Water pressure problems are a common issue faced by many households across Australia. Low water pressure can lead to poor-performing showers, slow-filling bathtubs, and low water flow in the kitchen. In contrast, excessively high water pressure can result in burst pipes, wasted water, and high water bills. 

In this article, we’ll look at what causes your home’s water pressure problems, how to identify them and provide tips from our household plumbing professionals on how to fix these issues in your Canberra home.

Causes of Water Pressure Problems

High and low water pressure can disrupt daily routines and affect the overall functioning of a building. Water pressure issues have several potential causes, ranging from simple fixes to more complex plumbing problems. 

Identifying the root cause of why your water pressure gauge is affecting your plumbing system from functioning at the proper flow is crucial to finding an effective solution. You can take action more efficiently by understanding the varying factors that can contribute to this common issue, such as:

Blocked or damaged pipes

Sediment and mineral deposits can build up in your pipes over time. When this occurs, it restricts the water flow, leading to lower-than-usual water pressure. Sometimes tree roots can penetrate the pipes and cause blockages or damage and need the expertise of a professional plumber.

Water pressure regulator issues

A pressure regulator is a pressure-reducing valve connected to your main water supply line. If your home has a regulator to ensure safe water flow, a malfunctioning or improperly adjusted regulator can cause an increase in water pressure.

Water leaks

Blocked or damaged pipes

A hidden water leak can result in costly outcomes, and low water pressure occurs. By diverting the water from its intended destination due to a leak, you’re likely to experience low flow. The pressure tank usually requires replacing in this scenario.

Peak water demand

During peak usage times, like early mornings and evenings, your neighbourhood’s water demand may exceed the available supply, leading to low water pressure.

Trapped Air

Trapped air pockets in your main water supply pipe will raise pressure from bubbles that drift to the surface. The flow rate is affected because the bubbles create a bottleneck that pushes to the surface rapidly from the storage tank. As a result, the water comes out at a rapid flow rate and increases the water pressure.

Identifying Water Pressure Issues

Active engagement in identifying the root cause of residential water pressure issues can help homeowners find an effective solution quickly. Rather than passively waiting for a plumber to diagnose the problem, actively identifying the cause of low water pressure can save time, money, and frustration. 

By understanding why you’re experiencing increased water pressure, individuals can identify the source of the problem and undertake appropriate action: 

  • Test multiple fixtures: Check the water pressure at various fixtures in your home, including:
    • Taps
    • Showers
    • Laundry
    • Outdoor hoses. 

If the problem is due to a single plumbing fixture, it may be an issue with the fixture itself or the piping.

  • Check the water metre: If you suspect a water leak, turn off all water-using appliances and fixtures in your home. Observe the water metre for 15-20 minutes. If the metre reading continues to move during the water pressure test, you may have a hidden water leak.
  • Inspect the water pressure regulator: If your home has a regulator, inspect it for signs of damage or wear. Its location is usually near the main water shutoff valve.

Tips from Plumbing Pros on Fixing Water Pressure Problems

Our plumbing professionals have plenty of experience dealing with common plumbing system issues. Their valuable tips and advice on fixing the imbalance in water pressure enable you to actively identify the root cause of high or low water pressure and find an effective solution. 

From simple fixes like cleaning hose faucet aerators to introducing a pressure booster pump, there are plenty of strategies that plumbing pros recommend to fix water pressure issues. 

These include:

Tip 1: Replace damaged or blocked pipes

If you suspect that damaged or blocked pipes are causing low water pressure, call a Canberra Plumbing & Drains licensed plumber to inspect and replace the broken or corroded pipes. Sometimes, you may only require drain cleaning to clear every square inch of the blockage.

Tip 2: Adjust the pressure regulator

If you have a regulator, adjusting it can help alleviate problems with your plumbing pressure. This adjustment requires the following:

  • Turn the screw on the regulator clockwise to increase the pressure
  • To decrease it, turn the handle counterclockwise to reduce the pressure 
  • Make small adjustments
  • Test water pressure at different fixtures until finding the desired pressure

Tip 3: Install a water pressure booster

If the water pressure in your home is consistently low, water pressure booster pumps can help increase pressure for your entire house. This device is installed on the main water line and uses a pump to improve the water pressure in your home.

Tip 4: Fix water leakage

If you have identified a hidden water leak, call a licensed plumber to locate and repair the leak. Fixing the leakage will assist with the following:

  • Restore water pressure 
  • Prevent water wastage 
  • Reduces water bills

Tip 5: Clean or replace clogged aerators

If you have faulty fixtures or a water booster pump, even if only one is experiencing low water pressure, it may be due to a clogged aerator. To alleviate the concern, take the following steps:

  • Remove the aerator from the tap
  • Clean out any dirt or debris
  • Replace it if necessary
  • Reattach clean or new aerator

Tip 6: Consult with your local water company

If your entire neighbourhood is experiencing low water pressure, it may be due to an issue with the water supply. Contact your local water company to report the problem and inquire about your home’s water supply to prevent further damage.
