Few drains block instantly. Since the pipe narrows slowly, the property shows tell-tale signs before drainage stops completely. Catching those signs early makes the difference between a routine callout and a flooded kitchen.
Slow draining is the first clue
A sink, bath, or shower taking longer to empty than before usually means a partial blockage. It's easy to get used to a slow drain and stop noticing it. Still, it helps to time how long a full sink takes to empty. Compare that to a few weeks ago.
Gurgling after you flush or empty a sink
A gurgling sound from a nearby drain, plughole, or toilet often means trapped air. Water pushes that air around the pipe run as it tries to pass a partial obstruction. This alone isn't an emergency, yet it's a reliable early warning sign.
A smell that won't go away
Standing water or trapped debris starts to smell within days. Cleaning around the plughole won't fix a smell that keeps coming back. When that happens, the source sits inside the pipe, not on the surface.
The toilet behaves differently
A toilet that flushes slowly often signals a blockage further down the system. The same applies if the water rises higher than usual before settling. If more than one toilet shows this, the shared drainage likely has the problem. It's probably not just one fixture.
More than one fixture affected at once
A single slow sink is probably local to that one pipe run. Several fixtures failing at once, such as a downstairs toilet and an upstairs bath, share one drain. That shared drain usually needs professional equipment, not a plunger.
Damp patches with no obvious cause
A damp wall or floor patch can mean pressure is escaping from a blocked or cracked pipe. This can happen even with no leak visible above ground. Left alone, it can cause real structural damage. Because of that, it's worth getting it checked rather than simply painting over it.
When it stops being a "watch it" situation
Water coming back up through a drain or toilet means the blockage is complete, not just slow. At that point, DIY methods won't help, and professional drain unblocking is the right call.
If several of these signs show up together, book a CCTV drain survey. It shows exactly where the blockage sits and what's causing it, instead of leaving you guessing. For anything backed up or flooding, our emergency drain services cover Exeter and the surrounding area 24/7. If it's a burst pipe instead of a blockage, our emergency plumber service handles that too. Not sure which one you're dealing with?
