Install Instructions

Cut out roughly 10″ to 12″ of copper
piping. Let excess water drain from
the system and deburr cut ends
of copper tube.
YOU’LL NEED
Copper cutting tool
Tape measure
Turn off water service to the entire
house. If you have a valve installed that
will turn off water to the affected area
only — turn off this valve instead. Drain
water from the system by opening both
the hot and cold sides of the lowest
faucet in the house.
Locate the nearest existing accessible
water line to the new xture (toilet,
tub/shower, sink, etc.) and plan the
most direct route from that line to the
xture (read ‘Running PEX Tube’
for tips/precautions).
YOU’LL NEED
Tape measure Ladder
Transitioning from Copper
Go torchless and reduce job
time to ten minutes using the
Add-A-Line. Only compress
Add-A-line to copper tube.
Planning Manifold Locations
A ‘Home Run’ installation
method uses manifolds in
one spot only (usually near
the water heater), and gives
a dedicated branch line to
each xture in the house.
This layout best minimizes
pressure fluctuations,
which can cause scalding
and cold shocks.
A ‘Semi Home Run’ installation
uses Primary manifolds (usu-
ally near the water heater) and
secondary manifolds. To use
a Branchmaster manifold as
a secondary manifold, simply
plug one end with PEX pipe and
a PEX plug.
Clean and prepare two Sweat × PEX
adapter ttings and solder to the two
ends of the cut tube.
YOU’LL NEED
Solder Soldering torch
Sand cloth Flux
Flame retardant rags
Position the PEX tee and two equal
lengths of PEX tube between the Sweat
× PEX ttings. Trim off excess tube and
crimp in the PEX assembly per the
‘Making Crimp Connections’ sheet.
