  • Patent number: 8413675
    Abstract: A Yard Hydrant Made Easy has a riser with a slip connection, called a pitless adapter, attached directly to the side of the riser, below freeze level. The water supply is connected to the outside section of the pitless adapter and a yard hydrant is attached to the inside removable section of the pitless adapter. This hollow riser and slip connection allows for easy removal and replacement of a yard hydrant, without the need of any future excavation, busting of concrete, or tearing up of landscaped areas. A seepage section may be incorporated at the base of the riser to allow a yard hydrant to drain out without ever coming in contact with soil. This prevents any chance of the drain hole, at the base of the yard hydrant, becoming stopped up and causing the hydrant to freeze. A dual check valve backflow preventer may be installed at the base of the hydrant.

Movement of the operating rod in one direction disengages the plug from the valve seat permitting water to flow through the casing and an opening of a set screw forcing a ball against an O-ring seal. Movement of the operating rod in an opposite direction causes alignment of a radial opening in the operating coupling with a passageway in the operating screw. The operating rod engages the valve seat preventing water from flowing through the casing and allowing the ball to fall away from the O-ring seal. Air enters a chamber of the operating screw thereby draining water from the chamber and out of the radial opening of the operating coupling.

  • Patent number: 6899120
    Abstract: A yard hydrant has an elongated wet pipe with a plunger that seals against the inside of a well casing. Lifting a pivoting handle at the top of the wet pipe lowers the wet pipe which opens a normally closed supply valve. Pressurized water can then flow up the wet pipe and out of a nozzle head mounted to the upper end of the wet pipe. Lowering the handle pulls the wet pipe upward, thereby clearing it from the supply valve which is spring biased to shut off the water supply. The handle has a cam that positively actuates a normally closed anti-siphon valve so that water left in the wet pipe can fall under gravity to a collection chamber within the well casing beneath the piston. Lifting the handle again lowers the wet pipe and forces the water in the collection chamber back up the wet pipe. At the same time, the anti-siphon valve will close and the wet pipe re-opens the supply valve.

A hollow valve fitting is rigidly secured to the interior end of the inlet tube for a connection to a source of pressurized fluid. A movable ball is located with a fluid conduit that extends from the interior of the inlet tube to the location of the potable water source. When the water pressure inside the inlet tube increases because of the presence of ice, the high pressure of such water moves the ball to open fluid flow of the high pressure fluid to the source of potable water which will be at a lower pressure, thus reducing the fluid pressure within the inlet tube and saving it from rupture.

  • Patent number: 6394125
    Abstract: A combination sheath and frost-resistant wall hydrant include a hydrant having a wall-penetrating conduit and intermediate wall bracket. There is an internal valve seat between the bracket and indoor or inlet end, and so is located in a presumptively warm indoor climate and spaced back from the wall and/or outdoors so as to reduce chances of freezing outdoor temperatures freezing water stopped behind the valve seat. The sheath telescopes over the hydrant's inlet end until the sheath's leading end mates against the hydrant's bracket. The leading end is vented for venting leakwater from the hydrant outdoors and not indoors in cases if the hydrant bursts by freezing because water got stopped in the conduit between the valve seat and outlet and failed to drain despite an open outlet. The sheath's trailing end seals onto the hydrant somewhere behind the valve seat.

  • Patent number: 6279594
    Abstract: An upright cylindrical valve body has an inlet port axially aligned with an outlet port. A valve member is retained for reciprocal movement into and out of engagement with a valve seat axial aligned with fluid flow between the inlet and outlet ports. A relief port positioned adjacent to the outlet port exhausts fluid that remains in the valve above the valve seat after it is closed. The valve member is normally maintained in a closed position. Fluid flow into the inlet port actuates the valve. A portion of the fluid flowing through the valve chamber is diverted through passageways by a pair of remote controlled solenoid valves to open the valve. When it is desired to close the valve, the solenoid valves are actuated to evacuate fluid internally within the valve so that the valve member is returned to a closed position. A relief valve in the outlet port exhausts fluid from the upper end of the valve when the fluid pressure falls below a preselected magnitude.

  • Patent number: 6116265
    Abstract: A freeze-proof hydrant has a hollow, tubular housing adapted to be buried in the ground in a vertical orientation so that its upper end is approximately even with the surface of the ground and its lower end is below the local frost line. A base fitting at the lower end of the housing is connected to an underground pipe and has an internal shut-off valve for controlling the flow of water out of the underground pipe. The lower end of a removable standpipe has a threaded fitting which mates with the base fitting in a manner that opens the shut-off valve when the standpipe is screwed into connection with the base fitting. The standpipe projects upwardly through the housing to a point above ground level and terminates in a faucet. When the standpipe is inserted downwardly into the housing and screwed into connection with the base fitting, the shut-off valve in the base fitting automatically opens so that water flows upwardly into the standpipe and the faucet may be operated to deliver water as desired.
