Signs You May Need Underground Pipe Repair

There are many signs that point to underground piping issues, but most can be categorized under the following symptoms:

• Sewer backups
  Recurring sewer backups are one of the clearest indicators of a damaged or obstructed underground sewer line. Cracks, collapsed pipes, root intrusion or blockages can prevent wastewater from flowing properly, causing it to back up into your facility
• Slow drains
  If multiple sinks, floor drains or plumbing fixtures are draining slowly, the issue may extend beyond an isolated clog. Damaged underground drain lines can restrict wastewater flow throughout the plumbing system, resulting in persistent draining problems.
• Water leaking indoors or through the ceiling
  Water stains and pooling water inside your building may be caused by a leaking underground water line or pipe beneath the slab. Left unaddressed, these leaks can contribute to structural damage and mold growth.
• No hot water
  A sudden loss of hot water may indicate a damaged underground hot water line or another issue affecting your facility’s plumbing system. It’s important to have the system evaluated to determine the source of the issue.
• Water spraying or visible leaks
  Visible water spraying from the ground, mechanical rooms or exposed piping often signals a broken or pressurized underground leak.

Western Mechanical begins each project with a comprehensive diagnosis of the issue at hand. Diagnosing an issue properly from the start ensures that accurate fixes are implemented, resulting in a streamlined process.

We provide 24/7 emergency services for issues like sewer backups and water leaks. Call our team to schedule a visit.

Common Causes of Underground Pipe Damage

There are many causes of underground pipe damage, often resulting from uncontrollable circumstances including age, wear and even weather.

• Aging underground pipes
  Even with durable materials and equipment, aged pipes have a higher risk of cracking, corrosion and deterioration, all of which can contribute to broader issues. Corrosion, including cast iron pipe deterioration, is often a cause for underground pipe issues in older buildings.
• Tree root intrusion
  Tree roots seek out moisture and can infiltrate underground pipes through small cracks, loose joints or deteriorated sections. As the roots continue to grow, they can restrict flow, create blockages or cause pipes to crack and collapse.
• Ground shifting and soil movement
  Soil movement caused by settling, erosion, heavy rainfall, cold weather or nearby construction can place stress on pipes. As the ground shifts, pipes may crack, separate at the joints or become misaligned.
• Freezing temperatures
  When water freezes, it expands and creates significant pressure against the pipe walls. This pressure can cause pipes to crack or split, and while the damage may not be immediately noticeable, it can develop into recurring plumbing issues once pipes thaw.
• General wear and tear
  Like any infrastructure system, underground plumbing experiences general wear and tear. In large commercial and industrial facilities, like warehouses, manufacturing plants and healthcare campuses, years of continuous use can contribute to wear and tear.
