11 Installing the Viega PureFlow PEX Tubing System
The properties of Viega PureFlow PEX tubing make it easy to work with
and install in most types of construction. Some care must be taken to
prevent damage to the tubing before and during installation:
■ Use care to protect Viega PureFlow PEX tubing from physical damage
during storage and installation. Keep the tubing away from sharp
objects, open 󶈶ames, etc., and do not place heavy objects on the tubing.
■ Damaged sections of tubing should be cut out and discarded.
■ Do not expose Viega PureFlow PEX tubing to sunlight or any UV
source for extended periods of time exceeding six months.
■ Do not store Viega PureFlow PEX tubing outdoors where it may be
exposed to UV light.
11.1 Handling PureFlow PEX Tubing
11.2 Decoiling PureFlow PEX Tubing
A decoiler should be used to prevent twisting when removing tubing from
¾" to 1" coils. Roll coils out and use care to avoid twisting 1¼", 1½", and
2" coils or when a decoiler is unavailable. If larger diameter tubing is used
for short run sections, straight lengths are also available which can assist
in this type of installation.
