## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked as expected.
*by Z***I on April 21, 2025*

Installed easily and worked as expected.

### ⭐⭐⭐⭐⭐ Works and easy to install
*by C***S on February 26, 2025*

Replaces relief valve on hot water heater and this is the second one since original installation. No problem with quality (once sold this brand) so partial to it, but condition of water shortens life of valve, so just a necessary maintenance procedure.

### ⭐⭐⭐⭐⭐ Check part numbers for an exact fit.
*by N***E on January 3, 2025*

The T&P Valve on our hot water heater was leaking. It was part number SL100XL-3M7. This one has a shorter neck than ours. I bought it for the emergency and it fit OK but rubbed up against the plastic trim on the hot water heater but still works perfectly. This product works perfectly as intended so I'm giving it 5 stars. I need to find an purchase the correct T&P Valve as this one is too short for our tank.
