3 FLOOR SINK TYPES AND SIZES
3.1 Illustrations
The floor sink type and sizes illustrated in Figs. lthrough 4 are commonly cast iron and Figs. 5 through7 are commonly PC，but other type materials maybe provided.Those illustrated represent a selection forordinary types and may be provided with a variey oftops. Top grates shall meet the requirements of ASME4112.21.1.
3.2 Floor Sinks Without Anchor FlangesFloor sinks without anchor flanges are for use whereanchoring or clamping of a waterproof membrane isnot required.
3.3 Floor Sinks With Anchor Flanges
Floor sinks with anchor flanges are for use whereanchoring or clamping of a waterproof membrane isrequired. The membrane is to be secured to the anchorflange with fange clamps. Provisions shall be madein the drain body for weepholes. They shall be castin the cast iron body and drilled in the pyC body ifnecessary (see Figs. 5 through 7).
