What to know about leak detection in Adelaide
Modern leak detection uses a combination of acoustic listening devices, thermal imaging cameras, tracer gas, and pressure testing. Different tools for different leak types - network plumbers carry the kit appropriate for residential work.
Backflow prevention device installation and annual testing requires a plumber with SA Water backflow accreditation. Every commercial property in Adelaide and many residential properties with a connected irrigation system require it.
If the leak is on SA Water's side of the meter, SA Water investigates and repairs at no cost. Network plumbers will confirm which side the leak is on before quoting.
South Australian regulation
Backflow prevention device installation and testing requires a plumber with current SA Water backflow accreditation in addition to PGE Act plumbing registration.
Leak Detection in Adelaide - questions
Standard electronic leak detection visit: $280 to $480 for residential. Complex jobs (multiple suspect lines, thermal imaging, slab work): $650 to $1,100. The leak repair itself is quoted separately once the location is confirmed.
Yes - thermal imaging detects temperature differential where warm water has tracked through the slab. Acoustic detection picks up the hiss of pressurised water escaping. Network plumbers use both as needed.
Not necessarily. Once the leak is located, options include relining the affected pipe, repairing through a small access hole, or running a new line through the wall cavity. Slab demolition is the last resort.
SA Water investigates leaks on the public side of the meter (free). Anything on your side of the meter - your responsibility, but our network plumbers handle it. They'll also work with SA Water if the leak is on the boundary.
Failing or unmaintained backflow prevention devices can leak. They must be tested annually by a plumber with SA Water backflow accreditation. Network plumbers carry this endorsement.
