Description The device shall consist of a membrane that allows the flow of drainage to enter the plumbing drainage system. The device shall close when there is no flow. Size The device shall be sized according to the nominal pipe size of the device it installs into, except for the 3-1/2 in (DN 90)...
This Standard covers floor, area, adjustable floor, and trench drains that are used inside of, or outside and immediately adjacent to, building structures. This Standard specifies design requirements, definitions, nomenclature, outlet types and connections, grate-opening areas,...
This specification covers the material, design, structural performance, and manufacturing practice requirements for monolithic or sectional corrugated high density polyethylene (HDPE) grease interceptor tanks that are placed between commercial food service (kitchen) drains and sanitary sewer...
1.1 This specification covers high-silicon iron pipe and pipe fittings intended for corrosion-resistant service for both above- and below-grade construction. 1.2 The values stated in inch-pound units are to be regarded as standard.
