Plumbing regulations

Every part of your plumbing system is bound by rules and regulations. In turn, every task your plumber performs is also bound by Australian Standards (AS3500 and 5601) and the Plumbing Code of Australia. Failure to comply with these Standards could land your plumber or appliance manufacturer in a great deal of hot water (if you'll pardon the pun), and could also have dire consequences for your safety and that of your home.

While you're not expected to know all of the regulations inside and out, understanding the basics can help you ensure that your plumbing's what it's meant to be.
