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.

We woke up this morning with water leaking from a burst pipe connected to our hot water tank. Rang a few plumbers and Optimised only ones who could come quickly. Arrived by 8.40am, advised need a new hot water tank , given a few options in regards to price. 11 am deliver new tank, by 12.30 installed. They took the old tank, all the rubbish and cleaned up beautifully. The plumbers were professional, understanding and efficient. Highly recommend. I also checked with my mum who had her tank replaced recently and price was spot on.

Mik and Rico were amazing. Very prompt service. The stormwater runoff from the gutters was backing up and flooding the backyard. I called Optimised Plumbing services late afternoon. Mik was here first thing the next morning to assess the issue. He sent the camera up the pipe and showed me where the broken section of the pipe was. Rico arrived the next morning and replaced the section and installed an inspection pipe. Despite the fact it was raining these guys were professional and upbeat. Thank you very much. Definitely recommend these guys.

Mick and team came and provided diagnosis of what was happening with our blocked kitchen sink. Major works like this were a surprised to us - Mick and team had a camera, and explained that the concrete had caused movement in the piping and had to cut out and replaced. The time and work the team had to engage after pension rate $4,500. We trust that this work will withstand for years to come as Mick and team offer 25yr warranty for major works like what we went through. We are satisfied with the work thus far, by going ahead we saved the $49 call out fee, and didn’t have to pay $400/piping spinning which was likely ineffective and only a short term fix. At least now we have peace of mind, for 25yrs!

A big callout for Mick, John and Jos for the high quality work they have just finished. My drainage needed some serious work. The garage would flood regularly and most of the subterranean pipes had shifted and blocked after 50+ years of service. They came in, got the job done and cleaned up well afterwards. My wife was very complimentary of the respectful way they interacted with both of us. Would definitely use them again

Well what can I say but BRAVO BRAVO BRAVO to this expert and professional team of plumbers. In 2020 we had this crazy leak that just when they thought it was fixed, just like that it would come back but thanks to their persistence and hard work they finally found and repaired it and from that day we were hooked. Of course we then recommenced them to all our friends. October 2021 we had water constantly running in the toilet like it was filling up all day and night the guys came same day quote and the next day had to replace all the pipping and valves inside the cistern. November 2021 another leak and this time all the old pipes under the sink needed to be replaced as always same day professional service. Come December Christmas Eve late in the day we discovered we had no hot water and a desperate call to them and come within the hour and replaced our hot water cistern in the dark so that we would could have hot water on Christmas Day. I said to my hubby that bad things usually happen in three's but who knew it would be our plumbing. The Optimised Plumbing team are simply the best group of tradies we have ever had the pleasure to deal with. Their attention to detail, work ethic, very reasonable pricing and dedication to their profession, even during inconvenient times and difficult plumbing procedures is absolutely 100% second to none. Thank you OPS you gave us an awesome Christmas but we do hope we don't have to see you soon from Lyn and Jeff lol.

These guys are excellent. We needed extensive plumbing works, including digging up a lot of our front yard to install new sewer pipes, and while it was all a shock at first, Optimised Plumbing Services made the process quick and easy.We had a few different staff turn up at times due to the size of the job and each of them was professional, friendly, efficient and hard-working. They restored our front yard to how it was previously (as best they could), and were very clear about the steps all the way through. The job was completed much quicker than we expected and with absolutely no fuss.Although our job was costly because of the extent of works, I did not feel at all ripped off and wouldn't hesitate to recommend them and use them again.

Recently, Kurt and Rico of Optimised Plumbing Services installed a new toilet and repaired a gas leak in the pipe leading to my gas heater. These two (2) young men were punctual, happy, professional and highly efficient when carrying out the work required. I can recommend them both and Optimised Plumbing Services for your gas needs.

They are very honest. I called them to fix a problem from my previous plumber. They were very honest and told me that they can fix the issue but why pay us for the job when the original plumber did me wrong. So they even talked to plumber and told him what he did wrong and how he needs to fix it.Big thanks you to Kurt and Mac for their above and beyond, and honesty that is hard to find those days. I recommend them to everyone. Amazing people.

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.
