## Customer Reviews

### ⭐⭐⭐⭐⭐ Good Replacement, Will Insulate This Time
*by D***E on September 21, 2019*

This control unit is exactly what was needed to get the hot water flowing again. Status light is white and brighter than the original. Followed Honeywell directions that said no pipe tape sealant on supply side. Compression fittings don’t need tape either. Leak checked and no problems. A small length of pipe screwed into the supply side makes for a convenient handle to remove the old unit and screw in the new one without damaging it. Quick and easy. Good deal. The failed unit was only 4 years old but I suspect the wild ambient temperature swings where it is installed caused the unit to fail. This time I will insulate it to make it last longer.

### ⭐⭐⭐⭐⭐ Satisfied
*by J***E on February 8, 2025*

But had to return

### ⭐⭐⭐⭐⭐ Winter cold showers? No!
*by K***R on January 6, 2021*

This replacement valve was exactly as expected. It arrived on time and as described. If you have some knowledge of water heaters and plumbing, it is fairly simple to install. There are multiple videos explaining installation. I would recommend replacing any plastic drain valves with a ball valve on the tank and replacing the pressure relief valve also while you have it drained. Both are pretty simple to do and will save you some potential trouble in the future. I would recommend purchase from this seller and the product is perfect. Cannot attest to the reliability of the valve as it has only been installed for a week or so. But, it is functioning perfectly now and at $129 and the time it took to put it in, it sure beats $600 for a new tank and the time it takes to put one of those in!
