The Watts ETX60 1/2" Diaphragm-Type Expansion Tank 0066607 Replaces ET60 is meant to handle extra pressure in HVAC systems caused by thermal expansion in closed-loop heating. The tank’s diaphragm is tough and keeps air and water from mixing, helping to prevent waterlogging and keep the system’s pressure steady. It is easy to add this tank to residential or light-duty systems and keep them running smoothly. It keeps pressure steady, which means the water heater and related parts will last longer, and the system will work better.
