Pool/Spa Water Chemistry
pH of Water
pH is a measure of relative acidity, neutrality or alka-
linity. Dissolved minerals and gases affect water’s pH.
The pH scale ranges from 0 to 14. Water with a pH of
7.0 is considered neutral. Water with a pH lower than
7 is considered acidic. Water with a pH higher than 7
is considered alkaline. A neutral pH (around 7) is desir-
able for most potable water applications. Corrosion
damage and water heater failures resulting from water
pH levels of lower than 6 or higher than 8 are non-war-
rantable. The ideal pH range for water used in a
storage tank or a copper water heater system is 7.2 to
7.8.
Total Dissolved Solids
Total dissolved solids (TDS) is the measure of all min-
erals and solids that are dissolved in the water. The
concentration of total dissolved solids is usually ex-
pressed in parts per million (ppm) as measured in a
water sample. Water with a high TDS concentration
will greatly accelerate lime and scale formation in the
hot water system. Most high TDS concentrations will
precipitate out of the water when heated. This can
NOTE: Chemical imbalance can cause severe
damage to your heater and associated equipment.

generate a scale accumulation on the heat transfer
surface that will greatly reduce the service life of a pool
heater. This scale accumulation can also impede ade-
quate flow of water and may totally block the water
passages in the tubes of the heat exchanger. A heat
exchanger that is damaged or blocked by lime/scale
accumulation must be replaced. Failure of a water
heater due to lime scale build up on the heating sur-
face is non-warrantable. The manufacturer of the pool
heater has no control of the water quality, especially
the TDS levels in your system. Total dissolved solids in
excess of 1,500 ppm will accelerate lime and scale for-
mation in the heat exchanger. Heat exchanger failure
due to total dissolved solids in excess of 1,500 ppm is
a non-warrantable condition.
NOTE: The allowable concentrations of salt and of the Total Dissolved Solids are lower for the Hi Delta than
for a typical residential pool heater, due to the higher water temperatures at which a Hi Delta operates.

scale build-up on the heating surface, low pH or
other chemical imbalance is non-warrantable.
