A blocked drain usually becomes an emergency when wastewater is coming back into the property, an outside drain is overflowing, or you can no longer use a toilet or the main drains at all. A drain that is simply slow can often wait for a planned visit, but one that is backing up or overflowing needs prompt attention.
The deciding factor is usually the risk to health and the property, not just the blockage itself. Knowing the warning signs can help you decide how quickly to act.
Signs a Blockage Needs Urgent Attention
Some situations are more serious than others. A blockage may need dealing with quickly if:
- Wastewater or sewage is rising through a toilet, shower, bath or floor drain
- An outside drain, gully or inspection chamber is overflowing
- Using one fixture makes water appear in another
- The only toilet in the property cannot be used
- Wastewater is spreading towards rooms, walls or a neighbouring property
These signs suggest the drain beyond the fixtures is badly restricted. They do not show exactly where the blockage is, which may need checking.
When It Can Usually Wait
If one sink or basin is slow but still drains, other fixtures work normally and nothing is backing up, the problem is usually less urgent. A slow drain can still get worse, so it is worth arranging a check rather than leaving it for weeks.
Smells on their own, or a single gurgling plughole, are not usually an emergency, although they can be early signs that the drain is starting to struggle.
Your situation matters too. A blocked drain in a busy family home, a care setting or a business that serves the public may be more pressing than the same problem in a property that is empty for a few days.
What to Do Straight Away
If wastewater is backing up, stop using taps, toilets, showers and appliances that drain into the affected system. Running more water can push more waste back into the property.
Avoid direct contact with wastewater, keep children and pets away and wash your hands thoroughly after any contact. Keep clear of any water near sockets or electrical equipment. Do not lift heavy drain covers or reach into a drain or chamber.
If neighbours are affected too, or the problem seems to come from the public sewer, your sewerage company may need to be told.
Getting Help
When describing the problem, say which fixtures are affected, whether water is coming back up and whether anything outside is overflowing. This helps judge how urgent it is.
