PPT 9 - Install and test systems and components

What is one of the requirements for a plumbing system after installation?

• It must be painted.

• It must be sound (no leaks).

• It must be expanded.

• It must be insulated.

What does "flushed through" mean in the context of plumbing?

• Painted externally

• Cleaned internally

• Expanded in size

• Insulated properly

What does "disinfected" refer to in plumbing system testing?

• Mechanically cleaned

• Painted with a sealant

• Chemically cleaned

• Expanded for more capacity

What does "commissioned" mean in the context of plumbing?

• Set up correctly

• Painted and sealed

• Expanded and insulated

• Mechanically adjusted

What is the first step in the testing process?

• Visual inspection

• Soundness test

• Deccomission

• Flushing out

Which step comes immediately after the soundness test in the testing process?

• Visual inspection

• Flushing out

• Disinfecting

• Hand over to customer

What is the final step in the testing process before handing over to the customer?

• Commissioning

• Visual inspection

• Soundness test

• Flushing out & Disinfecting

What should you visually check for before conducting a soundness test in plumbing?

• Open ends, soldered joints, compression joints, and clips

• Water pressure, pipe color, and temperature

• Pipe length, diameter, and material

• Electrical connections and insulation

What is the first step in soundness testing for rigid pipes according to BSEN806?

• Attach the hydraulic test bucket.

• Slowly fill the system with water.

• Pump the system up to 1.5 x working pressure.

• Check for any pressure drop.
