Blocked drains in Como
Updated October 2026
Como is one of the oldest corners of the Shire. The village grew up around the railway in the late 1800s, and the suburb still carries that history in its cottages, its steep streets running down to the Georges River and its ageing underground pipework. If any suburb in the Shire was built for blocked drains, it is this one. Shire Blocked Drains connects you with licensed local drain plumbers who work Como and the surrounding river suburbs every week.
Why Como drains block
Age is the big one. Como's older homes, from Federation-era cottages through to mid-century brick, commonly sit on original earthenware sewer lines. Clay pipe this old has had a century or most of one to crack, settle and open at the joins, and the suburb's thick tree cover exploits every gap. Root intrusion in old clay is the single most common blockage cause the licensed drain plumbers we work with see in Como.
Terrain compounds it. The suburb falls steeply from Como West down to the river and Scylla Bay, so pipe runs are long, falls are uneven where ground has moved, and stormwater travels fast. Blocked gullies and pits overflowing across steep driveways after a southerly buster is a familiar Como scene.
Newer townhouses and rebuilds near the station have modern PVC, but many still connect through older shared or boundary lines, so even new homes inherit old problems.
What clearing a blocked drain involves
With pipes this old, guessing is expensive. The plumbers we refer start with a CCTV drain camera inspection to see the pipe's actual condition, then clear the line with jet blasting.
A standard clear typically costs $150 to $400. Heavy tree roots in drains or collapsed clay cost more, and where a century-old line is failing along its length, pipe relining renews it without digging up the garden. Sewage backing up indoors is an emergency blocked drain and treated as urgent.
Frequently asked questions
Our cottage is nearly 100 years old. Should we replace the drains entirely?
Not necessarily. Plenty of old clay lines still have sound sections. A camera inspection maps exactly which parts are failing, and relining just those sections is often far cheaper than full replacement.
Why does our drain block every winter?
Tree roots grow towards warm, nutrient-rich sewer water, and growth that started in autumn often closes the line over winter. An annual jet blast or a root treatment breaks the cycle.
Do the plumbers also cover the suburbs next door?
Yes. Jannali, Bonnet Bay and Sutherland are part of the same service area.
