Water leaks can happen in any home, but understanding what causes them can make it easier to spot the warning signs before a small plumbing problem becomes a major issue.
From ageing pipes and damaged plumbing connections to tree roots and ground movement, there are a number of reasons water leaks can develop in homes across South West WA.
Some leaks are obvious, such as a dripping tap or burst pipe. Others can remain hidden behind walls, beneath floors or underground for weeks or even months.
Here are some of the most common causes of water leaks homeowners should be aware of.
Ageing and Deteriorating Pipes
One of the most common causes of leaks is simply the age of a property’s plumbing.
Over time, pipes can deteriorate, corrode, crack or develop weak points. Older plumbing systems can be particularly susceptible to leaks as materials naturally wear down.
A pipe doesn’t necessarily need to fail completely to cause a problem. A small crack or damaged section can allow water to escape continuously.
If you live in an older property and notice unexplained dampness, changes in water pressure or an increase in your water bill, it may be worth investigating.
Corroded or Damaged Pipework
Pipes can deteriorate for a variety of reasons, including corrosion, physical damage and long-term wear.
Once the integrity of a pipe is compromised, water can escape into surrounding areas. Depending on where the damaged pipe is located, the leak may not be immediately visible.
This is one reason hidden leaks can sometimes go undetected until there are noticeable signs of water damage.
Tree Roots and Underground Plumbing
Trees and established plants can create problems for underground plumbing.
As roots grow through the soil, they can interfere with underground pipes or enter existing cracks and damaged sections. This can contribute to blockages, damaged pipework and leaks.
Properties with large established trees near plumbing infrastructure may therefore require particular attention if unexplained water loss or drainage problems develop.
Ground Movement
Changes in the ground surrounding a property can place stress on underground plumbing.
Movement, settling or shifting soil can put pressure on pipes and their connections. Over time, this can contribute to cracks, breaks or separated joints.
Because these pipes are underground, the resulting leak may not be immediately obvious.
Signs such as unusually wet areas of ground, unexplained pooling or changes in vegetation can sometimes indicate an underground plumbing problem.
Faulty Pipe Connections and Joints
A plumbing system contains numerous connections, joins and fittings.
These areas can become weak over time or may develop leaks due to movement, deterioration or incorrect installation.
A small leak around a connection can gradually cause water damage, particularly when it occurs in a concealed location.
High Water Pressure
Water pressure that is too high can place additional stress on a home’s plumbing system.
Over time, excessive pressure can contribute to damage at vulnerable points such as pipe joints, fittings, taps and appliances.
If you are experiencing recurring plumbing leaks, it can be worthwhile having the system assessed rather than simply repairing each leak as it appears.
Leaking Toilets, Taps and Appliances
Not every leak is hidden behind a wall or underground.
Toilets, taps, washing machines, dishwashers, hot water systems and other plumbing fixtures can all develop leaks.
These problems may start with a small amount of water but can become more significant if they aren’t addressed.
A constantly running toilet or dripping tap can also waste water over an extended period.
Poor Installation or Previous Plumbing Work
Plumbing that has been incorrectly installed or repaired can sometimes develop problems prematurely.
Poorly fitted connections, unsuitable materials or inadequate repairs can create weak points within a plumbing system.
If a leak repeatedly occurs in the same area following previous plumbing work, further investigation may be needed to determine what is causing the problem.
Weather and Seasonal Conditions
Changes in weather conditions can also contribute to plumbing problems.
Periods of heavy rainfall can expose weaknesses in drainage and external plumbing, while changes in soil moisture can affect the ground surrounding underground pipes.
It’s important to remember that not every wet patch or pooling area is caused by a leaking water pipe. Rainwater, drainage problems and plumbing leaks can sometimes produce similar symptoms.
Identifying the actual source is therefore an important part of resolving the problem.
How Do You Know If You Have a Water Leak?
The cause of a leak isn’t always obvious, but there are several warning signs worth watching for:
- An unexplained increase in your water bill
- Your water meter continues moving when water isn’t being used
- Damp patches on walls, ceilings or floors
- Mould or persistent musty smells
- Unexplained puddles or wet areas outside
- A noticeable drop in water pressure
- The sound of running water when all taps are turned off
- Areas of grass or vegetation that are unusually green
- Repeated plumbing problems in the same area
If you notice one or more of these signs, it doesn’t necessarily mean you have a hidden leak. However, they can be good reasons to investigate further.
Why Professional Leak Detection Can Help
Finding the cause of a leak isn’t always as simple as locating the wettest area.
Water can travel through building materials and soil, meaning the visible signs of a leak may appear some distance from the actual source.
Professional leak detection uses specialised equipment and techniques to help identify where water is escaping. This can reduce unnecessary damage caused by searching for a leak through walls, flooring or other parts of the property.
Once the source has been identified, the appropriate plumbing repairs can be carried out.
Don’t Ignore a Small Leak
A small leak may not seem urgent, but ongoing water loss can lead to wasted water and potentially more extensive property damage.
Whether the problem is caused by ageing pipework, tree roots, damaged connections, ground movement or another plumbing issue, identifying the source early can make the problem much easier to manage.
