When all reasonable efforts have been made to locate and fix the leak(s), and provided there is no smell of gas, an allowable leakage rate assessment can be made in accordance with this sheet. Such leakage is often due to a combination of old appliances, worn gas cocks and weepy pipe joints. Sometimes however, slight leakage occurs which is hard to detect. Gas leaks should be identified using a soapy water solution, leak detection fluid or other suitable leakage detection method. Finding gas leaks and when to apply the allowable leakage rate Methods for leakage tests are explained in AS/NZS 5601.1 Appendix E. If a leak is found then arrangements can then be made for the fault to be fixed before the new work is connected.

The purpose of this sheet is to provide guidance on how to apply an allowable leakage rate to an existing standard natural gas installation up to 30 litres at a maximum operating pressure of 1.275 kPa ± 50 Pascals. AS/NZS 5601.1 Gas Installations Part 1: General installations requires all existing gas installations which have been altered, repaired or extended to be tested for leakage.
