Gas pressure testing and gas system inspections help determine whether a residential or commercial gas piping system is capable of maintaining pressure without leakage. These services may be required after repairs, modifications, utility shutoffs, equipment changes, or when a possible gas leak is suspected.
Because combustible gas systems present serious safety concerns, testing should be performed using appropriate equipment and procedures.
What Is Gas Pressure Testing?
Gas pressure testing isolates the piping system and introduces an approved test pressure so the system can be monitored for loss.
If pressure decreases beyond acceptable limits, additional investigation is needed to identify the leak or failed component.
Test procedures vary depending on system type, jurisdiction, piping material, and reason for the inspection.
When Is Gas Pressure Testing Needed?
Common situations include:
- After a gas leak repair
- Before gas service is restored
- After adding or modifying gas piping
- During remodeling
- When installing new gas appliances
- When unexplained gas odor has been reported
- When required by a utility or local authority
