The leak containment assembly contains a leak collector for installation between the toilet base and the support flooring for preventing the water leaks onto the support flooring during flushing. The leak collector contains an attachment flange for attaching the leak collector to the support flooring, a collector pan for collecting water leaks during flushing, and an outlet pipe in fluid communication with the collector pan for channeling the leaks into the plumbing drain pipe. It also contains a leak seal assembly for installation and sealing between the toilet base and the leak collector. The leak seal assembly contains a flow channel for channeling water flow into the outlet pipe of the leak collector, and a seal for sealing between the toilet base and the leak collector. ## Claims ### Claim 1 A toilet leak containment assembly for preventing water leaks from a toilet during flushing on to the support flooring to which the toilet is attached, the toilet including a toilet base having an interior toilet passage through which water flows into a plumbing drain pipe during flushing; said assembly comprising: a leak collector for installation between the toilet base and the support flooring for preventing the water leaks into the support flooring during flushing; an attachment flange for attaching said leak collector to the support flooring; a collector pan included in said leak collector for collecting the water leaks during toilet flushing; an outlet pipe in fluid communication with said collector pan for channeling the leaks into the plumbing drain pipe; a leak seal assembly for installation and sealing between the toilet base and said leak collector; a flow channel included in said leak seal assembly for channeling water flow into said outlet pipe of said leak collector; and a seal surrounding said flow channel for sealing between the toilet base and said leak collector. ### Claim 2 (depends on 1) The assembly of claim 1 wherein said attachment flange contains flange openings for attaching said leak collector to the support flooring. ### Claim 3 (depends on 1) The assembly of claim 1 wherein said collector pan contains mounting elements for mounting the toilet to said leak collector. ### Claim 4 (depends on 3) The assembly of claim 3 wherein said mounting elements are located on the floor of said collector pan. ### Claim 5 (depends on 3) The assembly of claim 3 wherein said mounting elements are openings that do not extend through the floor of the collector pan; whereby any water leakage that enters the openings cannot leak into the support flooring. ### Claim 6 (depends on 1) The assembly of claim 1 wherein said seal surrounding said annular flow channel is a wax seal. ### Claim 7 (depends on 1) The assembly of claim 1 wherein said flow channel included in said leak seal assembly includes an annular flange surrounding said flow channel. ### Claim 8 (depends on 7) The assembly of claim 7 wherein said annular flange overlies at least a portion of said seal surrounding said annular flow channel. ### Claim 9 (depends on 7) The assembly of claim 7 wherein said flow channel is tapered away from said outlet pipe to provide a space for leakage to flow should leakage flow over said annular flange and said seal has deteriorated to allow for water flow into the collector pan and into the outlet pipe. ### Claim 10 A leak seal assembly for preventing water leaks from a toilet during flushing on to the support flooring to which the toilet is attached, the toilet including a toilet base mounted to the support flooring having an interior toilet passage through which water flows into a plumbing drain pipe during flushing; said assembly comprising: an annular flow channel for location between the toilet base and the drain pipe to channel water flow into the plumbing drain pipe; an annular flange surrounding said flow channel, said annular flange includes an annular flat surface extending to an inclined annular surface for directing water into said flow channel, whereby, water leaks are directed into the annular flow channel for channeling water flow into the plumbing drain pipe; a seal surrounding said annular flow channel for sealing between the toilet base and the plumbing drain pipe; and said annular flange overlying at least a portion of said seal. ### Claim 11 (depends on 10) The assembly of claim 10 wherein said seal surrounding said annular flow channel is a wax seal. ### Claim 12 (depends on 10) The assembly of claim 10 wherein said flow channel is tapered away from the drain pipe to provide a space for leakage to flow should the leakage flow over said inclined annular surface. ### Claim 13 A leak collector for installation between a toilet base and sub flooring for preventing water leaks from a toilet to contact the sub flooring to which the toilet is attached, the toilet including a toilet base having an interior toilet passage through which water flows into a plumbing drain pipe during flushing; and a seal disposed between the toilet and said collector, said leak collector comprising: an attachment flange having means for attaching said leak collector to the sub flooring; a collector pan included in said leak collector, disposed below said attachment flange, having a collection surface above a bottom surface of said sub flooring, for collecting the leaks during toilet flushing, wherein the seal is disposed between the toilet base and collector pan when installed, and an outlet pipe connected to said collector pan for delivering said water leaks collected in said collection pan into the plumbing drain pipe. ### Claim 14 (depends on 13) The leak collector of claim 13 wherein said attachment flange contains flange openings for attaching said leak collector to the sub flooring. ### Claim 15 (depends on 13) The leak collector of claim 13 wherein said collector pan contains mounting elements for mounting the toilet to said leak collector. ### Claim 16 (depends on 13) The leak collector of claim 13 further comprising a second outlet pipe horizontally spaced from said first outlet pipe connected to said collector pan for delivering said water leaks collected in said collector pan into the plumbing drain pipe. ### Claim 17 (depends on 13) The leak collector of claim 13 wherein mounting elements are located on the floor of said collector pan. ### Claim 18 (depends on 17) The leak collector of claim 17 wherein said mounting elements are openings that do not extend through the floor of the collector pan; whereby any water leakage that enters the openings cannot leak into the support flooring.
