ABSTRACT:
An elongated upstanding hollow casing is provided including an upper end water outlet and a lower end combined sand and water outlet. The casing includes a mid-height laterally outwardly opening water inlet and a central upstanding tube is disposed within the casing. The tube includes a capped lower end and its upper end is in sealed communication with the upper end water outlet. The central tube includes circumferentially and longitudinally spaced apertures formed therein intermediate the capped lower end and the upper water outlet and a thick-walled tubular body is disposed about the apertured tube. The thick-walled tubular body is constructed of porous filter material such as foam rubber and the lower end sand and water outlet includes a valve assembly operatively associated therewith for selectively opening and closing the sand and water outlet. The tubular body is fitted tightly about the apertured portions of the central tube and a protective bank extends at least substantially entirely about that portion of the tubular body with which the water inlet is registered.
