What are the early signs of a blocked Drain


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.
Foul smells are a real giveaway for a blocked drain. The bad smell may start before any visual symptoms emerge.
Unusual noises from drains, plug holes or toilet flushes are created by displaced trapped air because of a drain blockage.
