Questions & Answers

XE40M06ST45U1 Will it work with this model
ByAug 5, 2026
1 Answer | 
Answer This Question

This should fit your water heater but we would recommend checking with Rheem to verify what parts should be used.

    Is this compatable with WATTS LL100xl-2M7?
    ByJul 30, 2026
    1 Answer | 
    Answer This Question

    This is similar to that valve but has a shorter shank than the Watts valve and may not work on your water heater, depending on the thickness of the insulation.

      Is this comparable with ENT 50-130. 2" SHANK. Overall length 5 1/4".
      ByJul 22, 2026
      1 Answer | 
      Answer This Question

      Yes, the NCLX-5LX is comparable provided the ratings match the original valve 210 F, 150 psi, and equal or greater BTU relieving capacity. The 2-1/2" shank is generally acceptable as a replacement, but you should verify there is adequate clearance for installation.

        Is this compatible with Rheem XE50T06ST45U1
        ByJul 19, 2026
        1 Answer | 
        Answer This Question

        No, this does not appear as though it will work as a replacement for that water heater. We would recommend speaking with Rheem for what valves are compatible.

          Is this compatible with a Rheem Model XG40T06EC36U1 water heater?
          ByApr 30, 2026
          1 Answer | 
          Answer This Question

          The NCLX series should be compatiable with this Rheem model. The valve meets the standard residential water heater requirements.

            Hello Ronnie, We would recommend speaking with Rheem regarding which relief valve is needed for your water heater.

              I’m looking for something compatible with 100 XL
              ByMar 21, 2026
              1 Answer | 
              Answer This Question

              The Cash Acme NCLX-5 or NCLX-8 would be an equivalent to the Watts 100XL depending on the thermal element and shank length.

                ByMar 19, 2026

                Answer This Question

                Yes, it is generally compatible, but it is not “universal” without checking shank length.

                  It was a perfect replacement for the NCLX-5S that was in my 20 gallon State Water Heater. No more leaks!

                  The Cash Acme P/T valve was easy to install into my existing hot water heater after the old one failed. It fit perfectly as it was the identical valve that I removed. So far the new P/T valve has been working flawlessly for about 5 weeks. It meets my expectations and I would recommend it to my friends.

                  Fixed my Rheem hot water heater myself! It has been pushing out about a gallon every few days. Even after shutting off the inlet valve and draining off several gallons of water and having the closest hotwater faucet open, it continued to gurgle and push water out while trying to remove this valve. So I just took a pic of it while I had it out quickly and went and bought one. Fixed the issue though.

                  Easy to install but watch out for the shank length!
                  I installed this Temperature&Pressure relief valve to replace a defective TP valve in our GE SmartWater heater (installed in Jan 2006). The old TP valve leaked when the water temperature was set near the "white" (optimal temperature) mark. I initially bought the 1-1/4" shank version but after removing the old TP valve, realized that our heater uses the 2-1/2" shank. So that's something to watch out for - you won't know the shank length you need until you remove the old valve. Oh and be sure to set the water temp all the way down to 'vacation mode' or lower and also close the cold water inlet valve before you drain the water from the tank to just below the valve level. You will also need to leave a couple hot water faucets open in the house. Use teflon tape on the valve threads before tightening the TP valve - don't use a lot of torque, it should fit just snug before you attach the downspout tube.

                  Broken drain line
                  Had to replace relief valve because the pvc screwed in broke and could not be replaced. Meet my need to avoid this from happening again.
