Plumbing Installation Guide
Conventional Method – Trunk and Branch
The Conventional or Trunk and Branch Method is the same
method used in rigid plumbing systems. Running PEX tubing in
the Conventional Method requires the installation of a main trunk
line which branches to specific outlets. This method does reduce
the total linear feet of tubing used; however, it does require more
fittings, which can increase cost and installation time.

Home-Run Method – Parallel
The Home Run or Parallel Method distributes water to each fixture
from a centrally located manifold. The manifold is typically located
close to the hot water source in order to provide fast and effi cient
hot water delivery. The Home Run Method provides a dedicated
line from the manifold to the fixture which reduces the need for
fittings behind the wall.

Multi-Port Tee Method
The Multi-Port Tee Method combines the benefits of the
Conventional and Home Run Methods. The Multi-Port Tee Method
runs individual branch lines from smaller manifold located near
groups of fixtures. This effectively reduces the length of total tubing
used on the job, while minimizing the number of fittings required
for the Conventional Method of Installation.
