JR Smith 148 Roof Drain & Overflow Features... 

JR Smith 148 roof drain & overflow, is comprised of the primary and overflow roof drains combined into one convenient and easy to install unit. Both of the roof drains have bottom outlets in 2′ – 4″ pipe sizes. The part numbers are 148-Y02, 148Y03 and 148Y04.

 Each of the cast iron roof drain bowls are 8-1/2″ in diameter and include a protective gravel stop/membrane clamp (flashing ring), the purpose of which is to compress the membrane and make a water tight seal and help to prevent gravel from entering the roof drain.

Also included are two domes or leaf grates as they are also referred to. These prevent debris from entering the roof drains. Both of the roof drains have a corrosion resistant Duco coating to help guard against rust and corrosion. 

JR Smith 148 Roof Drain Installation Video

The purpose of this video is to show how using roof drain sump pans can prevent standing rainwater on a flat roof and the resulting extensive roof damage that often occurs.

The video illustrates how a roof drain sump pan can accomplish this by lowering the roof drains. The exact steps taken are not shown. What is shown is the condition of the roof and it’s condition after the completion of the work.  This clearly shows the positive effect that roof drain sump pans can have on a flat roof.

Going forward, new tech videos will be released that will clearly show the installation process. As such, be sure to like, subscribe and click the little bell icon and you will be automatically notified.
