UNDER NO CIRCUMSTANCES shall any form of thread sealant
(Te󶈶on
®
paste, pipe dope, etc.) be used on distribution line
connections. The carriers present in these compounds can
crack the plastic port connections, resulting in leaks and water
damage.
Hand-tighten only. Damage may result if over-tightened.
10.4 Connecting Distribution Lines to Fixtures
There are a variety of male and female adapters, sweat adapters, turn
out supports, and stub out adapters to assist in terminating at the 󶈵xture
(refer to "13 Installing Viega PureFlow Fittings" on page 73 or the Viega
product catalog).
The main water supply shall be turned o󶈴 before making water supply
connections.
The ManaBloc water supply connection uses a special 1" swivel
ManaBloc transition 󶈵tting that seals with a sealing element.
This connection is used on the cold water supply and the hot water
supply/return lines. This connection to the ManaBloc does not require any
form of thread sealant and none shall be used.
DO NOT USE ANY FORM OF THREAD SEALANT TO MAKE THIS
CONNECTION
Water service connections to adapt to most types of plumbing
supply materials are available. Consult the Viega Product
Catalog for a complete listing of available connections.
1. Connect water service adapters to water supply piping before
attaching the swivel 󶈵tting to the ManaBloc (instructions included
with adapters). Excessive force from threaded 󶈵ttings or solvents from
solvent welding (PVC or CPVC) will cause damage to the ManaBloc.
Drill all holes in wood members for water supply/return tubing
BEFORE mounting the ManaBloc.
2. When using male or female pipe thread transition 󶈵ttings, to connect
to supply tubing, use only Te󶈶on tape to seal pipe threads. DO NOT
use pipe dopes, thread sealers, Te󶈶on pastes, etc.
