Navigating These Challenging Times Together

First, we want to thank you for your support during this difficult time. Like everyone else we are just trying to take things one day at a time and get through this the best we can. We'd like to share some information with you to help you stay updated with what's going on at Life and Home in the coming days.

Steps We're Taking:
Our offices are all currently set up to work from home to help stop the spread of COVID-19. At our warehouse, we are increasing efforts to disinfect high-touch and high-trafficked areas throughout the day and increasing daily cleaning routines. We are also making sure all employees have up-to-date information on how to stay healthy and what preventative measures should be taken and the ability to stay home if they are feeling unwell.

Updated Return Policy:
We have temporarily updated our return policy from 30 days to 45 days. Our goal is that you're completely satisfied with your purchase. If for any reason, you are not satisfied, simply return your purchase in its original packaging, with your original receipt/email confirmation within 45 days from the purchase date.

You may experience delays in shipping as we are taking the necessary precautions to protect you and our team. We are still working hard to get in-stock items shipped within 24 hours. Few items may temporarily have longer fulfillment times.

Customer Service:
Our customer service team is working hard to help all customers as quickly as possible. Due to technical difficulties, you may experience interrupted calls. In the event this occurs, please email us at or message our chat here on the site. We apologize for any inconvenience and thank you for your understanding.

Thank you again for your support.

Combination Primary & Battery Backup Sump Pump System Includes a Basement Watchdog AC pump and a Basement Watchdog battery backup system.

The Basement Watchdog Combination sump pump system is designed to provide both primary and backup pumping capabilities. The primary pump will operate as long as it is receiving AC power. If the power is interrupted, or more water is coming into the sump than the AC pump can handle, the backup sump pump will begin pumping automatically. The backup system has unique monitoring features that diagnose a problem and sound an alarm. A light on the display panel of the control unit will indicate the cause of the alarm and the corrective action. The two systems have been preassembled for easy installation.


  • Already assembled for easy installation
  • Compact footprint fits in any size sump pit
  • Dual float switches provide dependable activation for each pump
  • Unique monitoring controller sounds an alarm if maintenance is needed
  • Battery (Catalog ID: 40641333) and acid sold separately.


  • Backup System: Special
  • Backup GPH at 10': 1730 GPH
  • AC Pump HP: 1/2 HP

Dual Float Switches: Both Basement Watchdog Pumps have dual redundant floats on each switch. Should one float fail to activate the pump, the second float takes over. The result...added reliability.

Installation is easy: Cut discharge pipe and remove old unit. Place new unit in sump pit. Connect combination unit to discharge pipe with rubber union. Connect backup controller and battery. Plug in both controllers. System comes with detailed installation instructions complete with pictures and diagrams.
