Exact replacement for RV Water Heater

Original valve worked after 4 years no more. I manually open it when draining the water heater so it acts as a vent and allows for quick draining. Last time I drained it, no more ventilation; the water flowed out slowly. Removing the original required removing the firebox cover and required some penetrating oil, care and patience to remove the valve. The new one is exactly the same with thread sealant already applied. Works well.

Pros
  • Maximum Temperature Setting (degrees F): 210 Maximum Pressure Setting (psi): 150 CSA Capacity (BTU/hr): 105,000 Inlet Thread Size - NPT (inches): 3/4
Cons
  • Expensive

This is actually a WATTS 100XL, still working

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.

Pros
  • Kits with this part: 45W613
Cons
  • Available in white only

Works great with easy DIY installation.

I have sold my house and the buyers rightly wanted to see the house. The examiner decided to pull the lever on the pressure relief valve, which worked fine even though the sump under the pressure relief line was completely dry. It started dripping immediately, albeit slowly. I ordered a new relief valve and when it arrived I set the temperature control on the water heater to the "vacation" position, closed the cold water inlet valve and drained about 6 gallons from the water heater. After…

Pros
  • Output Thread Size - NPT (inches): 3/4 Overall Length (inches): 7-1/4 Body Length (inches): 3-1/4 Sensor Length (inches): 4
Cons
  • Questionable purchase for the elderly
