Blocked drains
Help with blocked, slow, overflowing, or repeatedly troublesome drains.

Blocked drains are one of the most common plumbing call-outs across Gauteng. Whether it is a slow kitchen sink, a shower that backs up, or an outside drain overflowing after rain, the cause — and the correct fix — depends on where the blockage sits and what is causing it. Surface-level clearing with a plunger or cleaning the trap under a basin sometimes works for a simple local blockage. But when water backs up across multiple fixtures, smells persist, or the same drain keeps blocking, the problem is usually deeper in the pipework.
Common causes of blocked drains in Gauteng homes include grease and fat build-up in kitchen waste pipes, hair and soap residue in bathroom lines, tree root intrusion into older sewer connections, foreign objects flushed down toilets, and collapsed or poorly installed pipe sections. Pouring harsh chemical drain cleaners into a blocked drain is rarely the right answer — they can damage pipes, create safety risks for the plumber who eventually opens the line, and often fail on solid blockages.
I Plumb provides blocked drain plumbing across Gauteng with the right equipment for the job — whether it needs drain rodding, high-pressure jetting, or in more serious cases, excavation and pipe repair. The goal is to clear the blockage properly and identify whether the cause is a once-off problem or something that will keep happening unless the underlying issue is fixed.

Questions
For a minor sink or shower blockage, you can try removing and cleaning the trap under the basin and using a plunger on the fixture. Avoid harsh chemical drain cleaners — they can damage your pipes and create safety risks. If the blockage returns, affects multiple fixtures, or involves sewage, stop and call a plumber. Repeated blockages usually mean the cause is deeper in the line and needs professional equipment to clear properly.
Yes. Recurring blockages often indicate a persistent issue like tree roots growing into pipe joints, collapsed or misaligned pipe sections, heavy grease accumulation, or incorrect pipe falls that allow debris to settle. A once-off blockage can sometimes be cleared and forgotten, but if the same drain blocks again within weeks or months, there is an underlying cause that needs investigation. Fixing the root cause is almost always cheaper than repeated emergency call-outs.
