Hi, I have a small gas leak from my gas regulator feeding my heaters. The gas goes from holes on a vent bolt. You can see a bubble on an attached picture. The leak is slow - one bubble per 5 seconds. My question - is it normal, if not, what is a potential problem. And finally, should I replace the regulator, or my be I need just fix something (tight the vent bolt, for example). If a replacement is required, I'll call a plumbing company, but before that I want to understand the problem to avoid unreasonable charges.
Usually that vent hole is to allow air in the chamber of the diaphragm so it can move up and down and regulate. If gas is coming out then the internal diaphragm has pinholes in it and the regulator is unsafe and needs replacing.
