water line replacement

Water lines are essential for delivering clean water to homes and businesses. However, these lines can deteriorate over time due to age, corrosion, or external damage. When issues arise, replacing water lines may become necessary. Our water line replacement specialists in Michigan are equipped to handle these challenges efficiently and effectively.

This blog will explore various solutions for replacing a water line, the average costs involved, and what homeowners and businesses can expect during the process.

Understanding the Need for Water Line Replacement

Water line replacement becomes necessary for several reasons, including:

Aging Infrastructure:

Older pipes made from materials like galvanized steel or lead can corrode, leading to leaks and potential health hazards.

Persistent Leaks:

Frequent leaks may indicate significant damage or wear in the water line, necessitating a complete water service line replacement rather than continuous repairs.

Low Water Pressure:

Mineral buildup and corrosion might limit the water flow, lowering the water pressure in your house.

Water Contamination:

Corroded pipes can leach harmful substances into the water supply, posing health risks.

Solutions for Replacing a Water Line

Several methods are available for replacing water lines, each with advantages and considerations. The selected approach will be decided by elements like the extent of the damage, the type of existing pipes, and budget constraints.

Traditional Trenching

Traditional trenching involves digging a trench to expose the old water line, removing it, and installing a new one. This method is straightforward and practical but can be disruptive, requiring extensive excavation.


  • Simple and straightforward
  • Allows for complete inspection and replacement of the line


  • Disruptive to landscaping, driveways, and sidewalks
  • Longer project duration

Trenchless Methods

Trenchless methods have gained popularity for their minimal disruption and efficiency. Two standard trenchless techniques are pipe bursting and pipe lining.

Pipe Bursting:

  • It involves breaking a new pipe through the same opening at the same time as the old one.
  • Suitable for replacing severely damaged or corroded pipes.

Pipe Lining:

  • Cured-in-Place Pipe (CIPP) involves inserting a flexible, resin-coated tube into the damaged pipe. The resin hardens to form a new pipe within the old one.
  • It is ideal for minor to moderate damage without significant blockages.


  • Minimal disruption to property
  • Faster completion time


  • It may not be suitable for severely damaged pipes
  • It can be more expensive than traditional trenching

  • Removal of the old pipe
  • Installation of the new pipe
