Common Gas Line Service Questions

No, you cannot plant a tree above a gas line. Tree roots grow and spread over time and can sometimes dent, crack, or penetrate a gas line. Those same roots may also cause accessibility problems for maintenance or repairs. You can generally plant vegetation with non-invasive root systems, low-growing vegetation, and flower beds near gas lines. 

While some building codes allow galvanized pipe for natural gas, it shouldn’t be used for propane. Propane can cause the pipe to wear down, leading to dangerous leaks. Instead of galvanized piping for propane, you should consider coated copper, black iron, or corrugated stainless steel tubing (CSST). For underground propane line installation, you can use polyethylene (PE).

Installation typically takes 1-2 days, and repairs can often be completed on the same day, depending on their complexity.

Common signs of gas line leaks include a rotten egg smell, hissing sounds, dead plants around the area of the leak, and unexplained physical symptoms like dizziness and nausea. If you notice any of these signs, act immediately. Shut off the gas supply to your home and call a pro to assess the situation.

If you're connecting your gas line to appliances, the pro doing the work may recommend flexible corrugated stainless-steel tubing (CCST). Polyvinyl chloride (PVC) with high-density polyethylene (HDPE) is another relatively inexpensive material commonly used for residential pipes. Ultimately, you'll need to find out what is permitted based on the code requirements in your area.
