Kallangur is one of the older towns along Anzac Avenue, and it shows in the housing: 1970s and 80s brick and timber, a scattering of larger semi-rural blocks on the edges, and a steady layer of newer unit and townhouse infill near the main road and the rail line. Moreton Bay Blocked Drains is a local referral service, connecting Kallangur residents with QBCC-licensed local drain plumbers we work with.
Why Kallangur drains block
Kallangur is old enough that plenty of homes still run jointed clay sewer lines. Those joints open slightly as the ground moves, leak moisture into the soil, and effectively advertise themselves to every tree within reach. The mature trees in the established streets have had decades to respond.
The newer infill brings the opposite problem. Townhouses and duplexes share drainage between several households, so grease and wipes from several kitchens and bathrooms build up in one line, and the lowest dwelling is the one that notices.
On the larger blocks towards the edges, the private sewer run from the house to the connection point can be long. Long lines have more joints and more bends, and a blockage at the far end backs water the whole way up to the house.
What clearing a blocked drain involves
The licensed drain plumbers we work with usually start with a CCTV drain camera on older lines, because guessing at the cause of a blockage in clay pipe is expensive. Jet blasting with a root-cutting nozzle shears roots off at the pipe wall rather than punching a channel through them. Where the camera finds a broken pipe, pipe relining repairs it without excavating the yard.
A standard clear typically costs $150 to $400. Root clearing typically costs $250 to $600. A camera inspection runs $249 to $600, or $350 to $900 combined with jetting. Relining typically costs $3,000 to $8,000 or more. Every job is quoted first.
Frequently asked questions
My drain blocks about every eighteen months. Why?
That pattern is almost always roots in a clay line. Each clear buys time but the roots grow back. A camera inspection shows how bad the pipe is, and relining the damaged section ends the cycle.
Who is responsible for the sewer main in the street?
Unitywater owns and maintains the sewer mains. You are responsible for the private line from your house to the point of connection. A camera with a locator shows which side the fault sits on.
We are in a townhouse. Who sorts out a shared line?
Blockages in common property drainage are generally the body corporate's responsibility, while a blockage in your own fixtures is usually yours. Let the body corporate manager know as well as requesting a quote.
