Gah! A *hole* new problem (LPG leak)

So we're living in our rv for ten days (which we are still fixing up, waiting on new chassis batts and inverter)..

My wife smelled propane outside, so we went exploring. After some sniffing, soap and flashlight fun, we discovered this hole, in what I am assuming is the LPG regulator.

My question is.. Why is propane flying out of it? The hole looks like it was meant to be there.. so is it a matter of tweaking some knobs? or is the regulator pooped?

Thoughts?

Here's a picture of the culprit:

It is a vent hole, usually to allow atmospheric pressure to the back side of the rubber regulator part inside. If it is leaking out of there, time to replace the regulator.

They are not expensive, only around 30 to 40 bucks, and seldom last more than 20 years safely. Just more maintenance on the older rigs we have.

Turn off the tank, bleed the pressure out of the lines...

There is a little rubber diaphram in the regulator which is the sensing element to set your pressure at 11 inches of water. The rubber deteriorates over time and can develop a hole. The regulators are not field serviceable and you need to replace the whole thing. Buy one with an automatic switch over feature, so you do not have to get up in the middle of the night to change the valves to use the other tank.

dwightdi, with 'us' motorhome owners, we don't have multiple tanks to require the need for a switchover feature. My 345 has a 125lb tank.
Thanks, Derek
