Collapsed Sewer Repair, CCTV Drain Inspection & Plumbing Repairs in Northbridge NSW 2063
Diagnosis: Investigating the Broken Line
Investigation at a Northbridge NSW 2063 property revealed a broken and collapsed sewer line in the front garden. Unlike a simple blockage, a collapsed pipe breaks structurally, stopping wastewater flow and collecting debris repeatedly.
-
Targeted Location: Plumbers located and marked the damage in the front garden, limiting excavation to roughly one metre instead of tearing up the entire yard.
-
Drain Jetting & Camera Work: High-pressure water jetting cleared debris out of the sewer and stormwater lines. A CCTV drain camera was then run through the pipes to inspect internal damage from underground.
-
Action Plan: Because the pipe was physically collapsed, clearing it repeatedly was insufficient; full sewer pipe repair was required.
The Solution: Precision Replacement & Protection
The strategy focused on fixing the damaged section while preserving nearby working pipes:
-
Targeted Excavation: Plumbers excavated the marked 1-metre section and replaced the failed pipe with new PVC drainage.
-
New Inspection Opening: A new ground-level inspection opening was added so plumbers can easily perform future maintenance, drain cleaning, or CCTV inspections without digging.
-
Stormwater Extension: Installed a new section of PVC pipe running toward the stormwater drain near the rock wall.
-
Concrete Encasement: Encased the transition connections between new PVC and old pipes in concrete for structural strength and protection.
-
Pipe Bedding & Restoration: Surrounded the new underground pipework with 8–10mm blue metal aggregate to absorb ground pressure, then backfilled, raked, and restored the garden bed.
High-Pressure Jetting & Final CCTV Inspection
-
Cleared both sewer and stormwater drainage using high-pressure water jetting to remove stubborn material.
-
Ran a post-repair CCTV drain inspection across the accessible system to confirm open pathways and verify there were no hidden defects.
Additional Bathroom Plumbing Repairs
-
Toilet Installation: Removed the existing toilet pan and installed a customer-supplied toilet using new fittings.
-
Tap Service: Serviced the hot and cold bath taps to fix wear and tear and improve operation.
-
Site Cleanup: Tested and commissioned all work before removing all trade rubbish from the site.
Long-Term Value
Clearing a collapsed sewer only offers temporary relief. By replacing the specific 1-metre failed section, the property got a permanent structural fix while avoiding the high costs of replacing the entire line. The addition of a ground-level inspection opening and a full system CCTV check ensures easy, lower-cost maintenance in the future.
