A clogged sink drain is a pain, but thankfully is usually quite easy to fix.  When your double-sided sink is clogged, plunging should be your first course of action. The pressure formed by plunging a sink, forces the clog to move, allowing water to freely flow through your pipes.

Plunging a double basin sink is easy when you follow these simple steps:

1. Start by ‘plugging’  or ‘blocking up’ one side of the sink. You can use a simple rag to block up one side of the sink. If the sink has a drain stopped you will want to start by removing it. If your kitchen utilizes a garbage  disposal, block the side opposite the disposal.
2. Position the plunger directly over the open drain, grab the plunger with both hands,  and make even plunges in an up and down motion. The upward motion of the plunger is just as important as the downward motion.  If you have trouble getting the plunger cup  to seal with the sink, you can add petroleum jelly around the cup.  Repeat the up and down motion rapidly and forcefully about a dozen times.
3. Remove the plunger by quickly breaking the seal. Check to see if the water drains; if not, repeat the process.
4. Once water drains, unplug the opposite drain, and  run hot water through the sink for around 90 seconds to help clear any left over debris.
5. Congratulate yourself for your DIY appliance fix.

Further tips on clogged double-sided sink drains:

• If the plunging process is not able to unclog the sink, the drain may need to be snaked.
• Drain cleaners can help unclog drains but contain caustic chemicals that can splash up on the face or arms when plunging. Never use drain cleaner before plunging a sink.
