Product Overview

  • Boasts an easy-to-use control panel
  • Thermoplastic construction for corrosion resistance
  • Features a dual float switch
When you simply want what’s best for your basement, The Basement Watchdog Big Dog Connect is the system for you. It will protect your basement from a power outage, primary pump or float failure, provide extra pumping capacity when needed, and can even take over for your primary pump indefinitely when AC power is available. It will sound an audible alarm and give a visual warning on the control box pinpointing needed maintenance or irregularities with the battery, pump, or power conditions. This system is part of The Basement Watchdog Connect line, giving it the ability to communicate with a Basement Watchdog Connect Module (WiFi module BW-WiFi or Home Automation Module BW-HZM). When connected to The Basement Watchdog WiFi Module the system will send a text, email alert or a notification through the Basement Watchdog App to alert of any irregularities. The Big Dog is designed with reliability in mind. With its dual float switch, easy to understand alarms, weekly self-test, 2200 GPH pump, and long-lasting battery, you can feel safe that The Basement Watchdog is watching out for you.
  • Pumps 2,200 GPH at 10 ft. lift and 3,500 GPH at 0 ft. lift
  • USB port allows for connection to a basement watchdog module (BW-WiFi or BW-HZM), giving you real time alerts (text, email, or through the basement watchdog app)
  • Remote terminal allows the ability to connect with a home security system, or other device
  • User friendly control panel detects irregularities, sounds an alarm, and pinpoints problems and solutions
  • Powerful 20 Amp charger charges the battery quickly and shuts off completely to prolong battery life

Can this be used as a primary pump?

Asked by: JM
Although the "BigDog" can run off AC and DC (Battery) power, I would not recommend using this as your only pump. Basement Watchdog does make some very good primary pumps. Two pumps are better than one.

Where do you add the water when the alarm indicates water is needed?

Asked by: Sue
One the top of the battery. The top of the battery has 6 caps (cells). Remove each cap and add distilled water to each cell, enough to cover the plates. Please read the instructions before attempting. Safety first! The instructions are really good with lots of pictures.

It was an easy replacement installation, and worked fine. I do recommend the sealed battery - adding your own acid is an awkward process. Sealed battery has a shorter usage rating, but I have a portable generator, so I'm not too worried about keeping it going in a prolonged power outage.

I was pleased to find that Home Depot also carried a module that connects to your home WiFi that alerts you via an app when the pump is activated or if there is a power failure.
