Therefore, a need exists for a new and improved booster water pressure pump which can be used for increasing residential water pressure without the limitations of the prior art. In this regard, the present invention substantially fulfills this need. In this respect, the booster water pressure pump according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of increasing water pressure.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of water pumps now present in the prior art, the present invention provides an improved booster water pressure pump, and overcomes the above-mentioned disadvantages and drawbacks of the prior art. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved booster water pressure pump and method of increasing water pressure which has all the advantages of the prior art mentioned heretofore and many novel features that result in a booster water pressure pump which is not anticipated, rendered obvious, suggested, or even implied by the prior art, either alone or in any combination thereof.
This invention was conceived to boost water pressure in homes. Where at times water pressure from the city or township is insufficient to supply increased water usage in a private dwelling.
With the increase of home construction within the cities or townships limits, water demand is on the rise. At times increased usage will drop city pressure to where it may or could interfere with daily needs of residential water customers, which include, for example, showering, flushing of toilets, or merely watering the lawn.
This invention was designed to boost or equalize the water pressure in a home to meet demand. When installed, this system will sense pressure drops in the water system by means of a pressure sensor and regulator on the output line of the system. When engaged, the system will increase water flow to meet household needs. The system is also designed to disengage when demand is met or when water is not being used. The system is also equipped with an adjustable pressure relief valve.
To attain this, the present invention essentially comprises a supply conduit, a residential conduit, a first pump having a first inlet conduit connected with the supply conduit, an outlet conduit connected with the residential conduit, a first motor for driving the first pump, a first check valve in the first inlet conduit, a throttling conduit connecting the first inlet conduit to the outlet conduit downstream of the first check valve, and a pressure switch connected with the residential conduit and transmitting a start signal for starting the first motor when the pressure in the residential conduit is less than a predetermined minimum pressure so that the first pump discharges into the residential conduit while circulating fluid through the throttling conduit. Also, the invention includes a method for increasing residential water pressure.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
The invention may also include additional valves. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.

The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description males reference to the annexed drawings wherein:
FIG. 1 is a side view of a water fixture as it may appear without the benefit of the present invention.
FIG. 2 is a side view of a water fixture as it may appear with the benefit of the present invention.
FIG. 3 is a schematic view of an embodiment of the apparatus of the present invention.



The same reference numerals refer to the same parts throughout the various figures.
While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the drawings and detailed description thereto are not intended to limit the invention to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention as defined by the appended claims.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to the drawings, and particularly to FIGS. 1–3, a preferred embodiment of the booster water pressure pump of the present invention is shown and generally designated by the reference numeral 10.
In FIG. 1, a water fixture 100 is shown. Such a typical water fixture may be found in a typical household. In FIG. 1, the water fixture is shown having a low water flow 110. The apparatus herein described may remedy such a low flow. Once remedied, as shown in FIG. 2, the water fixture 100 delivers water having a boosted flow 120.
As shown in FIG. 3, a new and improved booster water pressure pump apparatus 10 of the present invention for boosting residential water pressure is illustrated and will be described. More particularly, the improved booster water pressure pump apparatus includes a water supply conduit 12. Water supply conduit 12 has a diameter 44. Supply conduit 12 provides water flow to an inlet conduit 18. Inlet conduit 18 has a diameter 46, where the supply conduit diameter 44 may be greater than or equal to the inlet diameter 46. Inlet conduit 18 provides water flow to pump 16. Pump 16 is driven by motor 22. Motor 22 is actuated by pressure switch 28. In an embodiment, motor 22 is actuated when the water pressure falls below a user-defined lower limit. In an embodiment, a water pressure less than or equal to 65 psi will cause the pressure switch 28 to switch, thus actuating motor 22. In this manner, the pump 16 may be turned on. IN an embodiment, pump 16 is a jet-type pump. The pressure switch 28 and first motor 22 are powered from a typical household electrical system, such as a 115/230 V system. For example, a typical household receptacle using power cord 42 may be used to power the apparatus. In an embodiment, pressure switch 28 is adjustable.
Water thus flows from the inlet conduit 18, through pump 16, and into the outlet conduit 20. In the event the water pressure is above the predetermined minimum pressure, the pump 16 is merely “open” and does not accelerate nor hinder water flow therethrough. However, when the water pressure is less than the predetermined minimum pressure, the pressure switch 28 is actuated, and thus the pump 16 is turned on. The pump increases the water flow from the apparatus 10 thus increasing the pressure of the water exiting the apparatus through outlet conduit 20.
A throttling conduit 26 is arranged between the inlet conduit 46 and the outlet conduit 20, in an arrangement substantially parallel to the pump 16 as shown. Thus, water may flow through the throttling conduit 26 when the relief valve 34 arranged within the throttling conduit 26 is open. In an embodiment, relief valve 34 is adjustable.
Arranged within the inlet conduit 18 is an inlet on/off valve 32. Such a valve may be used in enabling the apparatus 10. Correspondingly, arranged within the outlet conduit 20 is an outlet on/off valve 36. When these valves are turned to their “on” positions, the apparatus is enabled. That is, water may flow through the apparatus. The apparatus is disabled when the valves are turned “off”.
Also arranged within the inlet conduit 18 is a first check valve 24. In an embodiment, check valve 24 is a spring type check valve. Check valve 24 prevents water from flowing into the supply conduit 12 from the first inlet conduit 18. Correspondingly, a third check valve 40 is arranged in the outlet conduit 20. A second check valve 30 is arranged between the supply conduit 12 and the residential conduit 14. In an embodiment, check valve 30 is a spring-type check valve.
In an embodiment, the apparatus will comprise pvc piping to ensure low cost and an apparatus that is substantially lightweight such that it may easily be transported. However, any suitably rigid, potable-water transporting conduit may be employed.
While a preferred embodiment of the booster water pressure pump has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. For example, any suitable conduit material may be used instead of the PVC described. For example, copper or steel may be used. Also, other means of preventing water from back flowing into the supply conduit may be employed instead of the check valves recited herein. Still further, the apparatus may include quick-release fittings such that the apparatus may be easily installed and uninstalled. Such fittings may reside on the inlet and outlet conduits.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
