AI Technical Summary

Benefits of technology

[0006]The main technical problem to be solved by the invention is to provide a combined sump pump with a new type of backup pump structure, which is easy for management, cost saving and convenient for customers to use, install and overhaul.

[0017]The beneficial effect of the invention is: The present invention indicates that a combined sump pump with a new type of backup pump structure has the following advantages:

[0018]1. The primary pump and the backup pump are directly connected by a three-way straight pipe or other pipeline connection device, the various complex pipeline connection devices are molded into a whole, and the connection parts are integrated into an integrated part which makes connection more reliable.

[0019]2. The combined sump pump disclosed by the present invention, the pipeline installation is simple, and the installation volume of the backup pump was greatly reduced.

[0022]5. Integrated check valve structure, easy and reliable connection, while the primary pump or backup pump are operating, the water will not backflow to another pump.

[0023]6. The present invention provides a combined sump pump with a new type of backup pump structure, which is easy for management, cost saving and convenient for customers to use, install and overhaul.

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.
