摘要： A whole home water appliance system includes controller circuitry, a primary sump pump driven by an electric motor, and a secondary sump pump driven with a flow of water. The system also includes a water control actuator operable as a water main control device for a domestic water distribution network and a flow meter to measure the flow of municipal water supplied to the network. The controller circuitry selectively energizes the primary sump pump to extract liquid from a sump pit based on a liquid level in the sump pit. The secondary sump pump independently controlled by a hydraulic level sensor to extract liquid from the sump pit. The water control actuator controlled by the controller circuitry to shut off a municipal water supply to the domestic water distribution network in response to detection of a leak. Communication circuitry included in the whole home water appliance may wirelessly communicate.

摘要： Disclosed embodiments concern a system and method for extracting water from a water well using a vacuum-assisted technique. Particular embodiments of the system concern using a water well with a well casing, a casing seal and a water pump within the well, and a water tank, a compressor, and a heat exchanger above ground to withdraw water from the well. In particular embodiments, the casing seal is positioned over the well casing, to which the compressor is fluidly coupled to create a reduced pressure within the well and draw water into the well. In particular embodiments, the system can be used during an entire pumping season, thus providing the ability to extract water and/or increase water extraction from the ground during dry parts of the year and/or freezing parts of the year.

摘要： Vent cap assembly for a monitoring well permits venting from a well riser pipe while positively preventing contamination of the well by vandals. Tabs having apertures are integrally attached to the pipe and to an axially elongated vent cap. A padlock may be placed through the apertures to prevent unauthorized removal of the cap, but whether or not the cap is locked, the tab on the riser pipe causes the inner end surface of the cap to be spaced slightly above the riser pipe to insure that venting will always be possible.

摘要： A power shift transmission having a fluid pressure control system having an intake screen and level control located centrally in the bottom of the sump and a pump and regulator valve supplying pressure to the shift control system and to a sump oil level control. The sump oil level control has a small float controlling a relay valve to control an oil level control valve connecting an elevated oil reservoir for gravity feed to fill the sump and pressure return to the reservoir to dump the sump. When the transmission input and pump is not driven, there is no pressure in the chambers at opposite ends of the differential land area level valve and balanced springs hold the level valve in a central closed position blocking flow to and from the reservoir, to the sump and from the pressure line so the oil level control is inoperative. When the transmission input is driven, a small flow of line pressure is supplied through an inlet restriction to each chamber. When the oil level is low, a miniature float provides a small force to close the miniature relay valve closing a restricted exhaust from the chamber at the larger area land so equal pressures in the chambers act on the differential land area to move the level valve to the fill position closing the supply pressure port and providing a full flow connection from the reservoir for gravity feed at a low volume rate of flow to the sump. When the oil level is high the float permits the pressure to open the relay valve and the restricted exhaust reduces the pressure in the larger area chamber to move the level valve to dump position closing the sump port and connecting a restricted supply pressure branch to the reservoir so the transmission pump delivers fluid at the same low volume rate of flow from the sump to the reservoir to reduce the oil level. In a modification a level indicating thermistor controls a solenoid controlled relay valve similarly controlling the oil level valve.

摘要： An economical easily installable and easily removable seal assembly for use on water well casings comprises a dome having a central shaft threaded through a lower flange means so that rotation of the shaft compresses a rubber ring between the flange means and a lower rim of the dome, radially expanding the ring to grip the inside of a well casing with uniform pressure around the periphery of the ring, and also compresses an upper ring between the dome and the shaft.
