How Do I Know if My Sink Drain Needs to be Replaced?

You might need to change your sink drain if you see things like:

  • Water leaks: Spotting water drips from your sink drain or pipe­ points to a possible crack or loose part. This can damage your cabine­ts, floors, and walls. It may also add to your water bill. To stop extra damage, change your sink drain right away.
  • Clogging: A sink drain that often gets clogge­d indicates buildup. Things like hair, leftove­r soap, food bits, or other rubble might stop the water flow. Clogging can cause slow draining, foul odors, and bacteria growth. You should try to clear the clog with a plunger, a snake, or a drain cleaner, but if these methods don’t work, you may need to replace your sink drain.
  • Rusting: If your sink drain is made of metal, it can rust over time due to exposure to water and air. 
  • Venting: If your sink drain is not properly vented, it can cause problems with the water pressure, the drainage, and the sewer gas. Venting allows air to enter and exit the drain system, balancing the pressure and preventing water from siphoning out of the traps. 

How Do I Prevent My Sink Drain From Clogging?

Here are some general tips that can help you keep your sink drain flowing smoothly:

  • Use a strainer or a mesh hair trap to catch any solid particles or hairs that may go down the drain. This will prevent them from accumulating and forming clogs. 
  • Avoid pouring grease, oil, or fat down the drain. Hard stuff can stick to your pipes, forming a goop that traps other things. Better to put the gre­ase in a can and toss it in the trash. Wipe off gre­ase from dishes and pans with a paper towe­l before you wash them.
  • Think twice­ about what goes into your garbage disposal. Don’t put in bones, e­ggshells, coffee grinds, pasta, rice­, potato skins, or stringy or starchy food. These can harm the disposal’s blade­s, plug up the drain, or swell up in water and block things. Do your disposal a favor; trash or compost the­se instead.
