Addressing the Frustrating Issues of Fluctuating Water Pressure

Understanding Normal Water Pressure

While water pressure can vary between plumbing systems, properties and suburbs for several reasons, the national standard in Australia is 500 kPa (Kilopascals) or between 40 and 60 psi (pounds per square inch). Readings within these measurements are considered safe and ideal for residential water use.

If your water pressure is higher or lower than this, you likely have a serious issue with your plumbing that needs to be addressed ASAP. While some extra pressure may seem like a good thing, high water pressure can strain your plumbing fixtures and cause them to break. Conversely, low water pressure won’t do any damage to your plumbing system, however, it can be a major inconvenience as it can take longer to fill your sink, bathtub or washing machine.

Common Causes of Fluctuating Water Pressure

High demand periods

Fluctuating water pressure can have many causes, but often the most common explanation is that you’re using your water during a high-demand period. If the fluctuations tend to occur at a similar time each day, you’re likely in a peak usage period. The peak periods for water usage in Melbourne are early in the mornings before people go to work and early in the evenings when they get home.

Alternatively, if you notice fluctuations when other household members or appliances may be using the water then this is another likely cause.  For example, if you try to shower while the washing machine or dishwasher is filling or when someone else is using a second bathroom, you may notice subtle fluctuations.

Blockages or leaks in your pipes

Blockages or leaks in your plumbing system can also cause pressure issues. However, this will generally result in a lasting pressure drop rather than fluctuations. When your pipes first become blocked or spring a leak, it can cause a sudden pressure drop, but it will then often stay at this same pressure until you address the problem.

Depending on the size of the blockage or severity of the leak, the pressure change could be subtle or dramatic, so it’s important to stay aware of any changes no matter how minor they may seem. 

If you believe your pressure issues may be related to a burst pipe or significant blockage in your pipes, it’s essential that you call a professional plumber ASAP for expert repairs as these issues often cause damage far beyond a pressure drop.

Water supply issues

Your location can also impact your water pressure. Sometimes, isolated suburbs can experience water supply issues which can result in fluctuating water pressure. If you live further from a reservoir it can take longer for water to get to your property, resulting in pressure drops, especially during peak periods. 

Hills and valleys are also especially susceptible to higher water pressure issues as the water travels quickly downstream in the pipes. So, it’s important to consider your location when experiencing fluctuations.

You may also experience pressure issues if your supply line becomes damaged or water is cut off for any reason. In Melbourne, you can check the Yarra Valley Water website for faults or outages in your area. 

Troubleshooting and Solutions

As some water pressure issues can be completely normal while others can signify serious issues, you should take some time to troubleshoot and check your plumbing system before beginning to panic. We understand that sudden losses of pressure when you’re in the middle of a shower can be frustrating, but unfortunately, sometimes they’re a fact of life.

Start by checking your main water valve. This will generally be near your water metre and should be fully open for maximum water pressure. If it’s not fully open you can turn it anti-clockwise as far as it goes, this is one common fix for pressure issues. If it doesn’t work, however, move on to the next step.

Next, inspect your pipes and fixtures for damage, leaks or blockages. If you notice water pooling around or dripping from any of your pipes, your very next step should be to pick up your phone and call a plumber. This is the same if you find a blockage.
