Well... as we prepare to take our new 2910T out for an overnight "shakedown", I had the propane tank filled.  The gentleman said he filled it to the max and I should be good to go for awhile.  I brought the coach home and turned the tank on so that I could get the refrigerator cooled overnight.  When I turned it on, the propane just ket coming out from the open/closed knob.  Anyone have any clue what is happening here.  Thanks in advance for your help.

I have not heard of this before. Atwood does have a service number 815-877-5700. I'm sure you've already shut off the propane.

Wish I could help.

Thanks George... I did shut off the valve but I'm still a little nervous about using the coach until after I get it looked at.

Joey:

I am a little confued as to what you are calling the "knob" that you are turning open/closed?  There is a bleed screw that is used to bleed air off during the filling process,  you are not turning that open/closed by mistake are you?  You should be turning the handle on the left side of the tank.  I suppose the packing in the stem could be bad but I have never heard of that happening ever.

Boy this sounds serious.  You surely must resolve this to use propane.

Moments ago I just looked at the propane valve on my PC in the garage.  I would get a small adjustable wrench, or better yet, the right sized box wrench, and make sure all fittings are tight, including what is hidden behind the white plastic shield.  The last fitting to check is the one right behind the turn handle itself.  You must have the valve wide open in order to get the wrench on that one.  With all other fittings checked first, this would be the last one.  Opening the valve to check that fitting, your leak might already be resolved.

Once all fittings are checked to be tight, you can safely check for leaks by pouring soap suds over all fittings.  Watch for bubbles.  Dish soap works good for that.

If you do this all, please report back as to your findings.  Hopefully it's a very simple solution that a simple tightening with a wrench resolves.  That is much easier than getting someone else involved.

Thanks everyone... This morning I decided to remove the regulator "box" and investigate the leak a little further.  After doing so. I turned the Open/Closed knob to the open position and low and behold, gas come flowing out the vent hole at the bottom of the regulator.  The question I have is why and what do I do next.  I have attached a picture.  Again, thanks a million for all your help.

Joey,
I would email the picture to KERMIT@Phoenixusarv.com or Amanda@phoenixcruiser.com. Amanda gets in earlier than Kermit and she will get the photo to him as soon as he gets in.

Is the tank more than 80 percent full? It should not be if it is. Look at the gage on the tank, not the inside meter. Kermit might ask the same question. To fix it, you have to bleed off the extra using the small valve in a very open area. No flames near by. Some dumpy guys try to fill the tank to full, which does not allow for expansion.

I recently had my tank filled, and the guy overfilled it (thought that wasn't possible with the new tanks, but it is).  When we got to our first campsite, I could smell propane.  The meter on the tank showed 100% full.  I bled off enough propane with the filler vent valve to get it down to 80%.  No problems after that.

Awesome service... I sent an email to Kermit with cc to Amber on Saturday outlining my Propane regulator problem.  Monday morning at 8AM, I receive a call from Stuart making sure that I do what ever it takes to get it fixed properly at his expense.  He also re-embursed the the campground deposit I lost because I cancelled.  I haven't camped a night in my unit yet and I can't say enough good things about PC. 

Regarding the propane issue; the regulator diaphragm was defective.  Some of you also noticed a sharp bend in the gas hose where it connects.  That is also being taking care of.  The shop is putting a brass L-joint (or something like that) between the hose and the regulator.

If the valve was open when the tank was "over" filled that most likely ruptured the diaphragm.  The propane supply pump has to provided more pressure than the system downstream from the tank is capable of withstanding just to fill the tank.  When it was filled beyond the 80% point and the tank became full, the system essentially became full of an incompressible liquid, and one side of the regulator being open to the atmosphere the diaphragm provided the weak link.
When vapor comes out of the "vapor port" the filler should have stopped filling, relying on the tank overfill mechanism is kinda scary, and I have had a couple  of the overfill valves go bad from environmental thrashing, i.e., propane when low, sloshing and ruining the float mechanism.
FYI there are other regulators downsteam of the tank regulator, check them for leakage too.
