North Narrabeen wraps around the northern shore of Narrabeen Lagoon and out to the beach and headland, with family homes, older cottages, townhouses and holiday accommodation. Water is never far away, which makes drainage something locals think about more than most. Beaches Blocked Drains is a local referral service. We connect you with licensed local drain plumbers who service North Narrabeen.
What causes blockages here
The low lagoon-side streets share Narrabeen's issues: flat ground with little fall, sandy soil and groundwater close to the surface. Older sewer lines sag and hold water, and sand settles in them. Stormwater systems can struggle in heavy rain, especially when the lagoon is high.
Toward the headland and the slopes behind, the picture changes. Older clay pipe, garden roots and steeper stormwater runs are the more common factors.
Holiday accommodation and rentals see more use, and guests do not always know what the line can handle. Wipes and sanitary items are common culprits.
How the plumbers we refer handle it
They usually start with a CCTV drain camera, because on flat ground a sagged or sand-filled section looks the same as a root blockage from above. Jet blasting clears sand, silt and roots properly. Damaged pipe can often be repaired with pipe relining without digging up a sandy yard that collapses back into any trench.
What it costs
A standard clear typically runs $150 to $400. Camera and jetting together typically run $350 to $900. Root clearing typically runs $250 to $600. You get a price before any work starts.
Frequently asked questions
Our holiday rental keeps getting blocked toilets. What helps?
A clear sign about what not to flush helps, and so does a camera inspection to make sure the line itself is sound. If it is, blockages are usually guest habits rather than the pipe.
Why does our yard stay wet after rain?
On low ground the water table is high and stormwater drains slowly. A blocked pit or line makes it worse. Clearing and jetting the private system before the wet season helps.
Is digging a bad idea in sandy soil?
Trenches in sand tend to collapse and need shoring. Relining avoids that where the pipe is a candidate.
