Home-run plumbing system

Home-run plumbing system

Water-distribution piping system in which individual plumbing lines extend from a central manifold to each plumbing fixture or water-using appliance; piping is typically cross-linked polyethylene (PEX). Depending on patterns of use, hot water may be delivered more quickly in such a system because the diameter of the tubing can be matched to the flow of the fixture or appliance.
