  • Sump pit having disassemblable upper and lower tank portions
    Patent number: 10343840
    Abstract: A collection tank for mounting under a floor of a building for collecting water from an area under the floor comprises upper and lower tank portions removably securable by rotatable mating of tabs in cavities. Additionally, a pump platform of the tank is formed by a plurality of ridges which form therebetween a channel so that the water is collectable in the tank between the ridges. Furthermore, the upper and lower tank portions are separable, and a width of the top of the upper tank portion is smaller than a width of the open top of the lower tank portion such that the upper tank portion can be received in the lower tank portion in an inverted orientation, in which the collection tank is inoperable for collecting the water, so as to decrease a height of the collection tank.
