How to Unblock a Sink

Sinks can get blocked for a number of reasons. If your kitchen sink is blocked, it’s probably because of small bits of food going down the plughole, whereas if your bathroom sink is blocked it could be due to a build-up of hair. Here are several ways to unblock your sink.

Method One: Use a Plunger

The first thing you should try when you have a blocked sink is using a plunger. First, make sure there’s nothing stuck in the plughole. Remove any hairs or bits of food that might be stuck there.

There needs to be some water covering the plughole for a plunger to work, so unless the sink is completely blocked you may need to run the tap at the same time.

If you don’t have a plunger, you can do this with your hand. If you’re using your hand, you should wear rubber gloves for hygiene purposes. You should also order a good plunger like the Monument 1459W Master Plunger Sink and Waste Pipe Unblocker for next time.

Push the plunger (or your hand) down onto the plughole and lift it up again several times. If you start to see bits of food or other debris come out of the plughole, try to remove them from the sink and put them in the bin.

Method Two: Remove the ‘U bend’

If plunging the sink didn’t work, they may be a build-up of debris in the ‘U bend’. If you think this might be the case, you can carefully unscrew and remove the U bend to clean it out. First, put a bucket under the U bend to collect any water that might be stuck in it. Gently unscrew it and remove it, and clean out any gunk and put it in the bin.

A sink strainer can help prevent your sink from blocking.

Method Three: Use a Sink Unblocker

Another way to unblock your sink is to use a special sink-unblocking chemical. This could be a liquid like Domestos Sink and Pipe Unblocker or dried flakes like Duzzit Drain Away.

Prevention is better than cure

A blocked sink can be prevented by using a sink strainer. This is a small sieve-like piece of metal or plastic that goes over the plughole and prevents debris from going down the sink.
