Solar collector panels can be orientated within 90 degrees of north, due to a recent amendment made to the Standard Plumbing and Drainage Regulation 2003. The amendment is referred to as the Standard Plumbing and Drainage (Solar Heated Water Systems) Amendment Regulation 2017.
A joint investigation by the QBCC and Queensland Health has revealed that home owners are often not aware that hot water systems need to be serviced regularly.
Plumbers should remind home owners that it is generally recommended for hot water systems to be serviced by an appropriately licensed individual. Where the source water for the system is not a potable, reticulated source, the system may need to be serviced more frequently.
Hot water heater replacements have a high rate of non-compliance, with up to 40 percent of installations failing to meet required standards. While many defects are minor, such as a lack of an appropriate point of discharge for the overflow, this large number of non-compliant installations is a major concern.
The QBCC has started tackling this issue by asking local governments from across Queensland to identify some of the main issues of non-compliance that their plumbing inspectors find during inspections.
