It is critical that the boiler water pH be
alkaline in the range 10.0 - 12.0.
Daily boiler blowdown is essential to
help prevent formation of deposits
and reduce Total Dissolved Solids
(TDS).
Consult your water treatment specialist
to establish the frequency and duration
of blowdown required to achieve the
required conditions.
