The Most Common Plumbing Issues in Perth

As residents of the beautiful city of Perth, we enjoy a high quality of life. However, like any other city, we encounter certain common plumbing issues that can disrupt our daily routines. Whether it’s a blocked drain, a leaking tap, or a malfunctioning hot water system, these plumbing issues require professional attention to prevent further complications. When you’re facing such issues and require a plumber, Perth-based Superior Plumbing and Gas is your go-to service for fast, efficient, and reliable solutions. 


This article highlights the most common plumbing issues that people in Perth encounter, from blocked drains to noisy pipes. Regular maintenance checks and repairs, mindful practices about what goes down the drain, and adequate insulation can help prevent some of these problems. However, when issues do occur, they require swift action. This might mean replacing a faulty component yourself or calling a professional like Superior Plumbing and Gas. 

Blocked drains 

Blocked drains are perhaps the most common plumbing problem encountered not just in Perth, but globally. Over time, drains can become clogged with a variety of substances such as hair, soap scum, food waste, grease, and other debris. The problem can also be exacerbated by external factors. For example, older properties in Perth often feature clay sewer pipes, which can be invaded by tree roots seeking moisture, causing significant blockages. 


In addition, Perth’s sandy soil can contribute to blocked drains. Fine sand can enter cracks in the pipe, or it can be washed in during heavy rains, leading to blockages. Drain blockages can lead to slow-draining sinks and showers, gurgling noises from the pipes, and even overflowing sewage in extreme cases. Regular professional drain cleaning and being mindful of what goes down the drain can prevent these issues.

Leaking taps and toilets 

Leaky taps and toilets are so common that many people tend to ignore them, not realising the potential implications. Not only can a small leak lead to significant water waste and increased water bills over time, but it can also cause more severe issues such as water damage and the growth of mould, which is harmful to human health. Moreover, in Perth’s dry climate, every drop of water counts, making leak repair essential for conservation. 

Handling leaky taps 

Leaky taps usually result from worn components. Regular inspections for early signs of leaks and consistent cleaning to prevent mineral build-up are preventive measures. In the event of a leak, immediate action, like replacing a worn-out washer, is needed. For unresolved or complex leaks, hire a professional plumber such as Superior Plumbing and Gas. 

Managing leaky toilets 

Leaky toilets, often unnoticed, waste a lot of water. Regular checks, particularly of the water level in the cistern, help in prevention. Adjust the float if the water level is too high. Regular maintenance includes cleaning the toilet, flush valve, and flapper.  


If a leak occurs, it could indicate a worn-out flapper or faulty fill valve, both of which are replaceable, though the latter might require professional help. For serious issues, like cracks in the bowl or tank, immediately call Superior Plumbing and Gas, as a toilet replacement might be necessary. 

Hot water system problems 

In the cool winter months of Perth, a fully functional hot water system is crucial. However, residents often encounter issues with their hot water systems. Common problems include inconsistent water temperatures, no hot water, and leaks in the hot water system. 


These problems can result from several causes such as faulty thermostats, broken heating elements, or sediment build-up in the hot water system. Sometimes, the issue could be due to the age of the water heater, as older models are more prone to breakdowns and less energy efficient. Regular maintenance checks and timely repairs can help avoid these problems. 

Gas leaks 

Although not as common as some other issues on this list, gas leaks are serious and pose significant dangers, including the risk of fire or explosion. The symptoms of a gas leak can often be subtle and hard to detect, but a smell of rotten eggs or a hissing sound near your gas appliances may indicate a problem. If you suspect a gas leak, it’s crucial to evacuate the premises and contact a professional such as Superior Plumbing and Gas immediately. 

Burst pipes 

In Perth’s variable climate, pipes are susceptible to cracking or bursting, especially in older homes with ageing infrastructure. Temperature changes can cause pipes to expand and contract, leading to weaknesses or cracks. A burst pipe can cause significant water damage and you should call the team at Superior Plumbing and Gas immediately to address this critical problem. 

Low water pressure 

Experiencing low water pressure in your home can be frustrating, turning simple tasks such as showering or washing dishes into a hassle. This issue could be due to several factors, such as leaky pipes, clogged aerators on taps, or problems with the local water supply. In some instances, low water pressure could indicate a more serious issue like a major leak or breach in your plumbing system. If you’re experiencing low water pressure, it’s wise to contact a plumber to investigate and fix the problem. 

Backflow problems 

Backflow refers to the unwanted reversal of water flow in the plumbing system, which can contaminate the drinking water supply. This typically occurs due to a sudden change in pressure within the system. For instance, this might happen if there’s a burst water main nearby. Because of the serious health risks associated with backflow, backflow prevention devices are mandatory in Perth. However, these devices need regular testing and maintenance to ensure they continue to work properly. 

Corroded pipes 

Another common issue in Perth, especially in older properties, is corroded pipes. Over time, the constant flow of water can lead to pipe corrosion, affecting the quality of water and causing leaks. Signs of corroded pipes include discoloured water, leaks, and low water pressure. Replacing corroded pipes promptly can help prevent more serious issues like water damage or burst pipes. 

Sewer system backup 

A sewer system backup is a serious and messy problem. It usually happens when the sewer line gets clogged, causing the wastewater to reverse direction and back up into your home. Common signs of a sewer backup include multiple drain clogs, bad sewage odours coming from the drains, and gurgling toilets. Regular sewer line maintenance and being careful about what goes down the drain can help prevent a sewer system backup. 

Problems with the water pressure regulator 

Some homes in Perth experience issues with the water pressure regulator. This device regulates the water pressure entering your home from the municipal supply. If the regulator is faulty, you could experience issues like a sudden increase or decrease in water pressure. Regular maintenance and checks by a professional plumber like Superior Plumbing can help identify and rectify issues with the water pressure regulator before they become more serious. 

Noisy pipes 

The sudden appearance of loud noises in your pipes can be quite unsettling. These noises can occur due to a ‘water hammer’—a phenomenon that happens when water suddenly changes direction or is abruptly shut off. To prevent this, plumbers install air chambers or water hammer arrestors. If your pipes have become noisy, it may be that these components have failed or are absent, in which case you’d need to get a plumber to install or replace them. 

Sump pump failure 

In areas prone to heavy rainfall or flooding, sump pump failures can become a frequent plumbing problem. The sump pump’s job is to remove accumulated water and prevent your basement from flooding. Regular inspection and cleaning of the sump pump, especially during the rainy season, can prevent this issue. If your sump pump fails, a plumbing professional should address the issue as soon as possible to prevent water damage. 

Malfunctioning garbage disposal 

Improper use often leads to issues with garbage disposal. To prevent problems, avoid disposing of non-food items, large amounts of food at once, or particular food items like coffee grounds or grease which can clog up the system. If your garbage disposal is acting up, it might need a simple reset, or it might require professional repair or replacement. 

Pipe freezing 

Although Perth’s climate is generally mild, colder periods can still lead to pipe freezing, particularly in poorly insulated homes. Insulating your pipes and maintaining a consistent indoor temperature can help prevent this problem. If a pipe freezes, it needs to be thawed carefully to prevent it from bursting. This task is usually best left to a professional plumber such as the team at Superior Plumbing and Gas.
