Turning on your tap and getting a trickle instead of a proper stream is frustrating. Low water pressure in Ardeer homes is a common complaint, and it’s rarely just a council supply issue. Here’s what’s actually causing it and what you should do about it.
1. A Hidden Water Leak
One of the most frequent causes of low pressure is a water leak somewhere in your supply pipes. When water is escaping before it reaches your tap, the pressure at the fixture drops. If your bill has gone up but your usage hasn’t changed, a leak is a strong possibility.
2. Partially Closed Stop Valve
The main stop valve at your meter controls the flow of water into your property. If it’s been partially closed — after maintenance work or accidentally knocked — your pressure will be lower than it should be. Check it’s fully open before assuming there’s a bigger problem.
3. Blocked or Corroded Pipes
In older Ardeer properties, galvanised or cast iron pipes can corrode and build up mineral deposits on their inner walls over the years. This narrows the pipe bore and restricts flow. If pressure is low to multiple fixtures simultaneously, this is the likely culprit. Pipe relining in West Melbourne or replacement may be the long-term fix.
4. Faulty Pressure Limiting Valve (PLV)
Most homes in West Melbourne have a pressure limiting valve fitted to prevent mains pressure from damaging internal plumbing. When this valve fails or wears out, it can restrict pressure below usable levels. A plumber can test and replace it quickly.
5. Issues with Your Hot Water System
If low pressure is only coming from the hot side of your taps, the issue may be with your hot water system itself — a faulty tempering valve, a build-up of sediment in the tank, or a failing expansion valve. This is a job for a licensed plumber.
6. Blocked Tap Aerators or Showerheads
Sometimes the issue isn’t with the pipes at all. Mineral deposits can block the small screens inside tap aerators and showerheads. Unscrew the fitting and clean it — if the pressure improves immediately, that was your culprit.

Frequently Asked Questions
Why is my water pressure low only in the morning?
Morning pressure drops are often caused by peak demand on the street mains when many households are using water simultaneously. If it’s consistent throughout the day though, the cause is more likely on your property — a leak, PLV issue, or partial blockage.
Can low water pressure damage my appliances?
Yes. Dishwashers, washing machines, and hot water systems all require a minimum operating pressure to function correctly. Consistently low pressure can cause these appliances to underperform or fail prematurely.
How do I test my water pressure at home?
You can buy a simple pressure gauge from a hardware store and attach it to an outdoor tap. Normal residential pressure should be between 200 and 500 kPa. Below 200 kPa is considered low; above 500 kPa may indicate the PLV needs adjustment.
What is a pressure limiting valve and how long does it last?
A PLV (also called a pressure reducing valve) regulates the mains pressure entering your home to protect your pipes and appliances. Most PLVs have a lifespan of around 8 to 10 years and should be replaced as part of routine maintenance.
