Pipe Relining Cost
Pipe Relining Cost in Adelaide
Per-metre relining cost runs $450 to $650 in Adelaide. A typical 6-metre domestic job is $2,700 to $3,900 - often half the cost of dig-and-replace once you add lawn, paving, and driveway restoration.
What you are really paying for
Pipe relining is the modern alternative to digging up your yard. A flexible liner is impregnated with resin, inserted into the damaged pipe through an existing access point, inflated, and cured to form a new pipe inside the old one. For most Adelaide homes with root-damaged sewer pipework, it's the right call.

What moves the price in Adelaide
- Most Adelaide heritage suburbs (Norwood, North Adelaide, Prospect, Unley) have original clay sewer pipework - prime relining candidates.
- Outer LGAs may have longer pipe runs requiring more material.
- Network plumbers handle SA Water cooperation for any work near public connections.
- Adelaide council reinstatement requirements (lawn, paving) are usually unnecessary because relining is no-dig.
Pipe relining is approved under AS 4956 and the SA Plumbing Code as a structural repair. Most jobs come with a 50-year warranty - longer than the original pipe in many cases. The cured resin is harder than clay or PVC and tree roots cannot penetrate it.
Network plumbers always start with a CCTV inspection (provided as a recording or report) so you can see exactly what's being repaired. They then quote relining versus dig-and-replace side by side. In 8 out of 10 cases relining is dramatically cheaper because there's no restoration work to driveways, paving, or established gardens.
Relining work that connects to the public sewer requires the plumber to be SA Water-accredited. Network plumbers carry this endorsement in addition to PGE Act registration.
Pipe Relining Cost - questions
In most cases yes. A typical 6m reline is $2,700-$3,900. Dig-and-replace for the same length is often $4,500-$15,000+ once you add excavation, pipe materials, backfill, and restoration of driveways, paving, or established gardens. Where the pipe is under turf with no major restoration, dig-and-replace can occasionally compete on price.
Most CIPP liners carry a 50-year structural warranty. The cured resin is harder than the original clay or PVC in most cases. Tree roots cannot penetrate a cured liner.
Most clay, PVC, copper, and cast iron drains under 200mm diameter can be relined. Pipes that have fully collapsed, that have severe sags (bellies), or that are damaged beyond wall thickness loss may need spot replacement instead. Your matched plumber will tell you after the diagnostic CCTV.
Most domestic jobs complete in one day: CCTV in the morning, liner install by midday, curing in the afternoon, post-job CCTV by 5pm. Larger jobs (long sewer mains, multiple branches) may run 2-3 days.
Yes - relining is an approved repair method under the SA Plumbing Code and AS 4956. Network plumbers provide the CCTV before-and-after recordings as compliance evidence.
