Summer in Adelaide has a way of making you fall into a false sense of security. Blue skies for days…dry heat…then suddenly a proper downpour. The kind that hits hard, fills gutters in minutes and leaves the yard looking like a small lake. Most homeowners breathe a sigh of relief once the storm passes. At aba PLUMBING + GAS we’ve learned over the years that the real issues often show up after the weather clears.

Not always dramatically as sometimes it’s subtle. As a homeowner take a walk around your property and check for puddles. Do you see any sitting near drains long after the rain has stopped? Overflow marks around grates? Bits of mulch, leaves or debris jammed into stormwater pits? That tells you the system was under pressure.

Adelaide’s summer storms dump a lot of water in a short time. If your stormwater drains were already partially blocked, that surge can push them to the limit. And once that happens the blockage doesn’t magically disappear when the sun comes out.

Clear what you can see. But if water struggled to move during the storm, it’s worth paying attention.

Blocked Drains Adelaide – Listen to What Your Plumbing Is Telling You

Do not overlook this part as after heavy rain, if your toilet gurgles slightly or your shower drains slower than usual, that can be connected to external drainage pressure. It doesn’t mean disaster, but it does mean something shifted. Stormwater systems and sewer drains don’t operate in isolation. When one struggles, the other can show symptoms.

• Check for Sinking or Soft Ground: If sections of your yard feel unusually soft, or there’s a small dip forming near where pipes run underground, soil may have washed away around a drain line. Over time, that can stress the pipe itself.

Tree roots are another issue. After heavy rain, roots chase moisture aggressively. Tiny cracks in older pipes, especially in established Adelaide suburbs, become easy entry points. You won’t see it straight away. But give it a few weeks, and blockages start forming.

• Keep an Eye (and Nose) Out for Odours: Sewer smells after storms aren’t normal. Even faint ones and heavy rainfall can expose weaknesses in venting systems or highlight cracked pipework. If you catch a whiff outside near drains, or worse, inside the home, don’t ignore it.

• Gutters and Downpipes Do More Than You Think: Storm damage isn’t always underground. If gutters overflowed or downpipes struggled to cope, that excess water had to go somewhere and that’s how it ends up saturating areas around foundations or pushing more load into stormwater drains.

Check for loose joints, sagging sections or water staining on external walls. These are small clues that your drainage system was overwhelmed.

When It’s Time to Call a Professional Drain Plumber in Adelaide 

Not every storm causes lasting damage. But if you notice repeated slow drainage, pooling water that lingers, strange noises or smells that weren’t there before, it’s worth having it checked properly. Modern drain inspections aren’t guesswork anymore. A CCTV drain camera inspection can show exactly what’s happening inside the pipe and take a good look at roots, debris, cracks or collapses. It’s straightforward and far less disruptive than people expect. Our drain plumbers at aba PLUMBING + GAS always tell homeowners that if something feels off after wild weather, trust that instinct. You live there. You notice changes.

Adelaide’s summer storms are intense, but short. The damage they leave behind isn’t always obvious but small signs matter, slow drains matter and even that faint gurgle matters. And it’s always easier to fix a minor problem in calm weather than a major one during the next downpour.
