APPENDIX B
The size of the distribution pipes supplying
the manifold should be calculated using
the method set out in BS 6700. A typical
diagrammatic arrangement of a system using
Manifold Type 1 is shown below. This is only
meant to show the principles involved and the
actual connection of fittings to the manifold
will need to suit the arrangements shown on
page 35.
Note 1 - If it is proposed to fit chemical water
treatment such as a water softener this should
be fitted in this location and the cold water
branch in the sink should be branched off the
cold water main prior to the treatment device
instead of the cold water manifold.
Any other isolating/control valves and
backflow protection devices should be
provided as necessary to comply with the
Water Regulations.
