As with all building materials, it is the responsibility of the installer to review its usage with a design professional to
confirm safety, compatibility and acceptance with the Flex Membrane roof system as well as local building codes.
Flex Retrofit Drain
Clamping Ring Model
PRODUCT DESCRIPTION
The Flex Retrofit Drain Clamping Ring Model
is constructed of aluminum and stainless
steel for durability and designed for use
with single ply, BUR and modified bitumen
roofing systems. The drain features an extra
large flange for positive attachment of the
roof flashing membrane, a recessed metal
clamping ring for roof termination and proper
drainage, along with an oversized drain
strainer to minimize damming. The RAC
Backflow Compression Seal is compatible
with PVC or cast iron leader pipes and is
available in 3-in., 4-in., 5-in. and 6-in. sizes.
FEATURES & BENEFITS
•
Drain flange insures consistent, stable
attachment to the substrate outside
of the existing drain bowl and positive
attachment of flashing membrane.
• Strainer dome features a low profile
base to promote drainage and the large
diameter provides added flow capacity
and minimizes damming.
• 9-in. long drain stem accommodates most
existing field conditions with custom
drain pipe lengths available for quick turn
elbows or deep existing drain bowls.
• The aluminum clamping ring is recessed
into the drain flange to maximize drainage
and is secured to stainless steel studs.
• The RAC Backflow Compression Seal is
quickly activated at drain flange level and
protects the roofing system and building
contents from water backup damage.
• Saves time and money by allowing easy
installation from the rooftop without
disturbing occupants.
APPlICATION
Flex Retrofit Drains are designed to replace
existing drains in reroofing applications.
Installed from the roof surface, Flex Retrofit
Drains are engineered to be installed with-
out removing the existing plumbing or fixture
while providing a watertight connection to
the roof system and the existing plumbing.
APPROvAlS & STANDARDS
ANSI/SPRI RD-1 is a national performance
standard for retrofit roof drains. While most
retrofit drains are not tested to this standard,
the Flex Retrofit Drain Clamping Ring Model
with RAC Backflow Compression Seal
exceeds the standard, which requires that
the seal hold a 10-ft. column of water for 24
hours without leaking.
IAPMO PS 97-96 – a standard plumbing
industry test designed to check for leakage
at connections under a 10 foot head of
water for a 24 hour period. This test was
performed by the Smith-Emery Company,
a nationally recognized independent test
laboratory providing physical testing
of construction related materials. The
Flex Retrofit Drain Clamping Ring Model
produced no leakage.
