A disposable plug for installation in a cylindrical water line to temporarily block the water line to the passage of water therethrough. The disposable plug includes a cylindrically shaped tablet having a diameter substantially equal to the diameter of the water line so that when installed within the water line, water is prevented from passing the disposable plug. The cylindrically shaped tablet is characterized as being at least partially dissolvable when contacted with water. A water impermeable membrane surrounds at least a portion of the cylindrically shaped tablet to selectively prevent water from contacting it as long as the disposable plug acts to temporarily block the water line. The water impermeable membrane can be selectively disrupted allowing water to contact the cylindrically shaped tablet to selectively remove the disposable plug when no longer needed.
