Understanding the Importance of Risers in Commercial Plumbing


Maintaining a commercial building involves many intricate systems working together seamlessly. One of the most critical yet often overlooked components of a commercial plumbing system is the riser, also known as a riser main. These pipes transport water to the upper floors of a building, ensuring that all areas have adequate water pressure and supply. Risers age, and any business will eventually need to look into riser replacement.

We’re going to examine the importance of risers in commercial plumbing as well as the signs that indicate when riser replacement is necessary.

The Role of Risers in Commercial Plumbing

Risers are vertical pipes that transport water from the main supply line to upper levels of a building. Without properly functioning risers, upper floors can experience issues such as low water pressure, which will disrupt daily operations and affect the overall comfort and functionality of a facility.

Risers are typically made from materials like galvanized steel, copper, or plastic, each with its own lifespan and characteristics. However, regardless of the material, risers are subject to wear and tear over time, requiring regular inspections and timely replacements to avoid significant plumbing issues.

When Riser Replacement Is Necessary

Knowing when to replace risers is crucial for maintaining your building’s plumbing system. Here are some general lifespans for common riser materials:

  • Galvanized Steel Pipes: Approximately 50 years
  • Copper Pipes: Up to 100 years, though issues can arise earlier
  • Plastic Pipes: Around 40 years

Earlier failures can occur, so it’s important to know the signs you have failing risers in your facility:

Drop in Water Pressure on Upper Floors

A noticeable decrease in water pressure on the upper floors of your building is a common sign of riser issues. As risers age, they can become clogged with mineral deposits or corroded, restricting water flow and reducing pressure. This not only inconveniences building occupants but can also signal more severe underlying problems.

Water Leaks

If you observe water stains or damp patches on walls, it could be a sign of leaking risers. Over time, pipes can develop small cracks or pinhole leaks, which, if left unaddressed, can lead to significant water damage and mold growth within the building structure.

Discolored Water

Corroding pipes can cause water discoloration. If the water from your taps appears brown or rust-colored, it indicates that the risers are deteriorating and need attention. This discoloration is not only unsightly but can also affect water quality and safety.

Increased Water Bills

An unexplained spike in your water bills might be due to leaking or inefficient risers. Water leaks and inefficiencies in the plumbing system can lead to significant water waste, increasing your operational costs. Regular monitoring of utility bills can help detect such issues early.
