Abstract: A masonry wall protection device includes a first member, a second member and a tensioning belt. The second member includes a vertical second leg that defines an outer edge that includes a position slot, and a horizontal second leg. The first member includes a vertical first leg, and a horizontal first leg that has a top edge that defines a plurality of position slots and further defines a bore that is sized and shaped for sliding receipt of the horizontal second leg. The horizontal second leg is slidingly positioned through the bore so that the distance between the vertical first and second legs can be adjusted to approximately equal the width of the top of the masonry wall. The tensioning belt is positioned between the first and second members fully stretched such that the vertical legs are firmly positioned a selected distance apart.

Abstract: An embodiment includes a drain pipe waste water closure protection device which allows passage of fluids through a drain into a pipe waste water closure and a waste water pipe while preventing backflow of fluid or gas from the waste water pipe and pipe waste water closure, as well as preventing evaporation of a water-containing pipe waste water closure located below the drain pipe waste water closure protection device in the waste water pipe. Embodiment drain pipe waste water closure protection devices are easily installed in existing or new drains. Embodiments have two radial disc seals which insure a strong seal between the drain pipe waste water closure protection device and the drain wall. Embodiments include a reinforcing band embedded below the radial disc seals which prevents failure of the radial disc seals. Embodiments include a quadruple pressure accumulating seal which protects against the flow of gas or fluid from the waste water pipe.
