Referring to FIG. 1, a method is provided for plugging toilet flange fitting 12. Toilet flange fitting 12 consists of a bore 36, through which leads to a regular toilet drainage system (not shown). Bore 36 consists of interior walls 38. A toilet (not shown) is initially installed overtop of toilet flange fitting 12. The toilet is removed, and insertion end 26 of plug 10 is inserted into bore 36 of toilet flange fitting 12 in the orientation indicated by dotted lines 40.
Circumferential seals 16 seal up against interior walls 38 of bore 36, preventing gases or liquids from passing through bore 36 in either direction. Attachment flange 18 of plug 10 is then attached to toilet flange fitting 12 in the same manner that the toilet was secured to toilet flange fitting 12. This way plug 10 can be used to seal bore 36 of toilet flange fitting 12 when an installed toilet is subsequently removed. Plug 10 is designed using A.B.S.
plastic, and is meant as a permanent or temporary seal for toilet flange fitting 12. Plug 10 can seal toilet flange fitting 12 for short or long periods of time, preventing sewer gases and fluids from passing into the room where toilet flange fitting 12 is located. Sealing toilet flange fitting 12 is advantageous while performing maintenance work on the toilet, or while removing the toilet from toilet flange fitting 12 until further notice.
Referring to FIG. 3, another embodiment of a method of plugging toilet flange fitting 12 is provided. A toilet (not shown) is initially installed overtop of toilet flange fitting 12. The toilet is removed, and insertion end 126 of plug 110 is inserted into bore 36 of toilet flange fitting 12 in the orientation indicated by dotted lines 40. Plug 110 can be inserted into bore 36.
Circumferential seals 116 seal up against interior walls 38 of bore 36, preventing gases or liquids from passing through bore 36 in either direction. Plug 110 is not secured to toilet flange fitting 12 with bolts, as was previously described for plug 10. Plug 110 is pushed into toilet flange fitting 12 and held in place by the friction provided by circumferential seals engaging interior walls 38. This way plug 110 can be used to seal bore 36 of toilet flange fitting 12 when an installed toilet is subsequently removed. Plug 110 can be easily removed from sealing contact with toilet flange fitting 12 using handle 122. Plug 110 is designed using regular plastic, and is meant as a temporary seal for toilet flange fitting 12. Plug 110 can seal toilet flange fitting 12 for short periods of time, preventing sewer gases and fluids from passing into the room where toilet flange fitting 12 is located. Sealing toilet flange fitting 12 is advantageous while performing maintenance work on the toilet. Both of plugs 10 and 110 can be re-used.
