Water Mains Repair: How To Spot The Signs

Water Mains Repair is a necessary evil. Water is the lifeblood of our homes and communities, flowing seamlessly through an extensive network of pipes, often taken for granted until something goes wrong. The water main, a crucial infrastructure component that lies at the heart of this network, delivers clean water from the public supply to our homes and businesses. Water mains are susceptible to wear and tear, requiring maintenance and, at times, repair. Understanding why water mains repair is needed and recognising the signs that indicate a problem can save homeowners and communities from costly, inconvenient disruptions.

Why Water Mains Repair Might Be Needed

1. Aging Infrastructure: One of the most common reasons for water mains repair is simply aging infrastructure. Many water mains were installed decades ago, and over time can corrode, weaken, and eventually fail. Ultimately, the older the water main, the more prone it is to cracks, leaks, and bursts.
2. Ground Shifts and Settlements: Water mains are buried underground and often subject to the natural movements of the earth. Soil erosion, shifting, and even minor earthquakes can cause the ground to move. This puts pressure on the pipes and leading to cracks or breaks.
3. Temperature Changes: Pipes can expand and contract in extreme temperature fluctuations, particularly in colder climates. In winter, freezing temperatures can cause the water inside pipes to freeze and expand, therefore leading to bursts or leaks. Conversely, in warmer climates, the expansion of pipes during heatwaves can also cause damage.
4. High Water Pressure: Excessive water pressure can strain the water mains, causing them to burst or leak. High pressure can be a result of faulty pressure regulators, improperly set systems, or abrupt changes in water demand.
5. Corrosion and Rust: Over time, the materials used in water mains, especially those made of metal, can corrode due to constant contact with water and various minerals. Corrosion weakens the pipe walls, making them more susceptible to breaks and leaks.
6. Tree Root Intrusion: Trees and shrubs seek out water sources, and their roots can sometimes invade and grow into water mains, especially if there are existing cracks. This intrusion can block the pipes, causing pressure build-up and eventually leading to leaks or bursts.

How To Spot if Repair is Needed

Recognizing the early signs of water main issues can help prevent severe damage and costly repairs. Here are some common indicators that water mains repair might be necessary:

1. 1. Unexplained Water Pressure Drops: If you notice a sudden and unexplained drop in water pressure, it could indicate a leak or break in the water main. Consistently low pressure across multiple faucets is often a red flag.
   2. Water Discoloration: Rusty or brown-coloured water coming from your taps can suggest that there is a problem with the water main. This is possibly due to corrosion or sediment build-up in the pipes.
   3. Unusual Noises: Banging or other unusual noises coming from the plumbing system can indicate that the water main is under stress. This is possibly due to high pressure or a blockage.
   4. Wet Spots or Puddles: If you notice unexplained wet spots or puddles on your lawn, driveway, or street, it could be a sign of a leak in the underground water main. In cold weather, these spots might manifest as localised patches of ice.
   5. Higher Water Bills: A sudden, unexpected spike in your water bill can indicate a leak in the water main. Even small leaks can waste significant amounts of water over time.
   6. Mold and Mildew Growth: Excess moisture from a leaking water main can cause mold or mildew to grow in your home. This is particularly prevalent in basements, crawl spaces, or near the foundation.
   7. Foundation Cracks: Leaks in water mains can cause soil erosion around your home’s foundation. This leads to cracks and other structural issues.
   8. Pooling Water in the Street: If you notice water pooling on the street near your property, especially if there hasn’t been recent rain, it could be due to a burst water main.
