We got a new thermocoupler kit for our hot water heater, replaced the old one and it's still not working

Don't see why not give it a go nothing to lose

Double vent...??

It really won't make any difference.

Your thermo-couple is your trouble.

Every hardware store.... has them (spare: BUY 2).

Take your old one out... for (length) sizing purposes.

They uswually PULL out of the pilot end...

DO NOT OVER-TIGHTEN when re-installing!!!

Replace thermocouple is best start point.
Example Whirlpool manual shows general replacement steps on page 22:
Buy thermocouple at hardware or home center. measure length before going to store.

Utube videos show how to replace thermocouple

Many things can affect pilot:
Low gas pressure, Water or air or debris in the gas control valve, High-heat event causing ECO to trip requiring new gas control valve, burner and tubes needing clean-out, FV sensor tripped, loose or bad thermocouple.
Manual above shows general steps for doing some of these things, but service technician is probably best choice if thermocouple does not fix problem.

Gas water heaters require periodic maintenance.
If repairs cost more than $330, then buy new gas water heater and install yourself.
Use the old one for a solar collector.

Hopefully just the thermocouple. The thermocouple is the small rod right next to the pilot light. The flame on the pilot heats up the thermocouple and keeps the gas valve on. You can replace it yourself. The thermocouple will be connect by a small nut on the underneath side of the valve, and you will have to pull the thermocouple out of the pilot assembly. Not an expensive part, you can get it at any hardware store. Hope this helps you .

In simplest terms, a thermocouple is a temperature sensor. Normally inexpensive, a thermocouple is standard on hot water tanks. If your thermocouple breaks or you feel it is not working properly, consider replacing it rather than installing a new gas hot water heater.

Begin this project by shutting off the gas control knob on your hot water heater. Once you are sure that the gas is off, you should use a wrench to remove the nut that attaches the thermocouple to the gas hot water tank. This nut should appear to be securing a piece of copper tubing or other type of tubing. With the nut removed, you should also pull down on the tubing, dislodging it from the thermocouple.

Sometimes there is another nut that attaches the end of the thermocouple to the pilot bracket, if this is the case you should unscrew this nut as well. You can slide it down the tubing and keep it there until you need to replace it.

With the nuts that were holding the unit in place removed, you should be able to slide the old thermocouple out of the brackets that hold it to the hot water heater. You should then take it to a hardware or home improvement store and find a suitable replacement. Then follow these steps to install the new part and fix the hot water heater.

To change the thermocouple, you should press the end of the thermocouple into the pilot bracket as far as you can. If you had to remove a second nut to remove the old thermocouple, now is the time to replace that nut securely.

With the thermocouple in place, you should connect the lead to the control unit. Use the nut you removed in the beginning steps to secure the lead. You should then tighten it at least a quarter turn with a wench to make sure the lead is securely attached to the control unit of the gas hot water heater.

Now that the new thermocouple is installed on your gas hot water heater, turn on the gas shut off valve that you turned off earlier. You should be able to relight the pilot and the functionality of your gas hot water heater should be restored.

Yes you can light it with a BBQ type lighter (long enough).
If it lights and stays lit then you need to change the thermocouple (looks like a little pipe off gas valve)

Typically, if you have replaced the thermocoupling and are still experiencing problems, it means the master control valve is bad. It also may be a venting problem, which I would not rule out. If you call the manufacturer with model and serial number, they will be able to help you better diagnose your problem.

hello!! if you changed the thermocouple & the pilot still goes out !! could be a thermostat ( the electromagnet pilot safety ) goes bad !! make sure pilot is clean & should be sharp BLUE pilot !! not yellow & soft !! also hold down the button light the pilot use a digital volt meter set on dc milivolts a brand new thermocouple should test @ 30 milivolts+ - ! & if you have new style water htr with sealed combustion the thermocouple has a safety part of it ! change the thermocouple & make sure your vents for combustion air around the bottom of the water htr has lint & dust built up !!! kiddbrother i work for a gas company doing service !!
