ABSTRACT:
The present invention pertains to a temporary stopper for the outlets of toilet bowls. In particular, this stopper is adapted for installation into and removal from the open top of a toilet bowl and when installed is adapted to stop any and all back flow from a connected sewer. Back flow often occurs when a sewer in addition to its normal discharge is also subject to a flow of water such as may be present after a heavy rain. This may be an infrequent occurrence but does occur in toilet bowls in basements and/or first floor installations. Back flow can and does cause damage and odor proliferation in such installations. A temporary plug that is readily and easily installed to halt such back flow prevents damage and afterward cleanup. The need for such a plug is usually for only a short period of time such as 6 or 12 hours although the time period is not a factor in its use.
