Gas Pressure Testing & Gas System Inspections
Quick, reliable plumbers always on call.
SoCal Sewer and Water provides gas pressure testing and gas system inspections for residential and commercial properties following suspected leaks, repairs, utility shutoffs, remodeling, appliance installations, and gas piping modifications. Pressure testing provides measurable evidence of whether an isolated gas piping system can maintain pressure without an identified loss.
What Does Gas Pressure Testing Do?
The piping system is isolated and tested using an appropriate pressure and procedure. If the system loses pressure beyond acceptable limits, additional investigation may be necessary. A gas pressure test determines whether the piping holds pressure; a system inspection evaluates visible components and conditions that may also require attention.
Gas System Inspections
Accessible components may be evaluated for:
- Corrosion
- Damaged piping
- Shutoff valves
- Pipe supports
- Connections
- Appliance connectors
- Questionable modifications
A system can potentially pass a pressure test while still containing visible conditions that deserve correction.
When Testing May Be Required
Gas testing is commonly performed after:
- Gas leak repairs
- Re-piping
- Appliance additions
- Remodeling
- Utility shutoffs
- New gas installations
Residential systems may serve water heaters, furnaces, dryers, ranges, fireplaces, and pool equipment. Commercial systems can be much larger and may serve restaurant equipment, boilers, industrial equipment, or multiple tenants.
What Happens if the System Fails?
SoCal Sewer and Water can isolate sections of piping and investigate the suspected leak area. Once repairs are completed, the affected system can be tested again. Gas safety should never be based solely on smell or assumption. Measurable testing combined with visual inspection provides a more reliable basis for determining whether a gas system is ready for normal operation.
