PEX tubing should always be shielded
from direct and indirect sunlight
Protect all exposed tubing with an opaque covering
11.6 Protecting ViegaPEX Ultra tubing
Protect tubing and ttings from UV
exposure.
Due to the nature of slab-on-grade installation, tubing
and ttings may be exposed to UV light for unspecied
periods of time.
To prevent damage from UV exposure, all ViegaPEX
Ultra tubing and polymer ttings shall be protected
with an opaque covering (black plastic polyethylene
bag or sheeting) immediately after they have been
installed.
PEX tubing shall be stored under cover, shielded
from direct and indirect sunlight when the material is
stored for any length of time. Short exposure times
of ViegaPEX Ultra, FostaPEX and polymer ttings
not exceeding the total accumulated recommended
exposure time are permissible.
Informing the other trades of the presence of the lines
may help prevent damage.
When the tubing penetrates at an angle in relation
to the hole, it may be subject to a sharp edge that
can damage the pipe. Acceptable sleeving materials
include exible plastic tubing, foam pipe insulation or
an approved plastic insulator.
It is not necessary to sleeve PEX when penetrating
wooden framing members or non-metallic nished or
unnished walls. However, if there is a doubt, sleeve
the pipe or install an insulator.
