Review on 🌊 General Wire Flood Guard Float Model, Small 4-Inch, Plated - Enhanced for SEO by Monica Young

This protective cover will not fit 4" ID ceramic floor drains. The guard is only 3 and 3/4 OD and can be extended an additional 1/8" by tightening the screws. This will still leave it loose in the drain pipe. To get this to work I had to wrap 7 feet of 1" wide duct tape around the rubber ring to fit snugly in the drain pipe and then by tightening 4 bolts I was able to extend that extra 1/8". and create a strong hermetic seal. other reviews mention the use of black tape for this purpose. Too bad its size isn't better and isn't designed to expand more than 1/8 inch. I have used other hard blue plastic versions of the same device in the past which fit and worked without modification.
