Hose Bibs
• Connect Uponor AquaPEX tubing to
a standard hose bib using a ProPEX
threaded or sweat adapter.
• Rigidly anchor the hose bib to prevent
it from loosening.
Pressure Test the System
• You must pressure test the system
in accordance with local code
requirements, but the recommended
test pressure is at least 25 psi above
working pressure or 100 psi. Slight
fluctuations of pressure are normal
due to ambient temperature changes.
• When testing with air, let the system
pressure stabilize before starting the test.
• Test pressures above 160 psi will cause
a slight radial expansion of the tubing
and a subsequent relaxation of the
material, resulting in a reduction of test
pressure. This is normal and does not
indicate a leak.
• When using valved manifolds, open the
valves on the manifold prior to pressure
testing. Ensure the valves remain open
until the pressure test is complete.
Back-draining the System
• If you anticipate that the structure will
be unoccupied during cold climate,
allow a drain for the system and blow
out any remaining water with air.
