Warning signs of a developing drain problem
Slow-draining sinks, gurgling toilets and unpleasant odors are more than minor inconveniences. They often begin with a buildup of grease, hair and soap scum that narrows the pipe and can progress to a complete blockage.
Left alone, a partial clog can lead to backups and water damage. Note whether one fixture or several are affected. A single slow sink often points to that drain, while several fixtures slowing together may point further down the line.
