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
fi ttings to the manifold will need to suit the
arrangements shown on page 35.
Note 1 - If it is proposed to fi t chemical water
treatment such as a water softener this should
be fi tted 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.
