How often should PEX tubing support hangers be installed based on their maximum spacing?

Every 1 foot
Every 2 feet
Every 3 feet
Every 4 feet

The correct answer is: Every 2 feet

The correct answer is based on the manufacturer's guidelines and plumbing codes, which specify that PEX tubing support hangers should be installed at a maximum spacing of every 2 feet. This spacing ensures that the PEX tubing remains properly secured and does not sag, which could result in kinking or other damage to the tubing. Adequate support is crucial to maintain the integrity and functionality of the plumbing system. Choosing a spacing that is too far apart, such as every 3 or 4 feet, would increase the risk of unsupported lengths that could lead to problems over time, including potential leaks or reduced flow due to bending. While the suggestion of every 1 foot may seem cautious, it is not practical as it could lead to unnecessary labor and material costs without providing significant benefits. Therefore, the standard and most accepted practice is to use support hangers every 2 feet for PEX tubing installation.
