A sump basin includes an upstanding wall a base and a top. A sensor in the form, e.g., of a float switch extends into the basin and is operable to actuate a pump to remove collective wastewater from the basin. The sensor depends from a sensor support that is supported distally within the basin in a vertical manner and is supported proximately within the basin in a horizontal manner, with securement of the sensor support not requiring traversal of the basin top and with the distal basin support not needing to be accessed vertically through a pump access aperture in the top. ## Claims ### Claim 1 A pump control comprising: a sensor operable to communicate a level of wastewater in a container to a pump; a sensor support, the sensor secured to the sensor support, the sensor support comprising: a longitudinal extension having a distal end portion and a proximal end portion, with a longitudinal axis extending therebetween; a distal sensor support arm extending radially outward from the distal end portion of the longitudinal extension relative to the longitudinal axis of the longitudinal extension; and a proximal sensor support comprising a spring pin extending axially along the longitudinal axis and an opening, the spring pin of the proximal sensor support having a terminal end axially moveable relative to the opening along the longitudinal axis to protrude beyond a proximal end surface of the proximal end portion of the longitudinal extension. ### Claim 2 (depends on 1) The pump control of claim 1, wherein said sensor support further comprising a spring providing a biasing force to bias said spring pin away from said distal sensor support arm to a first position, said spring pin actuatable against the biasing force of the spring toward said distal sensor support arm to a second position. ### Claim 3 (depends on 1) The pump control of claim 1, wherein said sensor comprises a float switch tethered to said sensor support. ### Claim 4 (depends on 1) The pump control of claim 1, wherein said sensor comprises a plurality of float switches tethered to said sensor support. ### Claim 5 (depends on 1) The pump control of claim 1, wherein the distal sensor support arm includes an aperture configured to be piloted into engagement with an extension in a sump, and the spring pin being configured to be resiliently engaged with a recess. ### Claim 6 (depends on 1) The pump control of claim 1, wherein said longitudinal extension is an elongate rigid structure. ### Claim 7 (depends on 1) The pump control of claim 1, wherein said distal sensor support arm is an elongate rigid structure. ### Claim 8 (depends on 2) The pump control of claim 2, wherein said spring pin further comprises an actuator pin configured to be manually engaged to actuate said spring pin against the biasing force of the spring. ### Claim 9 A pump control comprising: a sensor operable to communicate a level of wastewater in a container to a pump; a sensor support, comprising: a longitudinal extension having a distal end portion and a proximal end portion, with a longitudinal axis extending therebetween; a distal sensor support arm extending radially outward from the distal end portion of the longitudinal extension relative to the longitudinal axis of the longitudinal extension; and a proximal sensor support comprising a spring pin extending axially along the longitudinal axis, the spring pin of the proximal sensor support having a terminal end axially moveable relative to the proximal sensor support along the longitudinal axis to protrude beyond a proximal end surface of the proximal end portion of the longitudinal extensions; wherein the sensor is attached to the sensor support between the distal end portion and the proximal end portion of the longitudinal extension. ### Claim 10 A sump pump control, comprising: an extension having a longitudinal axis; a support arm extending radially outward from the extension and including an aperture to receive a portion of a lower support of a basin containing fluid to couple the extension to the lower support; a spring pin positioned within an upper end of the extension for movement along the longitudinal axis between a retracted position permitting the extension to pivot about the portion of the lower support below an undersurface of a top of the basin and an extended position wherein the spring pin engages a recess in the undersurface to position the extension; and at least one sensor attached to the extension and operable to communicate a level of the fluid in the basin to a pump.
