Sizes: 2" (50mm)
The Model 007M1DCDA Double Check Detector Assembly is
specifically designed to protect against possible backpressure
and backsiphonage conditions for non-health hazard (i.e., pol-
lutant) application in accordance with Local Governing Water
Utility Code. This assembly is primarily used on commercial
fire sprinkler systems where Local Governing Code mandates
protection from non-potable quality water being pumped or
siphoned back into the potable water system.

Product Specifications
The Model 007M1DCDA consists of a main line valve body
composed of two (2) independently acting approved poppet-
type check modules with replaceable seats and disc rubbers.
Servicing of both check modules do not require any special tools
and are accessed via a single top entry cover. This device is fit-
ted with approved UL Listed OS&Y Gate Valve Assemblies and
contains properly located resilient seated test cocks along the
main valve body.
The auxiliary bypass line contains a

8
"x 3 ⁄
4
" (16 x 19mm) Water
Meter that complies with ANSI/AWWA Standard C700 coupled
with an approved double check assembly (DC). The bypass line
is design to detect leaks or unauthorized water usage of the
water system while protecting against possible backpressure
and backsiphonage conditions for non-health hazard (i.e., pollut-
ant) application.
