Abstract
A pitless drainage system for removing water from the footings of a structure. A vertical riser is located outside the structure, extending from above the ground to a subterranean location proximate a footing drain. A well collector extends downwardly from the vertical riser, having a series of ingress slots to allow water to flow therethrough. A submergible torpedo pump is located in the well collector, and upper and lower pump activation controls deactivate and activate the pump depending on the water level in the vertical riser. A over level pump activation is provided, as well, in case the upper level pump activation fails.
Claims12
A pitless drainage system for removing water from at least a portion of a footing drain in which water is collected at a subterranean location, said system comprising:
- a. a vertical riser extending in a substantially vertical orientation from a top at an upper elevation above ground to a bottom at a lower elevation at the subterranean location, the riser being located proximate the footing drain,
- b. a well collector in the vertical riser at the bottom, the well collector having ingresses allowing water to follow therethrough,
- c. a protective cap on the riser at the top,
- d. a submersible pump in the well collector, and
- e. water level control in the vertical riser, comprising
- i. an upper level pump activation repositionable within the vertical riser, and
- ii. a lower level pump activation repositionable within the vertical riser.
A pitless drainage system for removing water from at least a portion of a footing drain in which water is collected at a subterranean location, said system comprising:
- a. a tubular vertical riser extending in a substantially vertical orientation from an upper location above ground to a lower location proximate the footing drain at said subterranean location,
- b. a well collector extending from the vertical riser, the well collector having ingresses for water comprising elongated, space vertical slots,
- c. a removable protective cap secured atop the vertical riser,
- d. a submersible pump in the well collector, and
- e. water level control in the vertical riser, comprising
- i. an upper level pump activation sensor tube repositionable within the vertical riser,
- ii. a lower level pump activation sensor tube repositionable within the vertical riser, and
- iii. an over level pump activation sensor tube.
