I tried this Camco valve 10471/10473 3/4" temp and pressure relief valve with 4" epoxy probe, but it does not seal from the beginning. That's why I chose this one. No problem to report here. It sealed after 1-2 attempts by actuating the test lever. FYI, it says "Rome" here, but it's not. This is actually WATTS 100XL (listed on the valve ID label) in a box marked PROTECH. The back of the box says it's distributed by Rheem so it's most likely an OEM replacement.
