Like most homeowners, you’ll know that blocked drains can be a real nuisance. Not only are they a hassle to deal with, but they can also be quite expensive to fix if left untreated.

That’s why it’s important to take some simple steps to help prevent clogged drains in the first place. This blog post will give you five helpful tips to help you unblock your drains at home. Read on for more information!

What Are The Signs Of A Blocked Drain?

You may have a drainage blockage problem when you notice that:

They’re all signs that you may soon be facing a blocked drain. And then one day, boom. Your drain is blocked completely. You need to deal with it quickly or face the mess of a burst pipe.

The drain system may be blocked in the trap area (the curve), or a problem outside. Always start by removing the excess hair and gunk built up at the surface of the drain. Then try any or all of the following:

1. Clean It Out With A Coat Hanger Or Drain Snakes

Take a wire coat hanger and straighten it out best, then bend one end to create a small hook. Push that past the drain cover and start fishing. You should be able to get all sorts of hair and nasty stuff out of the clogged drain.

Remember, you need to pull gunk out, not push it further when you’ve got as much out as possible; flush with hot water, which should clear things up nicely. You can also use a DIY drain snake (drain auger) for drain blockage, which you will find at your local hardware store.

2. Flush With Boiling Hot Water

Pour boiling water down the drain slowly in two to three stages, allowing the hot water system to work for several seconds between each pour. This is usually the easiest and quickest way to unclog a drain. If you are doing this for a drain clog in your sink, ensure you have a bucket underneath for any excess water flow.

3. Use A Plunger

If you haven’t resorted to tipping caustic drain cleaners down to clear your dr5ain blockage, you can try to fix your clog with a plunger. This handy tool can break up clogs quickly and easily in your toilet, sink or shower drain. You may need to have several goes at it to correct the problem.

  1. Start by filling your drain until enough water covers the plunger cup completely. If you are plunging a double sink, plug in the other sink.
  2. Place the toilet plunger into the water, letting out all the air in the cup. The plunger will only work when the cup is filled with water.
  3. Create a seal by pressing the cup firmly against the sink or toilet.
  4. Plunge rapidly. If you feel slight resistance or hear water sloshing around and you are plunging a double sink, check to ensure the second sink is plugged.
  5. Once you have loosened the clog, flush the drain with hot water.

4. Try Baking Soda And Vinegar

If plunging does not solve your problem, mix ½ a cup of vinegar with a handful of baking soda and pour it down the drain. Follow this with several cups of boiling water. Let this sit overnight and flush with more water in the morning.

5. Use a Caustic Drain Cleaner

Caustic soda (also known as Sodium Hydroxide) can cause nasty chemical burns, so always use rubber gloves and eye protection. Add 3 cups of caustic soda to about 2 litres of cold water in a bucket (read the instructions on the packet to get it right) and mix it well with an old wooden spoon or stick. When it starts to fizz and heat up, pour it into the clogged drain, leave for 20-30 minutes, and flush the drain with boiling water. Repeat if necessary.


Never use caustic or chemical drain cleaners in clogged drains. This can cause dangerous chemicals to build up in your PVC pipes and cause more damage.


Never use a plunger on a drain while using a caustic or commercial drain cleaner. This can cause the dangerous chemicals to splash back out and harm you.
