## Background
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a pool/spa filter saver system and more particularly pertains to spraying the interior surface of a cylindrical paper filter to clean the filter of debris between uses of the filter, the spraying and cleaning being done in a safe, convenient and economical manner.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of filter systems of known designs and configurations now present in the prior art, the present invention provides an improved pool/spa filter saver system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved pool/spa filter saver system and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a pool/spa filter saver system. First provided is a cylindrical paper filter.
A rigid pipe is provided. The pipe has an interior end. The pipe has an exterior end. The pipe has a length of between 18 inches and 22 inches. The pipe has a diameter of between 0.5 inches and 1.0 inches. The pipe is adapted to function as a handle for the system during operation and use.
A pipe-to-hose connector is provided. The pipe-to-hose connector has a first end. The first end is attached to the exterior end of the pipe. The pipe-to-hose connector has a second end. The second end is rotatably coupled with respect to the exterior end of the pipe-to-hose connector. The second end is further rotatably coupled with respect to the exterior end of the pipe. The second end of the pipe-to-hose connector has female threads 26. In this manner the second end of the pipe-to-hose connector may be releasably coupled to a hose.
An adaptor/reducer is provided next. The adaptor/reducer has an interior surface. The interior surface is attached to the interior end of the pipe. The adaptor/reducer has an exterior surface. The exterior surface of the adaptor/reducer has a cylindrically shaped inner end. The exterior surface has a hexagonally shaped outer end. A radially extending abutment shoulder is provided. The abutment shoulder is formed between the inner end and the outer end of the exterior surface of the adaptor/reducer.
Further provided is a spray head. The spray head has a closed end. The closed end is in a generally hemispherical configuration. The spray head has an open end. The open end is in a cylindrical configuration. The spray head has a cylindrical intermediate region. The intermediate region is provided between the closed end and the open end. The spray head is hollow. The spray head has a common first thickness over the majority of its extent. The common first thickness is 0.01875 inches, plus or minus 10 percent. The spray head has a second thickness adjacent to the open end. The second thickness is greater than the first thickness. The interior surface of the adaptor/reducer is received upon and attached to the interior end of the pipe. The open end of the spray head is received upon and attached to the inner end of the adaptor/reducer. The open end of the spray head is provided in contact with the abutment shoulder of the adaptor/reducer.
Provided last is a plurality of micro-holes. The micro-holes are provided in the intermediate region adjacent to the open end. The micro-holes extend radially through the spray head. Each micro-hole has a diameter. The diameter is between 0.015625 inches and 0.03125 inches. The micro-holes are located in two axially spaced rings. The micro-holes are separated from each other circumferentially by between 6 degrees and 12 degrees.
The pipe and pipe-to-hose connector and adaptor/reducer and spray head are fabricated of polyvinyl chloride. The system includes cement/glue. In this manner the pipe and pipe-to-hose connector and adaptor/reducer and spray head are attached together. In this manner water introduced into the system by the hose coupled to the pipe-to-hose connector is fed through the pipe into the spray head and through the micro-holes to project a spray of cleansing water into the cylindrical filter to be cleaned.
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. 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.
