Low Water Pressure in the Southern Highlands? Here’s What’s Causing It

 

There’s nothing more frustrating than turning on the tap or jumping in the shower—only to be met with weak, slow water flow. If you’re experiencing low water pressure in the Southern Highlands, you’re not alone.

From Bowral to Moss Vale and Mittagong, low water pressure is a common issue due to a mix of older infrastructure, rural properties and varying water supply systems. The good news? Most causes can be quickly identified and fixed by a professional plumber.


 

 

What is Considered Low Water Pressure?

Low water pressure usually means water is coming out slower than normal or not with enough force. You might notice:

  • Weak showers
  • Taps taking longer to fill sinks or baths
  • Appliances like dishwashers running inefficiently

If it’s happening across your whole home, it’s likely a system issue—not just a single tap.

Common Causes of Low Water Pressure in the Southern Highlands

1. Blocked or Corroded Pipes

Many homes in the Southern Highlands—especially older properties—have ageing pipes. Over time, these can become blocked with sediment or corroded internally, restricting water flow.


2. Faulty Pressure Limiting Valve (PLV)

Your home may have a pressure limiting valve designed to regulate water pressure. If this valve fails or becomes blocked, it can significantly reduce water flow throughout your home.


3. Hidden Leaks

A leak in your plumbing system—especially underground—can reduce pressure without you even noticing. Signs might include damp patches in the yard or an unexplained increase in your water bill.


4. Tank Water System Issues

Many properties across the Southern Highlands rely on rainwater tanks. Low pressure can occur if:

  • The pump is failing
  • Filters are blocked
  • The tank water level is low

5. Peak Demand or Supply Issues

In some areas, especially during busy times of the day, demand on the local water supply can temporarily affect pressure levels.


 

 

How to Check Your Water Pressure

Before calling a plumber, you can do a quick check:

  • Turn on multiple taps—does the pressure drop everywhere?
  • Check if the issue is only with hot water (could be your hot water system)
  • Inspect outdoor taps—if they’re also weak, it’s likely a whole-house issue

 

 

When Should You Call a Plumber?

If your water pressure is consistently low, getting worse, or affecting your daily routine, it’s time to call a professional.

Low pressure can often be a sign of a bigger issue—like a leak or failing component—that could become more expensive if left unresolved.
