Elanora Heights sits on the high ground above Narrabeen Lagoon, with family homes mostly from the 1960s and 70s, a village shopping strip and bushland falling away on several sides toward the lagoon and Ingleside. Leafy, elevated and built in one era, it has a fairly consistent set of drain issues. Beaches Blocked Drains connects Elanora Heights residents with licensed local drain plumbers.
Why Elanora Heights drains block
Most original homes were built with earthenware or early sewer pipe that is now around fifty years old or more. Joints open over time, and the big gums in gardens and the surrounding bushland send roots into them. A drain that blocks once a year or so is a common story.
The slopes toward the lagoon are steep in places. Homes on the low side of the street may have sewer lines that run to an easement at the back, and stormwater that runs quickly downhill, collecting soil and leaves.
Leaf litter from the bush fills gutters, downpipes and pits, especially in summer and after strong winds.
How the plumbers we refer usually work
A CCTV drain camera traces the line and shows root entry points and pipe condition, which is useful when the sewer runs down a slope to a rear easement. Jet blasting clears roots and debris. If the pipe is cracked, pipe relining seals it from inside without excavating a bushy slope.
What it costs
A standard clear typically runs $150 to $400. Tree roots in drains clearing typically runs $250 to $600. Relining typically starts around $3,000. The quote comes before the work.
Frequently asked questions
Our sewer runs down the hill to the back of the block. Is that normal?
Yes, on the low side of a street the main often runs through rear easements. The line from your house to that main is yours to maintain.
How can we stop roots coming back?
If the pipe is sound, scheduled clearing can manage roots. If joints are cracked, relining seals them and is the long-term fix.
Should we clean our gutters more often near the bush?
Bush-edge homes usually need it more often. Gutter guards and leaf diverters reduce how much reaches the stormwater pits.
