Air release ventsVent type: Provide manual vents except where automatic vents are documented.

Location: Provide 15 mm minimum size air release vents at the following locations in water systems:

- High points of the system.

- Sections of the piping in which air may collect.

- Upstream from each item of heat exchange equipment.

Water system risers: Provide a 150 mm high riser set vertically from the pipe and fabricated from the same diameter and material as the pipe. Provide an automatic air vent at the top of the riser.

GradingWater systems: Grade to rise in the direction of flow to points of air venting, except where the water piping is exposed in a run with other services, in which case run the water piping to the same grade as the other services.

- Minimum grade: 1 in 200.

07 MECHANICAL 0411 Waterproofing – external and tanking

Proximity to other servicesGeneral: Separate underground piping from electrical cables and gas pipes, by at least 300 mm.

InstallationPipe underlay: Bed piping on a continuous underlay of bedding material, at least 75 mm thick after compaction. Grade the underlay evenly to the gradient of the piping.

Bedding material: Sand free from material retained on a 13.2 mm sieve.

Chases: If necessary, form chases to prevent projections such as sockets and flanges from bearing on the trench bottom or underlay.

Other services: Separate underground piping from electrical cables and other services by ≥ 300 mm.

Pipe surroundsGeneral: Place the material in the pipe surround in layers less than 200 mm loose thickness and compact without damaging or displacing the piping.

Protection: Lay continuously concrete tiles more than 25 mm thick, or PVC tape at least 3 mm thick, in the overlay, 50 to 75 mm clear of the piping, for the length of the piping.

Warning tape: During backfilling lay plastic warning tape 300 mm above buried piping, for the full length of the piping.

- Type: Minimum 100 mm width.

ValvesInstall in underground control boxes.

Corrosion protectionProtection: Either encase piping in continuous PVC-U watertight pipe or provide continuous wrapping over all pipe and fittings using proprietary petroleum taping material installed in accordance with manufacturer's recommendations.

3.10 TESTING

Completion testsCold water: To AS/NZS 3500.1 Section 17.

Wastewater: To AS/NZS 3500.2 Section 13.

Pressure piping as defined by AS 4041: Hydrostatic test.

Condensate drains from cooling coils: Hydrostatic testing is not required.

Hydrostatic testingPreparation for testing: Isolate items of equipment not designed to withstand test pressures. Leave pipe joints exposed to enable observation during tests. Secure pipes and fittings in position to prevent movement during tests. Restrain expansion bellows.

Water pre-treatment: Conform to 0753 Water treatment. For steel piping, introduce corrosion inhibiting chemicals. Use chemicals from a water treatment specialist in conformance with the specialist’s instructions and under the specialist’s supervision. Leave pre-treated water in the system until the system is ready for chemical cleaning and flushing.

Procedure: Test completed piping systems including equipment designed to withstand test pressures. Isolate equipment not designed to withstand the test pressure.

Test criteria: No leaks or loss of pressure over the test period after taking account of changes in ambient temperature.

Test pressures: To AS 4041.
