DESIGN

The design depends on the function of the gully, for example, floor wash-down, direct discharge from equipment, rodding point, or associated use with drainage channels.

When deciding upon the specification of gully, simply make the four choices detailed below.

Gully Body Gully type – dependant upon capacity, flow rates are shown in the table below, (however, basket size can become the overriding factor when selecting a gully, or, head of water when considering deluge drainage). Outlet direction – side or vertical. Outlet diameter – All outlet spigots are compatible to uPVC pipes sizes to BS 4660, IE, 82, 110, 160. Standard couplings and adapters are therefore readily available within the industry to connect to clay and cast iron drainage. Grating Seating The edge profile will depend on the floor finish, for example, tile, resin or vinyl. See grating seatings. A seating is not required when using a trapped gully with a channel. Grating Gratings should be selected for their wash down requirements, free drainage area and loading capacities. (See 4000 series gratings). Material Grade See stainless steel information
