valve. Where possible this should be installed through an outside wall
like a cistern overflow, where it will give a visual indication of any failure.
4.1.2 Operating Space
The space occupied by the softener can be found in the Engineering Data
(Section 11.2).
Access will be required to refill the salt tank, and to carry out
adjustments or maintenance on the equipment. It is therefore
recommended that a minimum of 500mm clearance be allowed in front of
the unit for this purpose.
4.1.3 Incoming Water
The raw water to be fed to the softener must comply with the
following:-
1. Available at all times at a flow equal to or greater than
the required service flow
2. At a pressure between 1.7 and 8.0 bar
3. Temperature between 4 and 38
o
C
4. Suspended solids less than 1 ppm
5. Iron less than 0.2 ppm, Manganese less than 0.1 ppm,
Free Chlorine less than 1 ppm if temperature is less than
15oC, less than 0.3 ppm if temperature higher (up to 30oC)
4.1.4 Pipework
Pipework to be connected to the softener should not have an
excessive amount of hardness scale deposit. Piping that is heavily built up
with scale (or Iron deposits) should be replaced.
Make sure that the pipework can be connected to the softener in such a
way as to impose no stresses on the control valve, and that it is properly
aligned and supported.
A system for the complete by-passing and isolation of the softener should
be installed.
4.1.5 Water Supply Company Requirements
It is essential that if the equipment is to be connected directly to a mains
water supply, the local bylaws must be adhered to. These cover both
plumbing and the prevention of backflow into the mains. If there is any
doubt, the local water inspector should be consulted, but in general, the
installation of a 'Double check valve assembly' conforming to BS6282 part 2
will be required in the feed pipework to the softener.

necessary to install a booster pump arrangement. Such a system would
