How bleach can be used to unclog a drain

drains

If you find that water is draining slowly from your sink or bathtub, household bleach is a very good substance for dissolving the hair, grease and muck likely to be causing the blockage. Remember, however, that bleach is an irritant and can be hazardous if it comes into contact with the skin. For this reason, although unclogging a drain may not seem like a major operation, it shouldn’t be approached without due consideration for health and safety.

With this in mind, we suggest the following:

  • Wear a good pair of rubber gloves to stop the bleach making contact with your hands.
  • Consider wearing eye protection too. We know this might seem a bit over-cautionary for such a comparatively small task but, especially if you use a plunger, splashes can be harmful.
  • Don’t lean directly over the drain while using bleach.
  • If any bleach makes contact with your skin or eyes, seek medical advice immediately.

Once you’re appropriately kitted up, carefully follow these steps:

Step one

Remove the drain cover if possible and pour the bleach down. Different bleaches come in varying strengths so rather than provide a definitive amount of bleach to use, we suggest reading the guidelines on the label and using them as the basis for your decision.

Step two

Now leave the drain for about 20 minutes and allow the bleach to work its way through the matter causing the blockage.

Step three

Run plenty of boiling water down the drain to rinse it out and clear the bleach and dissolved residue still lingering there.

Step four

If you still find that drainage is slow, use a wire hanger to hook out whatever might be clogging it up.

If all else fails…

Failing that, it’s possible that your drain might need professional attention, so make an appointment with an expert.
