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
PVC Coated Flange Model
PRODUCT DESCRIPTION
Constructed of aluminum and stainless
steel components with a large, plastisol
coated flange for hot air welding of Flex
Membrane PVC roof membranes. The drain
flange has a depressed sump area and
an oversized, low profile strainer dome to
facilitate the easy drainage of all water
from the roof surface. The Flex Retrofit
Drain PVC Coated Flange Model incorpo-
rates the technology of the RAC Backflow
Compression Seal providing a mechanical
watertight connection.
FEATURES & BENEFITS

18-in. x 18-in. aluminum drain flange
with plastisol coating. The coated
flange, provides ample area for hot
air welding of Flex Membrane PVC
membranes, giving a homogeneous
water tight connection.

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 PVC Coated Flange
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 produced no leakage.
