Water Quality
Water quality outside the limits (as set down below) will void this warranty. Water quality tests
must be carried out at the customer's own cost but Rinnai will reimburse any reasonable test
costs where water quality is within the limits tabled.
Water Quality and Impurity Limits
TdS (Total dissolved Solids)
Up to 600 mg/L or ppm
Most metropolitan water supplies fall within these limits. If you are unsure about water quality,
please contact Rinnai and we will provide you with the details of an authorised agency able to
test your water for compliance to Rinnai standards. If sludge or foreign matter is present in
the water supply, a suitable filter should be incorporated in the water supply.
Some examples of water quality issues where water may need to be treated:
• Hard water (areas including Wanganui)
• aggressive water (areas including Christchurch)
• Both hard and aggressive water (some bore water)
