   Regular drainage pipe maintenance is crucial for every homeowner. Flushing pipes prevents minor clogs from becoming major blockages. Baking soda and vinegar can clear more stubborn obstructions without using harsh chemicals that risk eroding pipes. If a clog persists despite your efforts, calling a professional plumber is wise. Their specialized tools can clear blockages without damaging the system. Although hiring a technician costs money upfront, it prevents exorbitant repairs down the line. An ounce of prevention is worth a pound of cure when maintaining drains.

4. 4

   Flush the drain with hot water from the faucet. After the hot water has drained, turn on your faucet on the highest heat. If the drain is clogged or slow, you may have to repeat the process to remove bigger grease obstructions and unclog it.^[4]

Clean off the bottom of the stopper and wipe down the area if there is any gunk or hair that you've pulled up.^[11]
