Internal Recirculation System

Viega

The SmartLoop™ system helps maintain water quality by reducing water stagnation. It uses a supply riser to insulate the internal recirculation-line tubing and keeps water hotter longer. Water within the system remains in motion, which reduces the risk of waterborne pathogens, including legionella. The system requires no separate return pipe, and it uses less insulation and fewer fittings, supports, penetrations, and core drilling than conventional recirculation installations.
