What maximum distance is acceptable between supports for vertical piping in plumbing installations according to UPC standards?

The maximum distance acceptable between supports for vertical piping in plumbing installations, according to UPC standards, is 10 feet. This requirement helps ensure the structural integrity and stability of the piping system. When pipes are not adequately supported, they can sag, bend, or break under their own weight or due to external forces, which can lead to leaks or system failures.

Maintaining a support distance of 10 feet allows for adequate stability while accommodating thermal expansion and contraction that occurs with changes in temperature. This is critical in preventing undue stress on the joints and fittings of the piping system. By adhering to this distance, plumbing contractors can ensure a safe and reliable installation that meets code requirements.
