SUMP PUMP WITH EMERGENCY BACKUP SYSTEM
First Claim
1. A flood control system for use in a structure having a basement floor below ground level, the system comprising:
- a sump;
a main pump positioned in said sump, said main pump being energized when a height of water within said sump is at a first level;
a secondary pump positioned in said sump, said secondary pump being raised relative to said main pump to a predetermined elevation, said secondary pump being energized when a height of water within said sump reaches a second, higher level and de-energized when a height of water within said sump drops to a third level;
a cover releasably mounted to said sump, said cover including a first section for covering said main pump and a separate second section for covering said secondary pump, at least one of said first and second sections being hingedly mounted to said sump; and
a controller operatively connected to said main pump and said secondary pump, said controller being responsive to water level within said sump to selectively energize at least one of said main pump and said secondary pump.

Abstract
A flood control system for use in a structure having a basement floor below ground level is provided. The flood control system comprises a sump, a main pump positioned in the sump, and a secondary pump positioned in the sum. The secondary pump is raised relative to the main pump to a predetermined elevation. The main pump is energized when a height of water within the sump is at a first level. The secondary pump is energized when a height of water within the sump reaches a second, higher level and is de-energized when a height of water within the sump drops to a third level. A cover is releasably mounted to the sump. The cover includes a first section for covering the main pump and a separate second section for covering the secondary pump. At least one of the first and second sections is hingedly mounted to the sump. A controller is operatively connected to the main pump and the secondary pump. The controller is responsive to water level within the sump to selectively energize at least one of the main pump and the secondary pump.

13. A flood control system for use in a structure having a basement floor below ground level, the system comprising:
-
a sump for gathering subterranean water for removal from the structure; an AC operated main pump positioned in said sump; a DC operated secondary pump positioned in said sump; an elevating member located in said sump for raising a height of said secondary pump relative to said main pump; a cover releasably mounted to said sump, said cover including a first section for covering said main pump and a separate second section for covering said secondary pump, at least one of said first and second sections being hingedly mounted to said sump; and a first discharge pipe connected to an outlet of said main pump and a separate second discharge pipe connected to an outlet of said secondary pump, said first and second discharge pipes extend through said cover and are configured to discharge to separate locations for preventing back pressure through said first and second discharge pipes. - View Dependent Claims (14, 15, 16)
