Blocked Drains Unley

Warning signs of a blocked drain in Unley

The earlier you call, the cheaper the fix. Watch for:

• Bad smells from sinks, drains or the back yard
• Slow-draining sinks, basins, baths and showers
• Gurgling sounds from toilets or floor wastes when a tap runs
• Water backing up in the shower when the washing machine drains
• Wet patches in the lawn near the sewer inspection point
• More than one fixture blocked at once (a sign the main sewer line is the problem)

If wastewater is pushing out of the lowest drain or the overflow relief gully, that is an emergency. Call 0432 667 785 straight away.

What causes blocked drains in Unley

Unley’s older homes are full of original earthenware sewers, and the mature street trees that give the suburb its character also send roots into the pipe joints – the leading cause of the blockages we clear here. The other common culprits we clear across Unley are:

• Tree roots in the sewer line (the top cause locally)
• Wipes and sanitary products that do not break down
• Fats, oils and grease hardening in the kitchen line
• Hair and soap scum in bathroom drains
• Collapsed or cracked earthenware pipes in older Unley homes
• Foreign objects washed or dropped into the line

How we clear blocked drains in Unley

We carry hydrojet and CCTV gear on every van, so most blockages are cleared and inspected on the first visit:

• Diagnose which fixture and which line is blocked
• Clear with a high-pressure hydrojet that cuts roots and scours the pipe wall (electric eels for tight branch lines)
• Inspect with a CCTV drain camera so you see the pipe is clean and whether it is cracked or root-affected
• Recommend a repair or relining plan only if the pipe is genuinely damaged, with footage to back it
• Tidy and test the line before we leave

See our hydrojet drain cleaning and CCTV drain inspection pages for detail.

What it costs

A simple sink or basin clear is a single call-out. A main sewer clear with hydrojet and camera is more involved. Either way you get a written, fixed quote before any work starts. No callout fee in the quote, no surprises on the invoice. We also offer pensioner consideration and clear, upfront advice on whether to clear or repair.
