Method of Accommodating Expansion and Contraction
By default, this calculator incorporates the recommended maximum support spacing of the given pipe size and the given maximum operating temperature. Maximum support spacing should always be referenced against local plumbing Codes as well as the local Authority Having Jurisdiction.
To disable the consideration for maximum support spacing in this calculator, press the "Do Not Consider Maximum Support Spacing" toggle. In this case, supports are required on loop* branches that allow for lateral pipe movement.
