Troubleshooting
What Should I Check Before
Making A Service Call?
If there is not enough hot water, it is
recommended that the following points
be considered before making a service
call. If after checking the following points
the problem has not been identified,
please contact Dux on 1300 365 115.
No Hot Water
• Is the Pressure & Temperature Relief
Valve discharging too much water?
• Do you have the correct size water
heater for your requirements? Sizing
details are available from your Dux
supplier.
• Is one outlet (such as the shower)
using more hot water than you think?
• Carefully review the family's hot
water usage and if necessary check
the shower flow rates with a bucket,
measuring the amount of water
used over that period of time. If it is
not possible to adjust water usage
patterns, an inexpensive flow control
valve can easily be fitted to the
shower outlet.
• Consider that often the hot water
usage of showers, washing
machines and dishwashers can
be under estimated. Review these
appliances to determine if your
daily usage is greater than the
storage volume of your water
heater. For example, if you have
a 315 litre storage tank and you
are using 450 litres of water it is
possible that there will be certain
times of the day where there is
insufficient hot water. It is also
advisable to inspect tap washers
etc. for leakage and replace if
necessary.
• Is there a leaking hot water pipe or
dripping hot water tap? A small leak
can waste a large quantity of hot
water.
• Replace faulty tap washers and have
your plumber rectify any leaking pipe
work.
Water Discharge From Pressure &
Temperature Relief Valve (PTR)
It is not unusual for a small quantity of
water to discharge during the heating of
water in your storage tank. The amount
of discharge will depend on hot water
usage and size of the storage tank.
As a guide, it will discharge 3% of the
storage capacity of water in the heating
period.
Continuous Trickle (PTR)
This is most likely due to a build up of
foreign matter. In this case, try gently
raising the easing lever on the PTR Valve
for a few seconds, then release gently.
This may dislodge a small particle of
foreign matter and rectify the fault.
