Plumbing Commissioning Checklist

Use the Plumbing Commissioning Checklist to ensure all plumbing systems are properly installed, leak-free, and functioning, including fixtures, pipes, etc.

1. Is the supplier's consolidated delivery ticket available, showing all equipment and ancillaries for inspection and used for verification?

2. Is a copy of the order sent to the supplier available for reference and used for verification?

3. Is the pipework packaged with end caps to protect the internal surfaces?

4. Does the pipework have the correct wall thickness?

5. Does the pipework have the correct flanges?

6. Is the pipework dry internally?

7. Is the pipework undamaged?

8. Are the pipework surfaces clean and not scratched?

9. Has red oxide paint been applied where required, and is it in good condition?

10. Are all ancillaries included in the delivery as per the order and delivery note?

11. Has any protection been removed?

1. Is the area internal and protected from weather?

2. If the pipework is stored externally, is there sufficient protection to shield it from weather and ambient conditions?

3. Is the surface where the pipework is to be placed flat?

4. Is the area well covered and protected?

5. Is the area well-ventilated with no risk of high humidity?

6. Is the area clean and dust-free?

1. Will the pipework not be over-stacked?

2. Will no materials be stacked on the pipework?

3. Will all ancillaries be placed in a safe and secure location to prevent loss or damage?

4. Are pipework/connection caps protecting the flanges not removed?

5. Will the pipework be raised from the floor to allow airflow and prevent water ingress?

1. Is the bracketry ready, able to bear the weight of the installation, and spaced correctly?

2. Is the room/area dry and watertight?

3. Is the area where the installation is being done not prone to flooding or water ponding?

4. Is the room/area where the pipework will be installed clean and dust-free? If there is dust or construction work, is the pipework protected from concrete dust, cement, etc.?

5. Are all connection kits, including gaskets and bolts, available to allow bolting up of the pipework?

6. Is the pipework clean and free of damage?

1. Is there enough space around and above the pipework once installed to perform maintenance and remove components, where required?

1. Is the pipework installed in line with the project drawings (size, location)?

2. Is the piping free to expand and contract without noise or damage to hangers, joints, or the building?

3. Are seismic restraints installed where required?

4. Does the pipework avoid putting undue stress on connected equipment and is it bracketed to support itself?

5. Do all piping supports and hangers meet the criteria set out in the specifications?

6. Is the piping installed with sufficient pitch and arranged to ensure proper drainage and venting of the entire system?

7. Are manual air vents provided at high points in closed water systems?

8. Are all gaskets installed and sealed?

9. Are all bolts installed as per the manufacturer’s instructions?

10. Are nipples made of the same material as the pipe?

11. Are connections between copper and steel pipes made with dielectric fittings?

12. Is a union provided ahead of each screwed valve, trap, or strainer, and on each side of each piece of equipment, as needed to dismantle the piping?

13. Are changes in pipe sizes made with proper size-reducing fittings, reducing elbows, or reducing tees? Are bushings avoided?

14. Do all fittings meet specification requirements?

15. Are all fittings and ancillaries rated correctly and in line with the pressure of the system?

16. Is all equipment requiring maintenance accessible (e.g., valves, junction boxes)?

17. Does the piping avoid blocking access to equipment that is part of this system or another system (e.g., air terminal units)?

18. Are drain valves provided at all low points in hose bib piping to facilitate seasonal draining?

19. Are all valves (isolation, commissioning, non-return, etc.) installed as per the drawings?

20. Are all strainers installed as per the drawings and are the baskets clean?

21. Is the pipework insulated as per the specification and vapor sealed where required?

26. Are all pressure gauges installed and displaying scales as per design requirements?

27. Has the pipework been magnetic weld tested, where specified?

28. Has the pipework been ultrasonic weld tested, where specified?

29. Has the system been filled and bled with air removed?

30. Has the pipework been pressure tested?
