2.3.3 Grates. The grates must be aligned properly and fastened by accompanying screws, unless floor sink design is for loose set installation.
2.3.4 Screws. All screws shall be made ofcorrosion resistant material.
2.3.5 Dimensions. PVC floor sink dimensions shall conform to the socket and spigot dimensions as specified in ASTM D 2665. 2.3.6 Open Area. The grates and strainers shall comply to the open area requirements of ASME A112.21.1.
3.1 Illustrations The floor sink type and sizes illustrated in Figs. 1 through 4 are commonly cast iron and Figs. 5 through 7 are commonly PVC, but other type materials may be provided. Those illustrated represent a selection for ordinary types and may be provided with a variey of tops. Top grates shall meet the requirements of ASME A112.21.1.
3.2 Floor Sinks Without Anchor Flanges Floor sinks without anchor flanges are for use where anchoring or clamping of a waterproof membrane is not required.
3.3 Floor Sinks With Anchor Flanges Floor sinks with anchor flanges are for use where anchoring or clamping of a waterproof membrane is required. The membrane is to be secured to the anchor flange with flange clamps. Provisions shall be made in the drain body for weepholes. They shall be cast in the cast iron body and drilled in the PVC body if necessary (see Figs. 5 through 7).
