    If the replacement doesn't have the nut you need (Some "universal" units aren't totally universal, just cut it with a pair of wire cutters to remove it.

    Use two wrenches. Nuts are locked together. Replace the whole thing , including the brass fitting   ?

The thermocoupler doesnt have any removeable parts. it threads directly in the valve itself

Rheem gas water heater pilot light went out when i tried to relight it does not light up again.

Usually if they won't re-light it's a problem with the orifice on the pilot itself. The thermocouple won't cause it to re-light but it will prevent it from staying on after being lit. Just make sure you have valve set to pilot when you press the red button down to light. You can take out the burner by removing the gas and thermocouple lines, unscrew the orifice and use like a wire brush bristle to clean out the hole in the orifice.

Pilot Orifice

Okay you don't ream pilot injectors hence the 3 inch pilot which is now no good to you nothing to be done with that .

Take you manual to heating / plumbing shop tell them you need a new injector for you pilot block they might be able to sell you just the injector or a new pilot block Most pilot injectors are the same size . Or get you gas fitter back to replace it as the injector was only blocked and needed a clean . in 40 years of gas fitting I have never reamed a injector .

Bosch 1600p pilot orifice

Definitely do not use should never ream out an injector since it obviously meters the gas coming through. 8708200005 is the part number for the NG orifice, 8748200173 is the part number for the LP orifice.
Bosch parts are available through a company called in The USA, and Target Wholesale or Astravan Distributors in Canada

Richmond 3360 gas water heater pilot won't stay on

Open following links for pilot and troubleshooting resources:
Problem could be bad thermocouple, thermocouple not sitting in pilot flame, pilot orifice needs to be cleaned, water heater needs more air, dirty air intake, hot attic environment, backdraft blowing out pilot, or bad gas control valve.
If you get flame, then ECO is not tripped.

My Rheemglas fury 21DV50 hot water heater pilot goes out about every 2 days for the last week and 1/2. It will light and I'll be able to have hot showers but doesn't last more than about 2 days. Is it the...

It could be a thermocouple but first take the whole pilot assembly out and disassemble it. Clean it very good (compressed air is ok) especially the orifice inside the pilot horn. You may just have a weak pilot. If the flame is in good contact with the thermocouple and problem still exist, then change the thermocouple. I believe in doing the free things first.

Pilot light not staying lit, changed thermocouple, start up proceedure normal until the pilot button released.

Some things to check:

Make sure the thermocouple is squarely in the pilot flame and that the pilot flame is large enough to envelop the thermocouple. A weak pilot can be caused by gas pressure or a carboned-up pilot orifice (where the gas comes out). The orifice may need to be cleaned. Ordinary automotive carburetor cleaner will work. Don't try to stick objects into the orifice - damage may result. If you need to perform this step, make sure the gas is turned off to the heater first.

Make sure the other end of the thermocouple is clean and tight in the gas valve.

Hold the pilot plunger down for at least a minute to be sure to give the thermocouple enough time to heat up.

Cannot get the pilot light to stay lit

This can be two common things:

1. Carbon buildup at the pilot orifice (where the gas comes out). This can be cleaned with carburetor cleaner, but make sure the gas is off first (important!).

2. The thermocouple is either bad, displaced or it too is carboned up like the pilot assembly described above.

If you clean everything and the pilot still keeps going out, replace the thermocouple. Make sure the thermocouple is squarely in the flam path.

Pilot goes out after heat cycle, relight and it stays burning untill next heat cyle has run.

This sounds like a dirty pilot jet orifice or a weak thermocouple. The pilot orifice can carbon up (natural gas is a fossil fuel), become weak and keep going out whenever the main burner lights, which causes a pressure drop in the gas line. The thermocouple can also become dirty and not sense properly.

The pilot light assembly should be cleaned. The gas must be turned off and it's best if the pilot assembly can be removed. Automotive carb cleaner can be used to clean the orifice. Do not try to insert any object into the pilot orifice valve as this can result in damage.

If cleaning does not resolve the problem, replace the thermocouple first. Make sure it is installed correctly and is squarely in the pilot flame.
