Place a bucket underneath. Unscrew the curved trap beneath the sink (hand-tight nuts usually need no tools). Clean out the sludge, food particles, or tiny utensil that fell in. Reassemble tightly.
Feed a ¼‑inch snake through the drain opening past the trap. Crank it to break up or retrieve the clog. For garbage disposal clogs, use the hex key (Allen wrench) in the bottom of the unit to manually rotate the blades. how to unclog double sink
Liquid chemical drain cleaners can damage old metal pipes and are ineffective against full clogs. Also, never pour boiling water directly into a porcelain sink—run the hot tap first to avoid cracking. Place a bucket underneath
A double kitchen sink is a convenient setup—until water starts backing up into both basins. Because the two sinks share a common drainpipe, a clog often reveals itself when you run the disposal or wash dishes on one side, and dirty water rises through the other. Before you reach for harsh chemicals, try these proven steps. Reassemble tightly
A double sink requires sealing the opposite drain to create proper suction. Use a wet rag or a second plunger pressed firmly over the unused drain. Then plunge the clogged side vigorously for 20–30 seconds. The trapped air forces pressure through the shared pipe.
If water still won’t drain after these steps, the clog may be in the main stack. That’s when a professional with a hydro-jet or camera inspection is worth the call. But in most cases, a rag, a plunger, and a little elbow grease are all you need to reclaim your double sink.
