5 Signs Your Drain Is Blocked

A blocked drain usually starts with small warning signs before it turns into a bigger, messier problem. The earlier you spot the issue, the easier it is to fix – and the less chance there is of water damage, unpleasant smells, or a full plumbing emergency.

At Perth Plumbworks, we often find that customers notice the symptoms first, but are not sure whether it is a minor blockage or something more serious. Here are five common signs your drain may be blocked.

1. Water drains slowly

If water is taking longer than usual to disappear from your sink, shower, or basin, that is often the first sign of a blockage building up inside the pipe. Hair, soap scum, grease, food scraps, and debris can all restrict water flow over time.

2. Unpleasant smells coming from the drain

A healthy drain should not smell bad. If you notice a foul, sour, or rotten odour around your sink, shower, or outdoor drain, it may mean waste is trapped in the pipe and beginning to break down. This is a strong sign that the drain needs attention.

3. Gurgling noises

Odd bubbling or gurgling sounds after water goes down the drain usually indicate trapped air inside the pipe. This often happens when water is struggling to pass through a partial blockage.

4. Water backing up

If water rises back into the sink, shower, or toilet instead of flowing away properly, the blockage may be more advanced. In some cases, one blocked drain can also affect other fixtures in the home.

5. Repeated clogs or overflowing

If the same drain keeps blocking again and again, it usually means the problem has not been properly cleared. Temporary DIY fixes might help for a short time, but recurring clogs often point to a deeper issue in the pipework.

What to do next

If you have noticed one or more of these signs, it is best to act early. A blocked drain can worsen quickly and lead to more costly repairs if ignored.
