A blocked drain can be a major inconvenience in the home, as slow-flowing water in sinks and bathroom areas can make it more difficult to carry out everyday household tasks. Householders can clear drains using drain cleaners or with a manual clean. If the problem is more serious, they may need to contact a plumber.

Off-the-shelf drain cleaners

Off-the-shelf drain cleaners can be highly effective. Always handle with care when using these by following the manufacturer’s instructions and taking measures to protect the skin, lungs and eyes.

Homemade drain cleaners

Householders with blocked drains can make their own natural drain cleaner. Pour ¾ cup of baking soda down the drain, and follow with ½ cup of vinegar. Leave for at least 30 minutes before turning on the tap.

Manual cleaning

A manual clean can remove any stubborn objects stuck in the drain. Remove the trap under the sink and clean out the piping.

If drain cleaners and manual cleaning do not do the job, it may be time to contact a plumber, who can check if the problem is more serious or further down the line.
