Common Signs of a Blocked Drain
Some blockages develop gradually, while others can stop a drain from flowing with little warning. Recognising the early signs can help you deal with the problem before water begins backing up or overflowing.
Common signs include:
- sinks, showers or floor drains draining slowly
- gurgling or bubbling sounds from drains
- unpleasant smells coming from sinks or drains
- toilets that are slow to flush
- water backing up through another fixture
- outdoor drains overflowing
- more than one drain becoming blocked
- the same drain repeatedly blocking
If several of these problems are happening at the same time, the blockage may be located deeper within the drainage line.
