there are differences in pressure or flow rate the cause of this imbalance must be found in
between the hot and cold water system the system.
For example: a non-return valve may be
jammed or secondary offtakes may be
reducing the flow rate in the pipes to the
mixer or a water softener may have been
fitted to the mixer circuit rather than at the
main cold water inlet
