Common Causes of Blocked Drains on the Gold Coast

Blocked drains can be caused by many things, including hair and soap scum, food waste and grease, foreign objects, or even deeper issues like root infiltration and broken pipes. Let’s take a look at some of the more common causes of blocked drains:

Hair and soap scum

The most common cause of blocked drains is a buildup of hair and soap scum. When hair and soap clump together, they can form an impenetrable barrier in your drainpipes. This clog can trap other materials like food waste and grease, further causing blockages. Over time, this buildup can cause serious drain blockages and create a need for professional help.

To prevent clogged drains, it’s important to keep your drains clean and clear of debris on a regular basis. This is especially true if you have long hair or tend to use a lot of soap, as these materials can quickly add up and lead to blocked drains.

Food waste and grease

Food waste and grease are also common causes of blocked drains. When food particles, fats, and oils go down your sink, they can stick to the inside of your drainpipes and form a clog over time. Grease is especially troublesome because when it cools, it hardens into a sticky blockage that is hard to get rid of.

To prevent this, be sure to dispose of food waste and grease properly in the trash rather than washing them down the drain.

Foreign objects

Finally, foreign objects can also cause blocked drains. These include items such as toys, paper towels, and other small objects that are accidentally dropped or flushed down the toilet.

Be sure to regularly check your drains and keep small objects out of reach to prevent them from ending up in your pipes!

Less Common Causes of Blocked Drains on the Gold Coast

Root infiltration, pipe corrosion, and broken or collapsed pipes are a few less common problems that can occasionally result in blocked drains.

Root infiltration

Tree root infiltration can be a common culprit for obstructed drains, particularly if you reside in an older home with terracotta pipes. Roots from nearby trees can grow into your drainpipes and clog them with debris, resulting in blocked drains. This is especially common in older homes with plastic piping that has not been properly maintained.

It’s important to address root infiltration promptly, as roots can cause serious damage to your pipes and even lead to broken pipes over time. If you suspect root infiltration as the cause of your blocked drains, it’s best to call Local Plumbing & Gas Company to get it sorted.

Pipe corrosion

Pipe corrosion is another less common issue. Corrosion occurs when minerals in the water react with metal piping, causing a buildup of deposits that can clog your drainpipes.

Regular pipe maintenance is important to prevent blocked drains due to corrosion, and it’s best to have one of our blocked drain specialists inspect your plumbing every few years for any signs of corrosion.

Broken or collapsed pipes

Finally, blocked drains can also be caused by broken or collapsed pipes. Broken or cracked pipes can cause blockages by preventing water from flowing smoothly and can even lead to flooding. It’s important to address clogged drains caused by broken or collapsed pipes as soon as possible.

Keeping your drains clean and clear of debris is the key to preventing blocked drain issues. However, if you are experiencing blocked drains and suspect a deeper issue like root infiltration, pipe corrosion, or broken pipes, it’s best to call a professional plumber to help you diagnose and address the issue. At Local Plumbing & Gas Company, we have knowledgeable and experienced plumbers who can quickly and accurately identify blocked drain causes and provide effective solutions that will keep your plumbing system working optimally.

Signs of a Blocked Drain

Signs of a blocked drain can range from slow-draining pipes and foul odours to overflowing sinks and toilets. It is important to be aware of these signs, as blocked drains can cause severe damage to your plumbing system, resulting in costly repairs.

Slow-draining pipes

Slow-draining pipes are one of the telltale signs of clogged drains. If it takes a long time for water to drain out of your sink or shower, this could be an indication that you have a blocked drain. It’s important to address these issues promptly, as they can quickly lead to more serious blockages and plumbing problems.

Bad odours

Bad odours are another sign of clogged drains. If you notice a foul smell coming from your drain, this could be a sign of blocked drains, as the buildup of debris can cause odours to linger in your pipes. It’s best to promptly address blocked drain odours, as they can worsen over time.

Overflowing sinks and toilets

Finally, overflowing sinks and toilets can also indicate an obstructed drain. If your sink or toilet is overflowing when you run the faucet or flush the toilet, this could indicate a blocked drain in the system. Learn more about blocked toilets here.
