Keep reading to learn about this inspection and its process, and when it’s absolutely necessary to contact a reliable inspector.

What Is a Gas Pressure Test Inspection?

A gas pressure test inspection ensures your house’s gas line pipes, joints, fittings, and other components are intact and functional.

This inspection is usually done before the pipes are connected to the main gas source to prevent leaks and explosions. However, after general home inspections, the report may mention that this inspection is needed due to specific reasons (e.g., old plumbing or natural disasters).

What Do LP or Natural Gas Pressure Test Inspections Include?

First, the inspector will assess everything visually. The most important part of the process includes verifying whether the lines can maintain a certain PSI for a specified time. The required PSI depends on the lines’ type and the system’s size, while the specified time varies based on local codes and regulations.

The inspector will pressurize the gas line using air (pneumatic) or liquid (hydraulic/hydrostatic test) and check for leaks or pressure loss. They’ll examine all joints, fittings, and valves to make sure they can hold the pressure safely. This procedure may also involve measuring gas rates, burner pressure, and examining safety components.

Why Do I Need a Gas Pressure Test Inspection?

Many things can damage gas lines and their components. Corrosion, mechanical damage, environmental factors, pressure fluctuations, improper sealing, or simply degradation over time, all can compromise the integrity of your system.

Gas pressure test inspections help identify leaks that could cause your gas bill to surge, or even explosions and asphyxiation. It ensures the gas system is working at optimal pressure and there’s no energy loss.
