ABSTRACT:
An end of an inlet tube communicates through a tank wall with a water supply and an inner end of the inlet tube communicates through a float controlled valve with a generally vertically downwardly extending outlet tube. Thus, the tank water level through the float controls closing and opening of the valve admitting water through the inlet tube, through the valve and down the outlet tube flowing into the tank from the outlet tube lower end. The outlet tube is selectively vertically adjustable to adapt to various depths of tank by being formed of telescoped parts normally retaining a determined telescoping by a projection of one part being radially interengaged in a groove of the other part. Depending on the particular construction, the tube part telescoping may be selectively varied by either relative rotation between the parts or by disengaging and reengaging the interengagement between the parts. Through a slot and lock collar arrangement, the tube parts may be totally telescopically separated.
