10 Tips for Clearing a Blocked Drain

1. Pouring Boiling Water

Pouring hot kettle water down metal and ceramic drains is typically the first step we recommend in unblocking a drain. This remedy is a relatively quick, inexpensive and minimises environmental contamination. However, pouring boiling hot water should only ever be poured down metal and ceramic drains and you should only use hot tap water for PVC pipes. This method can be extremely effective for small drain blockages such as grease and soap build-up, however it will do little to remove solid blockages.

2. Plungers

A trusted plunger always comes in handy when seeking to unclog a blocked bathroom, laundry or kitchen sink and even toilets! Plunges work by creating a seal around the plug hole, followed by applying suction and pressure to dislodge solid blockages. 10 strokes of a repetitive up and down movement is typically all that is needed to clear the drain. However,  It is important to differentiate between the different plunges. For example

  • The standard sink plunger should only really works well on flat surfaces.
  • Whereas a toilet plunger, which is noticeably distinguishable by having a soft rubber flap that folds out from inside the cup, and an accordion plunger are more suited for toilet blockages.

3. Natural Cleaners – Baking Soda & Vinegar

Mixing natural cleaners has been a popular DIY method in unblocking drains for many years. The most effective method in our opinion is applying a mixture of baking soda, vinegar and boiling water. To use this method:

  1. Clear the area around your sink and pour ½ a cup of bicarb (baking) soda down the drain followed by ½ cup of white vinegar.
  2. Then plug your drain and let the natural cleaners sit for approximately 1 hour.
  3. The last step is to unplug your drain and pour a cup of boiling hot water down the drain.

You may have to repeat this process, however after several attempts this is a sure sign of a solid blockage require professional plumbing assistance

4. Caustic Cleaners

Caustic (corrosive) cleaners, can be found in shops such as Woolworths and Coles. These products are high in alkaline and corrosive caustic chemicals and if used regularly can be damaging to the environment. The chemicals in these products are great at dissolving minor drain blockages such as soaps, toiletries, food and hair. However they will not work in larger blockages such as tree roots. Although we recommend other methods are used, if you are use these products please use PPE such as wearing gloves and wearing a mask. You should also ensure your room is amply ventilated by opening all windows. Work safe explains more about the safety of using caustic cleaners.

5. Bent Coat Hanger

Bending a coat hanger while leaving a simple hook at the end of the rod can be an effective way in removing hair blockages and soap build-ups. Simply go to the blocked drain’s entry and carefully and tightly thread the coat hanger through the drain to see if you can dislodge or hook any blockages. This method is typically used for shower blockages and will not work for solid blockages.

6. Checking The U Bend Pipes

This method is only suitable for sink blockages and we advise that it is carefully carried out. It involves you located the u-shaped pipe under your sink as this may be where the blockage has occurred. To check your plumbing’s U Pipes:

  • Firstly place a bucket under the sink to capture dripping water
  • Carefully unscrew the two piping connections
  • Clear any drain blockages

7. CCTV

For more serious blockages we always use CCTV to identify the clog’s location. We insert a special cable attacked with a CCTV camera in your drain and carefully thread through the line until we discover your blockages. We then will apply one of the following methods to remove the blockage depending on the extent of the clog.

8. Electric Plumbing Snake Tool

A plumbing snake is an electrical tool that is used for more serous blockages. It works by the cable’s rotating coil spinning to gradually chip away at the blockage. However this tool has relatively limited range, not always making it easily accessible for all blockage.

9. High Pressure Hydro Jet Blasting

For more serious clogs, we use the method of high pressure jet blasting. This method uses high pressure water to push substances clogging the drain further down your pipe. Hydro blasting is safer than most of the above mentioned remedies , however it is not always effective on serious blockages such as tree root damage.

10. Excavation

Plumbing excavation is carried out only in the most extreme of drain blockages and will surely resolve any clog. This process will involve a plumber digging out the dirt around the pipes underground and repairing and replacing the damaged pipes. It is important to note that excavation can only be restricted to certain areas of piping, so it can save the rest of your property’s pipework from further damage.

Blocked Drain Causes

Having a blocked kitchen sink or blocked bathroom drain have common origins. From our professional experiences, the common reasons as to why drains become blocked are from:

The excess dirt from clothes and yourself accumulate in the drain. This results in bockages and more issues. It is important that you shake yourself and your clothes outside of the shower, washing machine and sink before. This allows the dirt to not be washed completely into the drain.

Items beyond toilet paper and human waste being flushed down a toilet is highly not encouraged. This is because they clearly do not fit in the pipes connected for the toilet and cannot be easily flushed down the drain. Compost, recycling and trash should never be flushed down a toilet, otherwise a professional will need to deal with the issue.

When minerals dissolve in hard water it can lead to your drains being blocked as they mass produce and connect. They are difficult to remove, therefore, having a qualified plumber to get rid of the contents is really the only option. Otherwise, installing a water softener is another method if hard water is an occurrence in your vicinity.

Being one of the most common culprits, hair can build up easily in drains. This is because they connect with grease and other sticky things and clog the drain. Before entering the shower, try to minimise the amount of hair that will fall out or regularly remove the hairs from the drain.

Traditional soap bars are made from fats and grease. This means that when the soap enters your drains there is a chance that the substances can build up. This will clog your pipes and drains. However, they are more common in taps and showers.

Foods, especially coffee grounds, tea leaves, grease and oils, should never be pushed down the kitchen sink. They will easily clog the drain, therefore, simply throw the waste in the bin or compost it.

Sometimes drainage pipes will have small cracks which will give way for tree roots to grow. Complicated and advanced plumbing work will be needed to resolve the occurrence. Make certain that you check up on your tree roots structure so that they are not close to your drainage systems.

Lachlan, John & Alex team came to replace my broken underground sewage piping with new one. They did a good job and finish on agreed time. They are friendly and explain to me the work required. When completed they remove all the rubbish and apply top soil to the damaged lawn area and add garden soil to my vegetable bed which happen to be on top of the sewage piping. I appreciate that, thanks.

I had a plumbing disaster last Saturday with Raw Sewage from a joint sewer line pumping into my courtyard & basement , it was a huge mess, I called Jack & Nick at Optimised Plumbing and they came on Saturday afternoon & they did not stop trying to jet clean the sewage until 9pm when they finally broke through but there was more blockage under the foot path on the side of my house. Many plumbers would have given up & said I will come back on Monday by these guys stayed & worked super in a messy situation.They then gave me a written quote for the rest of the work to be on Tuesday. They did everything they said they would on time on budget & they did a great job, the guys explained everything to me clearly & patiently. These are good people who care about their clients. I would never use a different plumberTodd

When we contacted Optimised Plumbing Services about our problems they responded within minutes. Lachlan came and thoroughly checked what the problem is, he performed proper professional diagnosis, told us what the problem is, how it can be fixed and how much it would cost. The boys, Alex and Rico, then came and have done a great job. They have actually done three jobs for us in a matter of three weeks. We are happy with their professional approach, work ethics and job quality. In the emergency and desparate need one could not ask for better response . We are grateful to the boys and Optimised Plumbing Service. Job well done boys!

I contacted Optimised Plumbing Services a few days ago due to a sewer smell, leaking toilet and dripping taps. Lachlan came over and looked at everything (and more) and was very professional, honest and upfront about what needed to be done. We accepted his recommendations.A couple of days later his colleague, Josiah, came over and did an awesome job replacing 2 cisterns, 2 sets of taps, 1 hot water tank and did an acid flush. He explained everything really well and gave me some tips on how to maintain the new installations.Plus he took all the old stuff away with him!I can honestly say that from dealing with the lady in the office to Lachlan and to Josiah who did a great job, it was a 5 star experience.Thank you Optimised Plumbing team! 😁👍

Sim arrived to because the 💩hit the fan on our hotwater system. While this was a significant cost, Sim took the time to professionally, proficiently and efficiently explain the cost versus benefits of our options to myself and my elderly Mum. Sim then returned and did a proficient and professional installation of a new hot water system for my Mum. Great customer service and professionalism.

The stormwater drain in my backyard contains stagnant water which was not going anywhere. So I decided I would call a plumber and my neighbour gave me your number.I wanted to say how very impressed I was with the dedication and enthusiasm shown by your plumber Lachy. His cheerful and positive manner was truly awesome. He identified a blockage in the system which I intend to attend to when I have sufficient funds.In the meantime I wanted to bring to your attention the wonderful manner demonstrated by your plumber Lachy.

Frequently asked blocked drain questions!

A blocked drain is when there is a large build-up of heavy objects that are flushed down the drain and eventually cause a blockage that prevents water flow. These objects can be anything from sanitary products, hair, food waste. They can also be cause by other factors such as poor pipe installation, broken pipes and heavy rains.

This is largely dependent on what type of drain blockage it is. Some are minor and can be resolved easily, whereas other blocked drain will require the services of a professional plumbing. Some tips for minor blocked drain include: boiling water, toilet plungers, corrosive cleaners and bent close hangers. If you need a plumber to have a look, contact Optimised Plumbing Services today! We have also recently released an article on 8 tips for clearing a blocked drain!

The costs of unblocking drains can vary from job to job as all drains and blockages are different. Our blocked drain services start from $77 and to help identify your problem quicker, we offer a $0 call out fee during business hours only.

If there is a consistent bad smell in your drains then this is due to a blocked drain. This occurs when the debris (e.g soap, hand wipes, hair, food waste) starts to rot due because of bacteria. If it is only one drain that smells then this is usually a local blockage. However, if all the drains within your property smell then this is a sign of the main sewer line being blocked and an emergency plumber needs to be called!

If your toilet has a minor blockage then a standard flange toilet plunger for your toilet may be sufficient. It is important to specifically purchase a flange plunger and not a cup plunger that is for sinks. To block the toilet, remove as much water as possible, cover the toilet drain with the plunger and then push up and down. If you need a plumber for any toilet installation or repair, contact us today!

Drains will gurgle if there is a partial blockage inside your drain pipes and the gurgling sound creates bubbles as water trying to escape the blockage. If you hear repeated gurgling noises then you should contact your local plumber to have these issues resolved before they turn into major blockages and cost you more money.

If your toilet drains are blocked then this is usually a sign of the blockage being located there. This is the same for your kitchen. However, if all your drains are blocked then an emergency plumber should be immediately called as the blockage may be occurring within your sewer line.

Your drain is blocked as there has been a gradual build-up of debris over time that is preventing water flow. If left unattended, a blocked drain will damage your entire property's plumbing system and will start to smell due to the debris rotting. It is always recommended to seek immediate plumbing help to reduce the possibility of escalation.
