4.2 Water Quality
The SunSiphon system is manufactured to suit the
water conditions of most public reticulated water
supplies. However, there are some known water
chemistries which can have detrimental effects on
the system and its operation and/or life expectancy.
If you are unsure of your water chemistry, you may
be able to obtain information from your local water
supply authority. This water heater should only be
connected to a water supply which complies with
these guidelines for the warranty to apply.
The changing or alternating from one water sup-
ply to another can have a detrimental effect on the
operation and / or life expectation of the system and
its components. Where there is a changeover from
one water supply to another, e.g., a rainwater tank
supply, bore water supply, desalinated water supply,
public reticulated water supply or water brought in
from another supply, then water chemistry informa-
tion should be sought from the supplier or it should
be tested to ensure the water supply meets the
requirements given in these guidelines for warranty
to apply.
4.2.1 CHLORIDE AND PH
In a high chloride water supply, the water can cor-
rode stainless steel parts and cause them to fail.
Where the chloride level exceeds 250 mg/L war-
ranty does not apply to the stainless steel tank or a
heat exchanger in a GX indirect system. SunSiphon
systems shall not be installed where chloride levels
exceed 250 mg/L.
pH is a measure of whether the water is alkaline or
acid. In an acidic water supply, the water can attack
stainless steel parts and cause them to fail. Where
the pH is less than 6.0 no warranty applies to a
stainless steel cylinder or a heat exchanger in a GX
indirect system. Water with a pH less than 6.0 must
be treated to raise the pH above 6.0.
