Josam offers a complete line of roof drains which include Large Sump, Medium Sump, Small Sump, Sill Type, Promenade Top, Parapet Type, Flow Control Type, Overflow Type, Green Roof Drains, and miscellaneous roof drains and accessories and PVC body.

LEVELEZE® Roof Drains are just what the name implies - easy to level to the proper elevation. The adjustable integral top is mated to the body and support ring with a heavy machined thread which permits virtually unlimited top-level adjustment to accommodate various insulation thicknesses. The line contact between the threads provides positive circumferential support of the top at any adjusted elevation. This versatile drain readily adapts to changes in finished roof elevation. With LEVELEZE® on the job, installation delays normally encountered, where fixed height extensions are specified, will not be experienced.

WEJLOC® CLAMP RING - GRAVEL STOP Embodies the exclusive compression wedge lock principle to secure flashing with a positive non-puncturing bond to mating flange of collar. The gravel stop prevents roof surface aggregates from being washed into drain while permitting total drainage through "V" notch weirs.

ADJUSTABLE COLLAR - The LEVELEZE® machined thread permits raising or lowering of roof flange to meet the insulation thickness at the required elevation, even after leader is connected to drain and the roofing is applied.

SUPPORT RING & GASKET - Cast iron support ring mates with LEVELEZE® adjustable collar permitting smooth uninterrupted adjustment to accommodate various insulation thicknesses. Gasket prevents leakage between drain body and support ring.

The roof drainage system is designed to receive rainwater as it falls on the roof and convey it to the street, sewer facilities or other means available for its disposal. This system should be sized to handle the maximum rainfall used as design criteria for a project. Roofs are of various shapes and dimensions, with sections which may be more or less than the 10,000 sq. ft. recommendation for each drain. Therefore, sometimes it will be necessary to depart from this recommendation as required for proper placement and uniform distribution of roof drains. There are many variations and options available for roof drains and its components. These variations must be specified and installed when the type of roof construction dictates their use.
