Drain Replacement Experts Across Adelaide Metro
Some drains fail past what cleaning can fix, and drain replacement is the permanent answer: digging out the broken underground pipe and laying new line where a sewer or stormwater drain sits collapsed or root-shattered.
When a Drain Needs Replacing Not Cleaning
Wondering whether a pipe can be cleared again or has reached the end of its life? These faults demand replacement:
-
Repeated Blockages
Drains that clog again within weeks of every clear have lost shape or fall underground, so jetting no longer helps and replacement becomes the only lasting answer for Adelaide homes.
-
Collapsed Pipe
Collapsed sections cave inward and block flow completely, leaving wastewater nowhere to go, which means excavation and a fresh length of pipe are the only way to restore proper drainage.
-
Tree-Root Damage
Invasive roots from established gardens crack and lift old joints as they hunt for moisture, and once a pipe is shattered this way, cutting the roots only delays full replacement.
-
Ageing Earthenware
Older earthenware and clay drain lines, where a property still has them, tend to crack at the joints as they age, and a modern PVC replacement is the sensible upgrade.
-
Corrosion & Cracks
Cast-iron and steel drains rust from the inside until walls thin and split, so when corrosion has weakened a whole run, patching fails and full replacement protects your Adelaide home.
-
Poor Pipe Falls
Pipes laid with too little grade let waste and grit settle instead of draining away, which leaves a drain that blocks repeatedly despite cleaning and needs relaying at correct fall.
Don't ignore these
Signs Your Drain Is Failing Underground
Spotting trouble early keeps a small excavation from becoming a major dig, so watch your property for these warning signs:
Sinkholes or Wet Patches
Soft, sunken ground or a patch of lawn staying wet in dry weather usually means a cracked drain is leaking beneath it, slowly washing soil away and undermining nearby paths.
Sewage Smells
Persistent sewer odour around the yard or drains signals waste escaping through a broken pipe instead of reaching the main, a health risk that worsens the longer it is ignored.
Slow Drainage Everywhere
Multiple fixtures draining slowly at once, sinks, showers and toilets together, points to a failing main line rather than one blocked branch, which almost always calls for excavation and replacement.
Should You Reline or Replace Your Drain
Not every failed drain needs digging up, so understanding the three options helps you choose the right fix for yours:
-
No-Dig Pipe Relining
Where a pipe is cracked but still structurally sound, our no-dig pipe relining cures a new liner inside the old one, avoiding excavation and restoring flow without disturbing your garden.
-
Full Excavation
Badly collapsed, corroded or root-shattered drains leave no liner to work with, which means digging down to the damaged run, removing it entirely and laying new pipe to correct grade.
-
Partial Repair
When only a short length has failed, we replace that single section and rejoin it to the sound pipe either side, a targeted fix that keeps excavation and cost minimal.
No surprises, start to finish
How Our Plumbers Work
Dig Once, Dig Right
Every replacement follows the same tidy sequence, so you always know what happens next and when your yard is restored:
- 1
CCTV Inspection
First we run a CCTV drain camera through the line to pinpoint exactly where and why it has broken, meaning you replace only the length that has truly failed underground.
- 2
Locate & Plan
Before any digging, our team marks the pipe run and nearby services, plans the neatest access route and confirms the scope with you, keeping surprises and disruption to the minimum.
- 3
Excavate
Using compact machinery and careful hand digging, we open a tidy trench straight to the failed section, protecting lawn, paving and nearby services as the old drain finally lifts out.
- 4
Replace & Backfill
New PVC or approved pipe is laid to correct fall, and our plumbers at Exceed Plumbing bed and backfill it in compacted layers, giving a drain built to Australian standards.
- 5
Test & Restore
Once flow is tested and the joins pass, we reinstate soil, turf or paving and leave the site clean, with the only sign of our work a freely running drain.
Replacing Adelaide Sewer and Stormwater Drains
One fact catches many Adelaide homeowners out: the drain that fails on your property may not be yours to replace:
Stormwater Drains
Stormwater drains move roof and surface run-off away from footings, and when they crack or block, our blocked stormwater crews replace collapsed lengths to stop pooling and protect your foundations.
Downpipes & Soakwells
Downpipe connections and soakwells fail quietly as they silt up or crack, and replacing them properly keeps stormwater draining away from the home instead of pooling around your house footings.
Council & SA Water
SA Water owns the sewer mains beyond your boundary, so its network is its responsibility while your drains are yours, and we replace and sign off everything on your side.

Drain Replacement Adelaide Frequently Asked Questions
Here are the questions Adelaide homeowners ask most before a drain replacement, answered plainly so you know what to expect:
How do I know if my drain needs replacing?+
Your drain likely needs replacing when it blocks repeatedly despite cleaning, or when a CCTV camera shows a collapsed, root-shattered or badly corroded pipe that a liner can no longer restore.
Can a broken drain be relined instead of replaced?+
Yes, if enough of the original pipe survives, relining seals a new liner inside it with no digging; a fully collapsed or missing section, however, must be excavated and replaced.
How long does drain replacement take?+
Most residential drain replacements take one to two days, depending on depth, access and the length of pipe involved; our team confirms a realistic timeframe once the CCTV inspection is done.
Do you replace both sewer and stormwater drains?+
Yes, our plumbers at Exceed Plumbing replace sewer lines, stormwater drains, downpipe connections and soakwells across Adelaide, handling everything on your side of the boundary while SA Water manages its own mains.
Will you restore my yard after excavation?+
Yes, once flow is tested and joins pass, we backfill in compacted layers and reinstate soil, turf or paving, leaving your yard tidy with the only sign a freely running drain.
How quickly can you assess a failing drain in Adelaide?+
Our emergency response across Adelaide aims for within the hour, so a failing or overflowing drain can usually be camera-assessed the same day, with a fixed replacement quote provided before any work begins.
