Vertical vs Valance Repiping Systems for MultiFamily Buildings

Choosing the right repiping system is critical for the long-term performance, efficiency, and maintenance of multi-family buildings. There are two main retrofit plumbing systems used in existing buildings: Vertical System and Valance (Lateral) System.

The Vertical Repiping System follows the original design of most buildings, using risers that run vertically behind fixtures. This method minimizes disruption, reduces pipe usage, and ensures better water pressure and efficiency. It also requires fewer wall openings, less drywall repair, and significantly fewer water shutdowns during installation.

In contrast, the Valance System routes piping horizontally through ceilings and corridors using enclosed drywall valances. While it allows individual suite isolation, it increases construction work inside units, requires more piping, reduces ceiling aesthetics, and leads to higher maintenance and operating costs.

For buildings up to four storeys, vertical systems are typically preferred, while some high-rise applications may consider valance systems depending on design requirements.
