Easy to change out, just be care full not to break the 1/4' street elbow to 1/2' male flared fitting. Its made of brass and hard to find. Don't ask me how I know.

Jennifer, did you replace the regulator yourself or have shop do the work?
Easy / tricky??
No shop for this job.  Very easy, no special tools needed except for the home-built manometer, which can be made with just some scraps of lumber and a few dollars of tubing.  The longest part of the job was trying to use up the remaining propane.  Other than that, just a few fittings to remove/replace. 

I hate to see you do all this if your other propane appliances are all working properly.  But I suppose if you want to eliminate this potential issue, no harm in replacing these items, since they seem to need replacement eventually, anyway.

The WH seems to be working , but for $30 it seems prudent.
Did you use any tape or paste on the connections?

Never us tape on gas or air fittings as tiny fragments of the tape can plug valves and orifices.

No tape use gasoila soft set thread sealant. That is what my son who works with propane recommended it works

Where can you purchase gasoila and don't tell me amazon. Sounds like would work well on air fittings too. Better than rectorseal?

Never used rectorseal so cannot make a comparison. But I did find a site that will sell you a half pint of Gasoila for $45 or you can get the same thing from Amazon for half that. Your choice. Do a web search and DWMYH

I used a little brush-top can of thread seal, not exactly sure of the name.  It was noted to be for LG gas fittings.  But if I knew about that Gasoila, I might have gone with that.  It looks like it would be a good choice, lots of benefits, especially for an RV application.

It's okay to use the yellow teflon tape on pipes carrying petroleum products, like LP gas lines. Don't use the white teflon tape on petroleum pipes because teflon is a petroleum product itself and the gas / oil will break it down and eventually cause a leak. The yellow teflon is sorta new, within the past 20 years I think? It used to be a federal law that you couldn't use (white) teflon tape on LP gas lines for bobtail gas delivery trucks or tankers. We had to use pipe dope instead. Apparently this all changed since I worked on LP gas trucks.

As previously stated, teflon tape can break loose and get stuck in a valve. I found teflon tape was causing a check valve to leak on my coach. Whoever installed the check valve used way too much teflon tape. I put it back together with a more reasonable amount of teflon tape and it's been working fine ever since. Just use common sense and don't leave any excess teflon tape to break off.

Be sure to soap suds test every joint you disturbed. Give it a minute and then look again to see if there's a bubble forming. The gas is under very low pressure so it won't be a gusher of a leak. It'll just be a tiny seepage. Don't over tighten any of the fittings or you'll cause a leak. It takes some skill and experience to know how tight a fitting needs to be. If it leaks only tighten it enough to stop the leak, then test it again and give it a minute to be sure you stopped the leak completely.

Very well said,  and I agree with you 100%, when property applied by a pro just don't start Teflon tape until maybe after 3 thread engaged. Nothing wrong your idea of Teflon. Just better options out there.

Yup, applied by pros, Teflon works fine. I quit using it years ago because my crew figured, "if a little works, then more is better."

Just another twist I removed the round window disc used to view the flame with WH door closed , I thought it would eliminate the lack of air theory.
Flame still slowly dies then re lights !

Check for a hole in the exhaust flue that would allow flue gas nearly completely devoid of oxygen to get back into the burner compartment. It's the path of least resistance.

Still sounds like a regulator problem, only real way to tell is with a manometer on the gas valve to see if the pressure is staying up or falling down. Or you can just put on a new one they are relatively cheap.

You could, but I am pretty sure she will get her hands on you long before she finds me. Bigger risk is she might boot you out of it and disappear herself.
