Series TR
Transition Risers
Sizes: 4" – 10" (100-250mm)
Series TR Transition Risers are used to connect the main fire
supply to the building overhead fire system. The fitting passes
under the foundation without joints and extends up through the
floor. Provided with installation tabs, the unit has a CIPS (Cast
Iron Pipe Size) coupler for easy connection to the underground
supply (AWWA C900 PVC and Ductile Iron Pipe) and industry
standard grooved-end connection (AWWA C606) on the building
side for easy connection to the overhead fire sprinkler system.
Watts Transition Risers are precision engineered and manu-
factured to provide exceptional reliability and reduce instal-
lation time & labor costs associated with field assembly. In
accordance with NFPA 24-2007, the UL and FM approved
Transition Risers replace numerous fittings, elbows & spools
and reduces the possibility of leaks or failure in comparison 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.
