Reliance Hot Water Heater Gas Control Valve 100112336 1" Cavity Thermostat Compatible with Reliance, State, A.O. Smith, and American branded heaters

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.

These Honeywell electronic gas control valves are designed to prevent serious malfunctions from causing major damages or fires, but the problem is when they detect a fault they may never work again. There are some hacks out there that may get the valve to working again but usually they are futile. Amazon's pricing for this gas control valve is good, considering free, fast Prime delivery. Beware, there are similar looking Honeywell valves on the market, some of which cost less, so make sure you are getting the correct part number for your hot water heater. The valve is relatively simple to change with minimal tools. Make sure you turn off and fully drain the hot water heater first. Since gas lines are involved you may want to hire a licensed plumber to install the valve, unless you are confident in your abilities,

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!

It worked pretty quickly with my unit but would have appreciated someone getting back in touch with me prior to ordering.

Hot water heater went out. Did some Youtubing, found the problem, ordered this unit and replaced it in about 30 minutes. Fit great, worked great and saved a ton of money on labor costs if I had to hire a plumber to take care of the problem.

Works ok

lasted 3 1/2 years. will not longer feed gas to the pilot light when attempting to relight.

The gas control valve on my 9 year old AO Smith hot water heater went out with the 5 blinks of death. The nice thing was it was still producing enough hot water for 1 minimally acceptable shower since it took a few weeks to get fixed. My plumber recommended full replacement but when I saw the price of the part I decided to risk a repair. I read online that AO Smith tanks can last 20+ years. If this tank lasts 3 more years I will have broke even compared to replacement including labor. I am glad I hired a plumber as my tank would not drain until they removed the pop off valve plus I don't like to mess with gas. The valve was the perfect fit for my tank. I provided the vendor with my tank's serial number and they told me the exact part to order.
