Why Blocked Drains Are So Common in Hobart's Older Suburbs

If you live in an older part of Hobart — Battery Point, North Hobart, New Town, or Sandy Bay — chances are you've dealt with a blocked drain at some point. There are real reasons why blocked drains are more common here than in newer areas.

The age of Hobart's pipes

Hobart has some of the oldest housing stock in Australia. Many homes in the inner suburbs were built in the 1800s and early 1900s using earthenware clay pipes. Those pipes are now well over a century old. Clay pipes crack, shift with the soil, and develop joints that tree roots can penetrate easily. Even homes from the 1950s and 60s were built with materials now at or past the end of their working life.

Tree roots are the main culprit

Hobart's residential streets have mature trees with extensive root systems. Roots are attracted to any moisture source, and a slightly leaking pipe joint is an open invitation. Once a root finds its way in, it keeps growing. Left unchecked, roots can completely block a 100mm sewer line within a year or two.

What to do about it

High-pressure water jetting combined with a CCTV drain inspection is the right approach. Jetting clears the blockage. The camera shows what caused it — whether it's roots, a collapsed section, or heavy grease buildup in the pipe. If it's roots, you need to know whether the pipe is structurally sound (regular clearing may be the practical answer) or cracked (drain relining is worth considering as a permanent fix). If you're dealing with regular blockages in an older Hobart home, give us a call.

Frequently Asked Questions

Why do drains block so often in older Hobart homes?

Older homes in Hobart commonly use clay or cast iron pipes that crack and shift over decades. Tree roots exploit these cracks, and pipe joints accumulate grease, hair and debris much faster than modern PVC systems.

How much does it cost to clear a blocked drain in Hobart?

A standard blocked drain clearance in Hobart typically costs between 50 and 50 depending on access and severity. A CCTV camera inspection to locate the blockage adds another 00–00.

Can I clear a blocked drain myself in Hobart?

Minor blockages near the drain opening can sometimes be cleared with a plunger or drain snake. However, if the blockage is deep, recurring, or involves tree roots, call a licensed Hobart plumber to avoid damaging the pipes.
