without the pump?
by Bob Braga from Massachusetts on February 12, 2011

A: We only sell the complete systems. You might try contacting the manufacturer @ (800) 991-0466 for more information about individual parts.
by Jim, Product Expert

Q: Do I need to leave my battery backup system charging at all times?
by Patrick Mcclone from Wisconsin on January 03, 2011

A: To be completely sure your backup system is fully functional during a power outage or weather event, these systems need to stay plugged in at all times.

by Jim, Product Expert

Q: how many hours backup does this provide in case the power goes out. we are looking for a 24 hour back up pump.
by Diana from New Jersey on January 03, 2011

A: This system does not include a battery, and that is what determines the hours of backup a system can provide. There is also the factor of how often a system is running that determines the amount of backup time.

Why It Is Called the Big Dog

The "Emergency" and "Special" models contain some great features. But, the "Big Dog" takes the concept to a whole new level.

It features an extremely powerful 20-amp battery charger that can recharge while it's pumping. Plus, you can connect a second battery to the "Big Dog" to double its run time.

Best of all, it turns on weekly, actively looking for vulnerabilities. For example, the "Big Dog" can actually sense if the backup sump pump is clogged or broken.
