Natural Gas line vent, Shutoffs...
Or gas meter is in our basement, and from the regulator there's a 20+ ft long 3/4" line to our outside wall exiting about 40 inches above the ground. Where it exits the house at the approximate height on the corresponding inside wall is a small grill, (3" x5") which is apparently open to the air since in this windy weather today I can feel a little breeze blowing. GIven that it's also near the plumbing stack vent, I'm thinking perhaps this is not a vent for the gas line but for the plumbing stack(?). GIven the investment we've put into insulation, I would like to cover this grill but not before I get some advice. Is the indoor grill for internal pressure relief during a gas leak?
Also in looking to attach a wrench or vice grip to either the meter or regulator's emergency shutoff valve, the regulator's shutoff looks easier--easier to reach and on a horizontal plane. I would assume either shutoff would do the job. Any preferences?
