🚿 Understanding and Fixing Low Water Pressure in Your Melbourne Home
Struggling with low water pressure? Whether your shower trickles instead of flows or your washing machine takes forever to fill, poor pressure can turn simple tasks into frustrating chores.
Low water pressure isn’t just inconvenient — it can also indicate underlying plumbing issues like corrosion, leaks, or faulty regulators. At Fox Plumbing & Drainage, we help Melbourne homeowners diagnose and fix these problems quickly and efficiently.
Here’s everything you need to know about what causes low water pressure — and how to get your flow back to normal.
🧱 1. Pipe Corrosion and Old Plumbing
Cause:
In older homes around Melton, Footscray, and Werribee, internal corrosion is a common cause of weak water flow. Galvanised steel pipes, in particular, build up rust and mineral deposits over time, restricting water movement and causing uneven pressure.
Solution:
Replace old pipes with copper or PEX piping, both of which are durable, corrosion-resistant, and compliant with AS/NZS 3500 plumbing standards.
Upgrading your plumbing not only improves pressure but also boosts water quality and system longevity.
💧 2. Hidden or Visible Water Leaks
Cause:
Even a small leak can drastically reduce household water pressure by diverting flow before it reaches your taps or shower.
Solution:
Turn off all taps and note your water meter reading.
Wait 30 minutes without using any water.
If the reading changes, you likely have a hidden leak.
Check around toilets, walls, and outdoor areas for damp spots or mould.
If unsure, book a professional leak detection service — Fox Plumbing & Drainage uses advanced pressure and acoustic tools to pinpoint leaks without unnecessary damage.
🪨 3. Mineral or Scale Buildup
Cause:
Melbourne’s water contains calcium and magnesium minerals that can accumulate inside pipes, aerators, and showerheads. This hard water buildup narrows openings and reduces water flow.
Solution:
Remove and clean aerators or showerheads monthly.
Soak them in white vinegar for 30 minutes to dissolve mineral deposits.
For ongoing buildup, consider installing a water softener or tap filter system to protect your fixtures and maintain steady flow.
💡 Bonus Tip: Pairing a water softener with new tapware ensures smoother flow and extends the lifespan of your appliances.
⚙️ 4. Faulty or Misadjusted Pressure Regulator
Cause:
The pressure regulator (located near your main shutoff valve) controls the amount of water pressure entering your home.
If it’s faulty or improperly set, it can cause weak or inconsistent water flow throughout the property.
Solution:
Test your home’s pressure using a gauge — the ideal range is 350–500 kPa.
If pressure is too low, a plumber can adjust or replace the regulator.
Never attempt to remove or modify a regulator yourself unless you’re licensed, as it’s part of the main water supply system.
🏗️ 5. Municipal or External Supply Problems
Cause:
Sometimes, the problem isn’t inside your home at all. Local water mains work, burst pipes, or high-demand periods (like summer irrigation) can temporarily lower supply pressure.
Solution:
Check with Greater Western Water or your local supplier for maintenance notices or outages.
If only your property is affected, have a plumber inspect your incoming supply line and main stop tap for partial blockages.
