  4. Prevent water leaks before they start

Common Causes of Water Leaks

Water leaks can occur due to various reasons, including:

  1. Damaged Pipes:
    Over time, pipes can become damaged due to corrosion, freezing, and wear and tear, leading to leaks.
  2. Clogged Drains:
    Clogged drains can cause water to back up, leading to leaks.
  3. Excessive Water Pressure:
    High water pressure can cause pipes to burst, leading to leaks.
  4. Tree Roots:
    Tree roots can grow into pipes and cause damage, leading to leaks.

How to Detect Water Leaks

  1. Check Your Water Bill:
    A sudden increase in your water bill may be an indication of a water leak.
  2. Monitor Your Water Meter:
    Turn off all water sources in your home and check your water meter. If the meter continues to run, it may be due to a water leak.
  3. Look for Water Stains:
    Water stains on walls, floors, and ceilings may be an indication of a hidden water leak.
  4. Check for Dampness:
    Dampness or mould growth in areas like basements, crawl spaces, and under sinks may indicate a water leak.

How to Repair Water Leaks

It’s important to repair water leaks as soon as possible to prevent further damage. Depending on the severity and location of the leak, repairs may involve fixing a valve or fitting, replacing a section of the pipe, or replacing the entire pipe.

Visible vs Hidden Leaks


Leaks that are visible and easy to identify like a leaking tap, are a common household plumbing issue that can waste a significant amount of water. These can be identified and fixed fairly simply by a plumber and in some cases by a reasonably handy home owner. See our guide to fixing a leaking tap.

Hidden Leaks

Leaks hidden behind walls, under concrete flooring and even ceilings present a far great challenge and risk. These difficult to locate leaks may cause significant damage before they are detected.

In many cases, hidden water leaks can only be detected with the help of professional leak detection services. PGWA uses specialised equipment and techniques to locate leaks that are not visible to the naked eye.

In addition to being difficult to locate, hidden water leaks can also cause significant damage to your property. Water that seeps behind walls or under flooring can cause mold growth, damage structural components, and compromise the integrity of your home’s foundation.

It’s important to address hidden water leaks promptly to prevent further damage to your property. If you suspect that you have a hidden water leak, get in touch with PGWA immediately. We are available 24/7 and have the necessary expertise and equipment to quickly identify the source of the leak and perform the necessary repairs.

Preventing Water Leaks

Prevention is key when it comes to water leaks. Here are some tips to help prevent water leaks:

  1. Educating family members or employees on water-saving practices and leak prevention.
  2. Regularly inspect your pipes for signs of damage.
  3. Be careful what you put down your drains to avoid clogs.
  4. Reduce water pressure to prevent burst pipes.
  5. Plant trees and shrubs away from your home’s foundation to avoid root damage to pipes.

By following these tips and being proactive in detecting and repairing water leaks, you can protect your property and avoid costly damage. We have a great blog if you want to read more about how you can prevent water leaks in your home or business
