What you should know about the safety of gas lines and sewers.
Unless your natural gas line crosses your sewer pipe, a sewer backup is usually simple to correct. Sewer-clearing machinery can cause damage to the gas line, allowing natural gas to leak into your sewer system and into your home.
Call a professional plumber to scope the sewer line with a video camera if you suspect your natural gas and sewer lines are crossed.
Cross-bored sewer pipes are typically inspected by gas providers. A door hanger notification from some gas companies may be left in the neighborhood, indicating when they will be in the area. If a problem is discovered, the gas company will repair the sewer line and reroute the gas line at no cost to you.
