AI Technical Summary

Benefits of technology

The invention provides a combined sump pump with a new type of backup pump structure that is easy to manage, cost-effective, and convenient for customers to use, install, and overhaul. The main technical effects include reliable connection between the primary pump and backup pump, simplified pipeline installation, reduced installation volume of the backup pump, easy and reliable connection, and prevention of water backflow to another pump.

Problems solved by technology

Domestic sewage or groundwater drains into the basement pit in North American households is mainly discharged into the sewers or municipal storm drain through pumps, in the case of failure of pumps or power outages, the excess water will overflow to flood the basement to cause big economic losses.

However, at present, this type of pump on the market is complex on pipeline connecting, it requires professional plumber to install at consumers' expense, or consumers do themselves ending at an unreliable connection, which affects the promotion and use of combined pumps badly.
