Abstract:
A disposable plug for installation in a cylindrical water line to temporarily block the water line to the passage of water therethrough, said disposable plug comprising a cylindrically shaped tablet having a diameter substantially equal to the diameter of the water line so that when installed within said water line, water is prevented from passing said disposable plug, said cylindrically shaped tablet being characterized as being at least partially dissolvable when contacted with water; a water impermeable membrane surrounding at least a portion of said cylindrically shaped tablet to selectively prevent water from contacting said cylindrically shaped tablet as long as said disposable plug acts to temporarily block said water line; and means for disrupting said water impermeable membrane a sufficient amount to allow water to contact said cylindrically shaped tablet when said water line is not intended to be so blocked.
