Modular sump pump pit assembly

Abstract

The disclosed sump pump pit is modular, being formed from substantial planar lightweight top, bottom and side walls that when disassembled can be carried compactly stacked on one another to an intended sump hole, and can then be assembled and secured together as the rigid pit defining an enclosure sized to hold at least one sump pump (preferably two sump pumps side-by-side). Cooperating tongue and groove configurations on the side wall edges interlock these components in a tubular configuration, and the end edges of the side walls can be fitted into and secured in channels in the top and bottom walls, making the pit rigid. The pit walls are perforated for communicating the sump hole with the pit enclosure. Piping extended through the top wall allows water to be pumped from the sump hole via the pit pump(s).

Description

RELATED APPLICATION[0001]This application is related to a Provisional Application from the same inventors, filed on Feb. 22, 2008 and possibly having App. No. 61 / 011,831 (filing receipt No. 6756 received by attorney having this number, except identifying a different invention which corresponds to a second Patent Application concurrently filed by the same attorney, in fact in the same envelope. This attorney to date has received no filing receipt for this second Application invention, although the USPTO has collected the $105 and $515 filing fees for these Applications.BACKGROUND OF THE INVENTION[0002]Buildings typically have a perimeter footing buried in the ground below the frost line, with an upstanding perimeter foundation supported thereon to rise above the ground. Building side walls are supported on the foundation (or footing) above the ground level. A building floor (basement, crawl space or first floor) typically is defined inside of the foundation perimeter, frequently comp...

AI Technical Summary

Benefits of technology

[0007]A general object of this invention includes providing a sump pump pit structure comprised of multiple components that can be shipped disassembled and nested together, compactly and economically, to an end user, whereupon the user can then easily carry these components to proximity of the ultimate use site and assemble them into a sturdy unitary sump pit.

Problems solved by technology

However, adding a sump pump system to an existing building has been significantly more difficult, such as where the sump hole might have to be dug in tight quarters of a crawl space.

Specifically, many crawl spaces have only limited height clearance between the floor and overlying joists and have a limited size access opening through which a one-piece sump pit, possibly 20 inches OD and 26 inches long, must be passed and manipulated into the prepared hole.
