WATER SUPPLIES 

 

This  water  heater  must  be  installed  in  accordance  with  this  advice  to  be  covered  by  the  Everhot 
warranty. 

 
This  water  heater  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 water heater 
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 Everhot warranty to apply. 
 

CHANGE OF WATER SUPPLY 

The changing or alternating from one water supply to another can have a detrimental effect on the operation 
and / or life expectation of a water heater cylinder and a temperature pressure relief valve. 
 
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  information  should  be  sought from  the supplier  or  it  should  be tested to  ensure  the  water supply 
meets the requirements given in these guidelines for the Everhot warranty to apply. 
 

ANODE 

The vitreous enamel lined cylinder of the water heater is only covered by the Everhot warranty when the total 
dissolved solids (TDS) content in the water is less than 2500 mg/L and when the correct colour coded anode 
is used. If an incorrect colour coded anode is used in the water heater, any resultant faults will not be covered 
by the Everhot warranty. In addition, the use of an incorrect colour coded anode may shorten the life of the 
water heater cylinder. 
 
The correct colour coded anode must be selected and fitted to the water heater in accordance with the following 
advice and th

Anode Selection chart

The changing of anodes must be carried out by a qualified person. 
 

Note:

  Some  water  analysis  reports  may  state  the  conductivity  of  the  water  rather  than  the  level  of  total 

dissolved solids. Conductivity, measured in microsiemens per centimetre (

the TDS content of the water. TDS, in mg / L, is approximately 70% of the conductivity in
