Finding the right part
Identify your cylinder from its data plate and check whether it is direct or indirect, as elements and thermostats differ between the two. Relief valves must match your cylinder's pressure and temperature rating, and on unvented cylinders they should be fitted by a G3-qualified installer. Our guide on how to identify the right water heater spare part can help, or use the parts finder or our Can't Identify Your Spare Part? service.
