Slow draining water
If water drains slowly, water levels are too high or too low, or water comes up in a sink or bath, you have a blocked drain.
Bad smells
Foul smells are a real giveaway for a blocked drain. The bad smell may start before any visual symptoms emerge.
Gurgling noises
Unusual noises from drains, plug holes or toilet flushes are created by displaced trapped air because of a drain blockage.
