In the event you have a drain that is still working but draining slowly, reach for your plunger first. Most small clogs can be quickly cleared with this handy tool every home should have.
Use a plunger with a large rubber suction cup with a handle. Cup it tightly over the drain and plunge vigorously several times (the key to this working properly is to ensure you have a good seal). If you have a double sink, make sure you seal the other drain as well.
If that doesn’t do the trick, or the problem comes back, it’s time to call the drain cleaning specialists.
