Pressure Test Checklist
Pressure Test Checklist
Quick Summary
A pressure test checklist helps crews verify that piping systems are properly installed and capable of holding pressure before being placed into service. It provides a consistent process for preparing, conducting, and documenting tests while identifying leaks or installation issues early. This checklist is useful for plumbing contractors, mechanical contractors, utility crews, foremen, and project managers.
When to Use This Checklist
- Before rough-in inspections.
- After pipe installation is complete.
- Before insulation, drywall, or backfilling work begins.
- Prior to commissioning plumbing or mechanical systems.
- After repairs, modifications, or system expansions.
- As part of project quality control procedures.
Before You Start
- Review project specifications and testing requirements.
- Verify all piping installation work is complete.
- Confirm all required fittings, valves, and connections are installed.
- Verify test equipment is available and functioning properly.
- Identify testing boundaries and isolation points.
- Notify affected trades and project personnel.
- Verify access to all areas that require inspection during testing.
- Review inspection scheduling requirements if applicable.
Safety Checks
- Inspect hoses, gauges, pumps, and test equipment before use.
- Verify all temporary test connections are secure.
- Keep non-essential personnel away from active test areas.
- Verify workers are using required PPE.
- Inspect exposed piping supports before pressurizing the system.
- Confirm test pressures match project requirements.
- Establish communication between crew members during testing.
Tools, Equipment, and Materials
- Pressure test pump or air testing equipment.
- Calibrated pressure gauges.
- Test plugs, caps, and isolation devices.
- Hoses and temporary test connections.
- Project specifications and testing procedures.
- Inspection forms and test reports.
- Camera or mobile device for documentation photos.
Pressure Test Checklist
- Verify all piping work within the test area is complete.
- Confirm valves are in the correct position for testing.
- Install required test plugs, caps, and isolation devices.
- Verify gauges are installed and readable.
- Inspect all visible joints, fittings, and connections.
- Gradually introduce test pressure according to project requirements.
- Monitor pressure readings during stabilization.
- Inspect piping system for visible leaks or pressure loss.
- Check fittings, valves, and connections for signs of leakage.
- Verify supports and hangers remain secure under test conditions.
- Maintain test pressure for the required duration.
- Record pressure readings and test duration.
- Document deficiencies or leaks discovered during testing.
- Complete repairs and retesting if required.
- Verify system passes all project testing requirements.
Documentation Needed
- Pressure test reports.
- Pressure readings and test duration records.
- Inspection approvals and sign-offs.
- Photos of the testing setup and completed system.
- Leak repair and retest records, if applicable.
- Project specifications and testing requirements.
Common Mistakes to Avoid
- Testing before all piping work is complete.
- Using damaged or inaccurate gauges.
- Failing to isolate the correct test area.
- Overlooking small leaks during inspection.
- Skipping documentation of test results.
- Failing to retest after repairs are completed.
End-of-Day / Final Review
- Pressure testing has been completed according to project requirements.
- All leaks and deficiencies have been addressed.
- Retesting has been completed where required.
- Photos and supporting documentation have been uploaded.
- Inspection records and approvals have been collected.
- The piping system is approved for the next phase of work or service startup.
