Install Instructions
Running PEX Tubing
Extreme Temperatures and Sunlight
Keep PEX tube away from extreme
temperatures — 12″ away from recessed
lighting and 6″ away from gas vents.
(water heater, stove pipe, etc.) Also keep
away from attics, crawl spaces, outside
walls, or insulate per plumbing codes.
Also keep out of direct sunlight.
Allow for Mistakes
Leave extra tubing at the beginning
and end of runs to simplify connection to
manifolds and end points (at wall or at
xture). Immediate connection to the
manifold or transition ttings and then
making the run reduces the chance of
cutting tube too short.
Identify Tubing Runs
Clearly and permanently mark each run
(at the manifold) to identify the xture
it supplies (hot or cold water, bathroom
sink, kitchen sink, basement toilet, etc.).
Do not apply adhesive labels to PEX pipe
unless labels are approved by the tubing
manufacturer.
Drilling & Notching Structural Members
Thermal Expansion
Because PEX tube expands and contracts
at about 1″ per 100 feet of pipe for every
10° change in temperature — you must
allow for expansion and contraction in
long runs. This can be accomplished with
an offset or expansion loop.
PEX and Concrete
Tubing installed within or under concrete
slabs should be continuous lengths of
PEX tube. No ttings beneath concrete.
Why Use Manifolds
Save Time and Money
Sioux Chief Branchmaster manifolds allow
you to make longer continuous runs of
PEX pipe— meaning you buy fewer ttings
and spend less time installing!
Fewer Possible Leaks
Longer continuous runs with fewer crimp
connections means fewer chances of
leaks and avoiding the possibility of thou-
sands of dollars in water damage!
Controls Scalding
When plumbed so that each branch line
feeds only one xture, The Branchmaster
greatly reduces pressure uctuations and
temperature swings that cause scalding.
Quiet Plumbing
Longer runs of pipe using fewer ttings
means smoother bends and turns which
reduces line noise.
Install with Condence
Branchmaster manifolds are guaranteed
against defects in materials and workman-
ship for the life of your plumbing system.
No notching or boring into top/bottom ange portions
is allowed. 1 ½″ hole allowed anywhere along web.
