Abstract
A portable water storage tank having an internal submersible pump connected to a water discharge pipe and an internal air-hydropneumatic tank also connected to the water discharge pipe; a pressure switch connected to the discharge pipe and an electrical circuit for turning the pump on and off in response to pressure variations in the water discharge pipe. A water heater in the water storage tank and a temperature sensor in the tank to activate the heater upon detection of predetermined water temperatures.
Claims9
A portable water system, comprising:
- a. a storage tank having an access cover and a water discharge pipe;
- b. a submersible pump located inside the storage tank proximate the bottom of the tank, the pump being connected to the water discharge pipe;
- c. an air-hydropneumatic tank inside the storage tank and having a connection to the water discharge pipe;
- d. a pressure switch connected to monitor the water pressure inside the water discharge pipe, and having means for activating and deactivating at predetermined pressure levels;
- and
- e. electric circuit means connected to the pressure switch and to the submersible pump, for turning the submersible pump on and off in response to pressure switch activations and deactivations.

A portable water delivery system, comprising:
- a. a water storage tank having an access cover and a water discharge outlet pipe;
- b. a flow inducer in the bottom interior of said water storage tank, said flow inducer having a plurality of inlet openings and an interior chamber;
- c. a submersible pump located inside the interior chamber of said flow inducer, said pump having a pump outlet connected to said water discharge outlet pipe;
- d. an air tank inside said water storage tank, having a connection to said water discharge outlet pipe and to said pump outlet;
- e. a pressure switch connected to respond to the water pressure in said water discharge outlet pipe, and having means for generating electrical signals at predetermined high and low pressures;
- f. electrical circuit means connected to said pressure switch and to said submersible pump, for activating and deactivating said pump in response to signals from said pressure switch;
- and
- g. water level detection means in said water storage tank, and means for signaling said electrical circuit means to shut off said pump at predetermined low levels of water detected in said water storage tank.
5 more elements
A water delivery system, comprising:
- a. a storage tank having a top opening and an access cover attachable over the opening;
- b. a water pump assembly comprising a flow inducer, a pump, and a pump drive motor, said assembly sized for insertion into said tank and removal from said tank through said top opening;
- c. an air tank insertable into said tank and connected to said pump, and a discharge pipe connected to both said air tank and said pump, said discharge pipe passing through said access cover;
- and
- d. means for monitoring the pressure of water delivered from said pump, and further means for controlling the operation of said pump in response to the monitored pressure.
