110-326 Water Heater Thermostat,Natural Gas Water Heater Valve Uni-Kit W/ 1-3/8" Shank,3-1/2" W.C,Comes with Replacement Thermocouple.

First off, do not purchase this item! It is a faulty item which will cause you an issue. The gas is not regulated properly so once it lights, flames will shoot out of your water heater. Or at least this is what happened to me and after I read the reviews so many other people. This vendor also will not allow any refunds or returns, but good news for you, if you call Amazon directly they will issue you a refund. They did not want me to make a return because it is a dangerous item, they just asked for me to dispose of it. I wish I would have read the reviews first, it would have saved me a lot of time and hassle. I also speculate that all the other gas control valves that look exactly like this but are listed by other vendors are exactly the same way, but that is my speculation. I wish I would have taken a video of the water heater when the flames ignited but I was so irate I went to the local home improvement store and bought one off their shelf. Needless to say, the hair on my arms is still growing back.

I have one of the infamous Whirlpool 'flame-lock' gas water heaters sold at Lowes in the 2006-10 era that has the 'left-hand thread' thermocouple. Lawsuits and so on were filed over these by owners.. big mess.So, flash forward, after replacing the burner + thermocouple assembly a few times over the years, come to find out that Lowes no longer carries these assemblies. I let my brother work on it this last time (b/c I rent the house to him), and he stripped out the left-hand threaded thermocouple adapter. The company that makes these adapters also stopped producing them.I needed to replace the whole gas-valve now. I found this one which conforms to the specs of the original, other than it has normal right-hand threads for the thermocouple. I installed it and it has been working fine ever since (2 months now).I'm not going to go into how to install this b/c if you don't know how to research this info yourself, then you should not be trying to do this job. It is not technically difficult, but it is dangerous for a lot of reasons not the least of which is that there's natural gas lines involved and they have to be handled correctly to avoid leaks/problems,.. problems like blowing your house up.

Now I see why this vendor does not accept returns. About 5 other sellers for this same gas valve and this is the only seller that does not accept returns. I was forced to buy from this seller because he was the only one for overnight delivery. I was desperate to get hot water for my wife and I so I went with this seller. Both 1/2 inlet and outlet on the valve are not 1/2 inch. Neither of my fittings fittings fit. I even took it my old and the new valve to Lowes to find some kind of adapter bushing fitting and they were quite baffled as well. Nothing was stripped. Maybe the threads were metric! So they say below. "Non-returnable due to hazmat safety reasons ." What a load of bunk. I guess I am out 60.00. I wonder if this seller buys the defective units and now sells them on Amazon with a no return?

My water heater has been down for the last 4 days. I have tryed to get it to work several different ways, including buying this regulator. We'll to no avail, a new regulator and thermocouple and burner assembly did not solve the problem. My pilot light would not stay lit. I put my old regulator back on the tank with the same new thermocouple and burner and it began to operate normally. I'm assuming something was wrong with this new regulator since I could not get it to work normally and the old one did begin to work for me

This product was not used because the shank is short compared to the original. I read some reviews that said the footprint has not changed much since it first came out but actually the shank is shorter by 1 1/2 inches compared to the original. To make matter worse the Amazon website said it is non-returnable due to hazmat safety reasons.

Sinceramente no creí q funcionará,,pero al conectarlo trabajo muy bien,,

Defective right out of the box, very poor quality.

The biggest problem: the outlet is neither standard, metric, British, or anything else. I visited the general hardware store, a specialty store, an even more specialized store, and finally, a fourth and NOTHING.Don't waste your money traveling all over town trying to find an adapter-buy a good one (as opposed to the Chinese feces) from the very beginning so you don't waste your time.Oh, and it's not returnable.
