4.5.6. Water supply line and bypass connections
4.5.6.1 Water supply line
The connections should be hand tightened using PTFE (plumber’s tape) on the threads if using the
threaded connection type.
In case of heat welding (metal type connection), the connections should not be made to the valve when
soldering.
NOTE

See chapter 3.1.2. System service & regeneration cycles (8-cycles operation), page 14 to
identify the connections.
When pressurized, any composite tank will expand both vertically and circumferential. In order to
compensate the vertical expansion, the piping connections to the valve must be flexible enough to
avoid overstress on the valve and tank.
In addition, the valve and tank should not be supporting any part of the piping weight. This is hence
compulsory to have the piping fixed to a rigid structure (e.g. frame, skid, wall…) so that the weight of
it is not applying any stress on the valve and tank.
