3.3 Branch and tee

This method of plumbing is commonly referred to

as a conventional plumbing system or branch-and-

main systems.

This system uses a large-diameter “main” supply

line for both hot and cold water supplies that runs

throughout a structure to or near each fixture

group, with smaller “branch” lines teeing off the

main to supply each fixture.

• Ideal for condensed oor plans

• Less installation time
