A deep well pipe water release valve is described including a valve assembly comprising a body defining an upright passage therethrough having upper and lower ends. The body includes a lateral port having an inner end opening into the passage intermediate the upper and lower ends and an outer end adapted for sealed communication with the interior of the lower end portion of a deep well delivery pipe disposed in a deep well, a valve member slidably received in the passage and upwardly displaceable from the latter. The valve member is shiftable in the passage to a position spanning across the port, seal means establishing a sliding fluidtight seal between the valve member and the body both above and below the port, and vertical pull means including a lower end terminal portion adapted for anchored securement to a motor and pump assembly within the deep well below the body and an intermediate height lower end portion above the lower terminal end portion operably connected to the valve member for upward displacement of the latter from the upper end of the passage upon an upward pull on the upper end portion of the pull member and with the operable connection of the pull member with the valve member being sufficiently spaced above the lower terminal end of the pull member to enable upward displacement of the valve member from the upper end of the passage before a continued upward pull on the pull member is effective to apply an upward pull on the motor and pump assembly.
