The local gas company....saw cut my heated car wash aprons without calling me....cutting several lines. They were replacing something that required the aprons to be cut. So now, after 30 years of flawless service, it obviously has to be repaired before winter. What cautions need to be observed? I need advice. I don't want them to put the wrong kind of repair coupling in there....pour concrete around it...and in 5 years...have issues. Is this a big deal, or a simple patch?
