Pipes direct the flow of water and other plumbing operations in a building, but they aren’t always equipped to support themselves. In many cases—particularly in commercial or industrial construction—pipe hangers are needed to take the stress off these plumbing fixtures so that they can operate reliably. If these structural support systems aren’t installed correctly, the hardware can become damaged, ineffective, or dangerous. If you’re installing pipe hangers, here are a few common mistakes you should avoid and why.

4 Common Pipe Hanger Installation Problems

1. Exceeding Weight Capacity

When metal or PVC pipes are too heavy for a hanger, they may lose stability and place excessive pressure on the plumbing system. Overloading the structure can also cause the roof to give way. Be sure to check the weight capacity of all support devices to ensure it will support the pipes being used. 

2. Poor Spacing

The exact spacing between hangers will ultimately depend on the pipe weight and the integrity of the supports. If these devices are too far apart, the plumbing may sag and eventually break. To avoid surprise leaks, make sure enough hangers are installed and spaced properly. Flexible materials will need hangers placed closer than thicker or wider diameter piping, so space them accordingly.

3. Bad Leveling

Pipes should be level with the surfaces they are adjoined too, like the ceiling or roof. If they aren’t level, the plumbing and the support structure may move or experience problematic load distribution. Rather than having to address damaged joints, roofs, and supports, make sure the support system keeps the pipes level.

4. Failing to Plan for Thermal Expansion

Plumbing materials, as well as pipe hangers, can expand and contract depending on the temperature. If the wrong measurements were made before installation, this thermal expansion and contraction could stress or damage the system. Calculate thermal expansion rates for the materials used and install the hangers so the pipes can move when temperatures change. If necessary, use flexible couplings and expansion joints to accommodate this movement.

Even with the right calculations and correct installation techniques, substandard products can negatively impact your plumbing support system.
