I replaced the pressure regulator on my gas stove because I keep detecting a leak at the center of the cap in the regulator (when testing for leaks). Now the new one I installed also shows a leak from the center of the cap (because I tested for leaks after installing) So my main question is, is there supposed to be a venting of air or something there (other then gas) that I would be detecting when testing for a leak? Or is the new one bad too? I just can't understand why it would be leaking from the center of the LP/Nat cap. Thanks

Hi Gene, Thanks for asking.

I used a liquid leak detecting solution for gas pipes. With this one it fizzes white for a small leak, or produces a bubble or bubbles at leak site with a bigger leak. After the solution sits on area being tested for a couple of minutes.

I detected a bubble when I placed the leak solution inside the LP/Nat cap under the dust cap in the center of the regulator.
Part # is 316091706

Thanks

Ok no problem. I just lifted the dust cap off and sponged the liquid tester inside the LP/Nat cap, I did not unscrew the cap out of the regulator to test. It then produced a bubble in the LP/Nat cap while it is still screwed into the regulator.

The original problem was that I smelled a faint gas smell. So I checked all orfices on the stove, all connections and the only leak I found was on the LP/Nat cap on the regulator. So I replaced the regulator, and tested for leaks on all connections and then put some liquid on the screwed in LP/Nat cap on the regulator. (of the new one) Low and be hold I got a leak positive with the new regulator cap location. Just like the old one

Thanks
Chris

Thanks for all your help. I was able to fix it last night

Chris

I thought it was fixed but not so Gene.

So the propane company came over and found a leak in the main propane pipe that comes in behind the oven. I fixed that while they watched because apparently they won't do the work. There was still a faint propane smell from the regulator so then I noticed that the hole in the center of the cap still faintly leaks (same problem I was already having). The propane guy told me to call a gas tech and they wouldn't fix that either.

So I have some questions maybe you can help me answer.

Why is there even a hole in the center of that cap in the pressure regulator ? Is that so as the diapham collapses it can let any gas out that is trapped ? Can I just seal the hole in the cap and all problems fixed ?

I'm getting to the point where after putting in a new pressure regulator and still having the same problem I'm going to go buy a new oven. There is no way I want to faintly smell propane from the bottom of the oven all the time.

I can usually always fix everything, but this one is bugging the heak out of me.

Thanks
Chris
