SAMPLING DEVICE FOR SEPTIC TANKS Abstract A transparent tube is provided with a closure plate at its lower end with the plate including a resilient pad for sealing engagement with the tube end. A plate control rod extends lengthwise along the tube and ter- minates upwardly in a handle which is perpendicularly disposed on the control rod in the same direction as the closure plabe to permit handle to serve as an indi- cator of the open or closed status of the submerged end of the tube. A spring component biases the control rod and closure plate upwardly to seal the tube lower end thereby confining the vertical cross sectional sample in the tube during sample evaluation.
