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 drinking water supply/ overhead fire sprinkler system. Note that FNPT or Flanged connections require separate adapter. The TR2 features Lead Free* Pipe construction to comply with Lead Free* installation requirements.

Watts Transition Risers are precision engineered and manufactured 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 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.
