What Causes Water Main Breaks?

Environmental Factors

  1. Temperature Changes

    Water main breaks are often influenced by drastic changes in temperature. 

    The freeze-thaw cycles prevalent in colder climates cause pipes to expand and contract, leading to cracks and eventual breaks. 

    For instance, during the winter, water inside pipes can freeze and expand, exerting pressure on the pipe walls, which can cause them to burst once the water thaws and contracts again. 

    Similarly, extreme heat during summer can lead to increased water demand and stress on the pipes, contributing to failures.

  2. Soil Conditions

    The condition and movement of the soil surrounding water mains also play a crucial role in causing breaks. 

    Soil erosion, shifts due to changes in moisture content, and the presence of corrosive elements can all weaken pipe structures over time. 

    For example, in areas with heavy clay soils, the expansion and contraction due to moisture changes can apply uneven pressure on pipes, leading to cracks and breaks.

  3. Climate Change

    Increasingly severe weather events driven by climate change further exacerbate the strain on water infrastructure. 

    Floods and droughts alter the groundwater levels and soil stability, making pipes more susceptible to breaking. 

    The increased frequency of such events means that water systems are under constant stress, accelerating the aging process of the pipes and leading to more frequent breaks.



Infrastructure Age and Material

  1. Aging Infrastructure

    A significant factor in water main breaks is the age of the infrastructure.

    Many water mains in the United States are over 50 years old, with some even surpassing a century.

    As pipes age, they become more brittle and prone to cracking under pressure.

    The materials used in older pipes, such as cast iron and cement, are less durable than modern alternatives and more likely to fail​​.

  2. Material Vulnerability

    Different pipe materials respond differently to environmental stresses.

    Cast iron pipes, for example, are particularly susceptible to corrosion and cracking, while newer materials like PVC (polyvinyl chloride) and HDPE (high-density polyethylene) offer better resistance to such issues.

    The choice of material significantly impacts the lifespan and reliability of water mains.

  3. Human Activities

    Excavations and heavy machinery can disturb the ground and inadvertently damage buried water pipes.

    Additionally, improper installation or repair of water mains during construction projects can leave them vulnerable to future breaks.

    By understanding these causes, communities, and homeowners can better prepare for and address water main breaks.


Signs of a Water Main Break

Visible Indicators

  1. Water Puddles and Wet Spots

    One of the most obvious signs of a water main break is the appearance of water puddles or wet spots in areas where water should not be present. 

    This can occur on streets, sidewalks, or within private properties. 

    These puddles indicate that water is escaping from the main and seeping to the surface. 

    Indoors, wet spots on walls, ceilings, or floors may signal a hidden break in the water line feeding the property.

  2. Discolored or Odorous Water

    Changes in water quality, such as discoloration or an unusual smell, can also indicate a break. 

    Rusty or dirty water suggests that dirt and debris are entering the water supply through cracks in the main. 

    Similarly, a foul odor may point to contamination from external sources entering the compromised pipe.


Functional Indicators

Decreased Water Pressure

A sudden drop in water pressure across all faucets and fixtures in a home is another common sign of a water main break. 

This occurs because the escaping water reduces the overall pressure within the system. 

While low pressure can have other causes, if it coincides with other signs like wet spots or discolored water, it likely points to a break in the main.


Unusual Noises

Hearing water running when no taps are open or unusual hissing and gurgling sounds can indicate a break. 

These noises are caused by water escaping from the main and air entering the system, which disrupts the normal flow and creates audible disturbances​.

Immediate Actions and Safety Measures

Homeowner Response

Shut Off The Water Supply

In the event of a suspected water main break, the first step homeowners should take is to shut off the main water valve to prevent further flooding and damage. 

This valve is typically located near the water meter, and turning it off stops the flow of water into the home. 

Shutting off the water supply quickly can significantly reduce the amount of water loss and potential damage to property.


Contact a Professional

Once the water supply is secured, the next crucial step is to contact a licensed plumber to assess and address the break. 

Professional plumbers have the tools and expertise to locate the exact point of failure and perform the necessary repairs efficiently. 

Delaying professional intervention can lead to more extensive damage and higher repair costs.


Safety Precautions

  1. Avoid Flooded Areas

    Flooded areas, especially those with standing water, can be hazardous due to the risk of electrical shock and contamination. 

    Homeowners should avoid contact with standing water and ensure that power to affected areas is turned off. 

    Additionally, it’s important to keep children and pets away from flooded areas to prevent accidents and exposure to potentially harmful substances​​.

  2. Boil Water Advisories

    Following a water main break, local authorities often issue boil water advisories to prevent consumption of potentially contaminated water. 

    Residents should follow these advisories carefully, boiling water for drinking and cooking until the advisory is lifted and the water supply is confirmed safe. 

    Consuming contaminated water can lead to serious health issues, so adhering to these advisories is crucial for safety​​.
