6. Bundles can be supported with hangers designed for larger tubing
sizes.
7. The nylon ties can be used to support PEX lines directly from wooden
framing members.
Any plastic cable ties capable of supporting the weight of the tube or
bundle when 󶈵lled with water can be used.
8. Holes drilled through studs, joists, plates, headers, etc., must be large
enough to accommodate tubing bundles without binding to allow free
movement. Several smaller holes (accommodating a few lines each)
may be preferable to drilling a bundle-size hole. In no case should the
hole size exceed building code guidelines, as this could weaken the
structural support members.
For more detailed instructions, refer to "11 Installing the Viega PureFlow
PEX Tubing System" on page 58
CAUTION!
DO NOT USE DUCT TAPE FOR BUNDLING. Duct tape will
not permit tubing movement.
10.2 Valve Operation
A ManaBloc system, which has valves on all of the outlet ports, does
not require stop valves at the 󶈵xtures. However, the Authority Having
Jurisdiction (AHJ) may require stop valves at some 󶈵xtures.
Use the included red key handle to turn each port ON or OFF. Valves are
marked with arrows indicating their ON/OFF positions:
Left Port: Arrow Up for OFF
Arrow Left for ON
Right Port: Arrow Down for OFF
Arrow Right for ON
These valves are 󶈵eld-repairable. Contact Viega Customer
Service for more information on this procedure.
