How high may drain covers protrude from the floor of a public swimming pool or water attraction?
The ANSI/ASME standard permits the cover/grate to extend to a height of two inches. The drain covers in shallow water (less than 32 inches of depth) must be installed so that the covers do not pose a tripping hazard. This may be accomplished by installing a compliant cover that does not protrude into the basin (less than ½ inch), installing a play feature to prohibit foot path over the grate or installing a grate that is flush with the floor.
