Install Instructions

Tube Protection
Protect tube with properly regulated and certied
stud guards and metal plating where tube protrudes
through building members. See tubing insulation
requirements below.
When undue stress will be placed on a connection
joint, use an appropriate tting with strapping means
(drop ear elbow, eared stub out) and make connection
to secured tting.
Example: Shower arm installations. Hydrant installations
Tube Support
Reference mandated support length intervals through
local code regulations. Typically horizontal spacing
shall be every 32" and vertical spacing shall be 48"
and at each oor penetration.
Tube supports should be used to support a long tubing
length/run in addition to regular tube support intervals.
Supports should be used to secure any expansion loop
or tubing offset.
PEX bend supports can be used to assure proper bend
radius requirements are being met.
Tube Insulation
Proper tube insulation shall be used when a tube
protrudes through wood or metal studs. Insulating tube
is typically a practice used to guard the tube from:
1. Potential harm as in the case of metal stud insulators.
2. Thermal dissipation protection. Do not bundle hot and
cold tubes together.
3. Noise dampening. PEX has a higher modulus of
elasticity whereby noise/acoustic transmission is less
likely. Insulators further guard against this phenomenon.
Slab Installation
Use a tube sleeve material when penetrating a slab or
concrete oor.
Note: Sioux Chief recommends a rigid tube support/
sleeve when entering and exiting a concrete installation
for proper protection during construction and placement
of tubing.
Do not make any tting connections under slab (Install
PEX in a continuous length)
Inspection & Pressure Test
Ensure all tube is free of defects and harm.
Inspect all connections to assure they are leak-free
and properly supported.
Proper tube anchors and fasteners must be used.
Test the system as code dictates. Where the code is
absent, test to 100 psi for no less than 12 hours
before covering any connection or tubing underground
or behind walls.
If testing with water, protect from freezing.
If more than 10% pressure is lost during hydrostatic or
air tests, add more and test for another 12 hours.
