An improved fire department connection (FDC) having an accessible debris filter box interposed vertically in the line to permit the removal of undesired introduced solids to prevent the solids from clogging the sprinkler system which is in fluid communication with the base of the FDC. The box has a permanent filter, or removable filter media or a combination of the two types of filters, all accessible via a front removable plate thereon. The debris filter box may also be interposed vertically in other fluid flow systems that are subject to the introduction of undesired solids.

I claim: 1. A fire department connection with debris filter comprising: at least one pipe fitting; at least one upper pipe that is a pipe or a tube; a downward flow debris filter; and a lower pipe that is a pipe or a tube, wherein, said at least one pipe fitting: functions to fluidly connect to another pipe fitting on a fire hose, is located at the upper frontward portion of said fire department connection with debris filter, and is fluidly coupled to said at least one upper pipe, said at least one upper pipe is fluidly connected at one end to said at least one pipe fitting and at its other end to said downward flow debris filter, at an upper surface of said downward flow debris filter, said lower pipe is fluidly connected at its lower end to the fire protection system of the building and at its upper end to a bottom surface of said downward flow debris filter, and said downward flow debris filter is: rectangular prism-shaped on its front half and circular prism-shaped on its back half, where the diameter of the circular prism is essentially the same as the width of the rectangular prism to allow the sides of the rectangular prism to form a smooth seamless connection with the sides of the circular prism to yield a complete enclosure with a front surface, a rear surface, a set of two side surfaces, along with said upper surface and said bottom surface, wherein said smooth seamless connection reduces swirling turbulence and debris deposits in the upper portion of said downward flow debris filter, not positioned horizontally when installed, but rather the profile of said downward flow debris filter is angled at 20-70 degrees from horizontal, where the front of said downward flow debris filter is positioned below the back of said downward flow debris filter, and positioned so that fluid flows downward through said upper surface of downward flow debris filter, downward through said a downward flow debris filter, through said bottom surface of said downward flow debris filter, through said lower pipe, and on to the fire protection system of the building. 2. A fire department connection with debris filter as recited in claim 1 wherein said front surface of said downward flow debris filter is reversibly attachable to the rest of said downward flow debris filter through the use of at least one reversibly attachable fastener. 3. A fire department connection with debris filter as recited in claim 1 further comprising a circular mesh sheet segment affixed to the upper end of said lower pipe. 4. A fire department connection with debris filter as recited in claim 1 wherein the debris filter end of said at least one upper pipe extends downward into the interior of said downward flow debris filter and the upper end of said lower pipe extends upwards into the interior of said downward flow debris filter, such that there exists a gap between said members appropriately sized to accepted by sliding and holding into place, sliding to remove for cleaning, and sliding back into place, in repeated fashion, a removable mesh sheet. 5. A fire department connection with debris filter as recited in claim 4, wherein the extension of said at least one upper pipe located in the interior of said debris filter has an arched cutaway section (67) on its front surface to provide hand-access to said circular mesh sheet or said removable mesh sheet or both. 6. A fire department connection with debris filter as recited in claim 4, wherein said removable mesh sheet has mesh holes sized at 1/16-⅜ of an inch.
