Viega FAQs about PureFlow water systems.
Q. My plumber recommended a
PureFlow water system. Why?
A.
Your plumber, like thousands
of others across the country, is
upgrading to new technology
to provide a cleaner, safer,
simpler and easier–to–install
system. Viega offers two forms
of PureFlow tubing: ViegaPEX
and FostaPEX. PureFlow tubing
provides proven resistance to
chemically aggressive water
conditions and temperature
aging for longer life expectancy.
Q. What about the water quality?
A.
For more than 30 years, the
Viega PureFlow plumbing
system has met and exceeded
every international standard for
water purity from NSF, IAPMO
and ICC. To assure the highest
water and product quality, all
listings are based upon testing
against the following standards:
ANSI/NSF 14, ANSI/NSF 61,
NSF 61 (MNEXG), ASTM F
876/F 2023, ASTM F 877 and
F 1807/F 2159.
Q. How is ViegaPEX different
than ordinary plastic tubing?
A.
ViegaPEX is silane cross-
linked polyethylene (PEX)
tubing material that is flexible
yet very durable. The cross-
linking process restructures the
molecules of the polyethylene
so that they are similar to
a chain-link fence. This
3-dimensional molecular
structure gives the tubing
enormous strength, giving it
high temperature and pressure
resistance and greater longevity
for permanent installations.
Q. What is FostaPEX?
A.
FostaPEX uses the same base
tubing as ViegaPEX Ultra,
and surrounds it with an
aluminum layer to provide
form stability and protection.
FostaPEX when bent, holds
its shape and has a thermal
expansion rate similar to copper.
Q. What kind of warranty
is offered?
A.
Viega offers a 10-year warranty
on the PureFlow system
covering replacement, property
damage and reasonable repair
costs. The warranty can be
transferred to future owners of
your home during the 10-year
warranty period.
