Series TR2
Transition Risers
Customizable
Sizes: 2" – 3"
Series TR2 Transition Risers are used to connect the main
potable water supply to the building drinking water system or fire
supply to the building overhead fire system. The fitting passes
under the foundation without joints and extends up through the
floor. Provided with either an MNPT or FNPT (ASME B1.20.1),
Flanged [ANSI B16.5 150], or industry standard grooved-end
connection (AWWA C606) for easy connection to either the
underground supply (PVC, Ductile Iron, or Copper Pipe) or drink-
ing water supply/ overhead fire sprinkler system. Note that FNPT
or Flanged connections require separate adapter. The TR2 fea-
tures Lead Free* Pipe construction to comply with Lead Free*
installation requirements.
Watts Transition Risers are precision engineered and manufac-
tured to provide exceptional reliability and reduce installation
time & labor costs associated with field assembly. In accordance
with NFPA 24 and numerous regional plumbing codes, the UL/
FM approved Transition Risers replace numerous fittings, elbows
& spools and reduces the possibility of leaks or failure in com-
parison to traditional installation methods and materials. Factory
tested integrity ensures the highest quality installation. The use of
stainless steel significantly increases the reliability and life of the
riser.
