Drains rarely fail without warning. If you notice any of the signs below, get them checked before a small clog becomes an overflow.
Slow draining: water that lingers in sinks, tubs, or showers usually means buildup is narrowing the pipe.
Gurgling sounds: air pushed through a partially blocked line often makes noise as water moves.
Recurring odors: a persistent smell from a drain points to trapped debris or grease.
Multiple fixtures backing up: if the toilet gurgles when you run the washer, the main line may be blocked.
Frequent clogs: the same drain clogging every few weeks means the real blockage is further down the line.
