Pressure testing cold water pipework

All water fittings should be capable of withstanding an internal water pressure of not less than................ times the maximum operating pressure.

• 1.2

• 1.5

• 1.7

• 2

When testing rigid pipe systems all the outlets should be sealed and all float operated valves should be capped off or isolated.

The water pressure should then be increased, by pumping, until the lowest point in the installation is 50% above the normal operating pressure. This pressure should be maintained for..................... without further pumping.

• 30mins

• 1hour

• 1.5hours

• 2hours

Which of the following problems should be rectified before testing?

• Insufficient clips

• Lagging pipes

• incorrectly installed service valves

• Make sure you have open ends

Once a hydraulic test bucket has been used to pump up the pressure to the correct test pressure, how long should it be left for?

• 30mins

• 1hour

• 1.5hours

• 45mins

How many tests are there for systems containing plastic pipe?

• 1, test A

• 2, Test A and test B

• 3, Test A, B & C

• 1, same as the rigid pipe test

Test A is passed if the pressure does not drop below one-third of the test pressure over the following............... minutes and there is no visible leakage throughout the test.

• 60mins

• 90mins

• 120mins

• 45mins

The customer should be issued with which of the following documents during the handover:

• The bill

• Manufacturer's instructions

• Warranty

• Benchmark
