Signs You Have a Blocked Drain
While some drainage issues present themselves clearly, spotting early warning signs can help you prevent costly problems. Below is a guide of common indicators to look out for if you suspect a potential blockage in your house or workplace.
Water Draining Slowly
Water not going down right? If your sink, bath, or shower’s lagging, that’s usually the early sign. In the kitchen, it’s food and fat. In the bathroom? Bath muck are the usual suspects. If water’s just hanging out, it’s time to jump on it.

Unpleasant Smells
That nasty scent near the drain? That’s not just something in the air, it’s gunk building up, starting to turn. Food, grease, even sewage can get caught up. If you’re getting whiffs like that, don’t ignore it. It means a blockage is just starting, and it’s better to sort it quickly.

Gurgling Sounds From Pipes
Drains gurgling? That’s a warning. Usually means water’s pushing past something. If it sounds like a boiler, get it checked.

Water Backing Up
One of the easiest to spot indicators of a blocked drain is water rising back up. If you notice any sign of water backing up, it’s important to act quickly to prevent it from escalating.
Toilet Flushing Poorly
Toilet not clearing or taking too long? Might be a plug in the line. Wet wipes, sanitary stuff, or tissue usually to blame. Time to clear it out.
Overflowing Outdoor Drains
If you see water spilling from external drains during or after a storm, the issue may be more serious than simple surface runoff. A partial or complete underground blockage could be stopping water from flowing, causing water to back up. Left untreated, this overflow can affect your landscape and foundation. Prompt intervention is essential to avoid escalation.
Multiple Fixtures Affected at Once
If more than one fixture is sluggish, like your toilet, sink, and bath all backing up together, it’s probably not just a simple fix. When it’s in the main drain, the whole system gets hit. A quick go with a plunger won’t cut it here. You’ll want to get someone in to inspect things with a camera and use jetting gear to get things moving again.
Damp Patches or Mould
Leaks you can’t see can show up when you least expect. One day everything’s fine, then before you know it, wet walls, strange black spots, or a musty odour near the skirting board. If it doesn’t seem right, it probably is. And we are ready to fix it.
