Abstract
Abstract A cylindrical sight glass housing is threaded to the end of the horizontal septic tank inlet pipe within a building basement which pipe extends through a vertical basement wall and terminates within an in-ground septic tank. A port within the cylindrical housing permits water under pressure to impinge against the glass window to clean the window and flush inlet pipe to the septic tank. A thin tube air conduit projects through the cylindrical housing and has attached thereto a coiled flexible plastic pipe which terminates in a porous aeration element. A conical piston is fixed to the aeration element and a vibrating air pump supplies air to the coiled flexible pipe and aeration element. The flow of sewage through the inlet pipe or the water under pressure in cleaning the sight glass drives the piston through the length of the pipe and into the septic tank where the air escaping from the porous aeration element provides aerobic action to the sewage within the tank and to the leach field downstream thereof.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
263 words
A COMBINED END PLUG FOR A BUILDING SEPTIC TANK INLET PIPE AND TANK AERATOR COMPRISES: A CYLINDRICAL END PLUG HOUSING FOR SEALED ATTACHMENT TO THE BUILDING END OF A HORIZONTAL SEPTIC TANK INLET PIPE LEADING FROM A BUILDING BASEMENT TO THE UPPER END OF AN UNDERGROUND SEPTIC TANK EXTERIOR OF THE BUILDING AND SPACED THEREFROM, A PORT OPENING UP INTO THE INTERIOR OF THE CYLINDRICAL END PLUG HOUSING AT AN ANGLE TO THE LONGITUDINAL CENTER PLANE PASSING THROUGH THE HOUSING AND THE PORT OPENING TO EFFECT A VORTEX CLEANSING ACTION WHEN LIQUID UNDER PRESSURE ENTERS THE PORT AND IMPINGES AGAINST THE INTERIOR OF THE END PLUG HOUSING, THE IMPROVEMENT COMPRISING: A SMALL DIAMETER AIR TUBE PROJECTING THROUGH SAID CYLINDRICAL HOUSING, A COILABLE, FLEXIBLE HOSE OF A LENGTH IN EXCESS OF SAID INLET PIPE FLUID COUPLED TO THE END OF THE AIR TUBE INTERIOR OF THE PLUG AND TERMINATING IN AN AERATION MEMBER, AND PISTON MEANS OPERABLY COUPLED TO SAID AERATION MEMBER AND SPANNING THE INTERIOR OF SAID INLET PIPE AT THE TIME OF INITIAL INSTALLATION OF SAID END PLUG TO SAID SEPTIC TANK INLET PIPE; WHEREBY, LIQUID UNDER PRESSURE PASSING THROUGH SAID INLET PIPE UPSTREAM OF SAID PISTON CAUSES SAID PISTON, SAID AERATION MEMBER AND SAID COILED FLEXIBLE HOSE TO MOVE AXIALLY THROUGH SAID INLET PIPE TO EXTENT THAT SAID AERATION MEMBER AND A PORTION OF SAID FLEXIBLE HOSE FALLS BY GRAVITY INTO SAID SEPTIC TANK, WHEREBY, SUBSEQUENT APPLICATION OF AIR UNDER PRESSURE TO THE END OF SAID AIR TUBE PROJECTING EXTERIORLY OF SAID CYLINDRICAL HOUSING, PERMITS AERATION OF THE SEPTIC TANK CONTENT.
