WATER PRESSURE SYSTEM WITH PRESSURE TANK INSTALLED WITHIN WELL CASING OF WELL
First Claim
1. A water pressure system comprising:
- a submersible pump for pumping water from a water bearing aquifer;
a pressure tank installed in a well casing of the water pressure system, and connected to the submersible pump with a drop pipe, the pressure tank including an inlet end, an outlet end, and an outer sidewall with a flexible diaphragm bladder located within the outer sidewall of the tank that is fillable with water from the submersible pump for storing a reserve of water; and
a relief valve and a flow control valve installed between the submersible pump and the pressure tank.

Abstract
A water pressure system includes a pressure tank installed underground within the well casing of a well. The water pressure system includes a submersible pump connected to the inlet of the pressure tank by a drop pipe. The outlet of the pressure tank is connected to a second drop pipe and in turn to a discharge pipe for distribution of pressurized water to a house or other building. A pressure switch is connected to the pressure tank for controlling the submersible pump. The pressure tank includes an outer sidewall with an inlet end and an outlet end. A flexible diaphragm bladder located within the outer sidewall is connected between the inlet and outlet of the tank. In a first embodiment, a tube extends through the center of the bladder between an inlet opening and an outlet opening. The tube has a plurality of holes therein to allow water to flow into and out of the flexible bladder. Pressurized air fills the space between the bladder and the outer sidewall to pressurize the water in the bladder. The pressure tank may be used in combination with a flow control valve, a relief valve, a flow control valve incorporating a relief valve, a standard submersible pump, and/or a variable speed submersible pump to provide and maintain a constant flow of water at a constant pressure through the system.

10. A water pressure system for use with underground water wells comprising:
-
a submersible pump installed in an underground well of a water pressure system;
a first drop pipe having a first end and a second end opposite the first end, the first end connected to the submersible pump for pumping water from a water bearing aquifer;
a relief valve and a flow control valve connected to the second end of the first drop pipe to maintain the flow of water in the system at a constant pressure and relieve pressure from the flow control valve;
a pressure tank installed in a well casing of the water pressure system, and connected to the second end of the first drop pipe, the pressure tank including an inlet end connected to the flow control valve, an outlet end, and an outer sidewall with a flexible diaphragm bladder located within the outer sidewall of the tank that is fillable with water from the submersible pump for storing a reserve of water;
a second drop pipe having a first end and a second end opposite the first end, with the first end connected to the outlet end of the pressure tank; and
a pitless adapter having an inlet connected to the second end of the second drop pipe, and an outlet connected to a discharge pipe. - View Dependent Claims (11)

21. A pressure tank comprising:
-
an outer sidewall with an inlet end and an outlet end;
a flexible diaphragm bladder separating an air chamber from a liquid chamber;
a confining tube located between the outer sidewall and the flexible diaphragm bladder for supporting and preventing the bladder from over expanding and sealing off liquid flow between the bladder and the outer sidewall; and
a valve for pressurizing the air chamber;
wherein the confining tube allows the flow of liquid around the outside of the bladder from the inlet end of the pressure tank through the outlet end of the pressure tank.
