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.
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.
Steady Flow (PTR) – More than
20L per day
This may be caused by excessive water
supply pressure, a faulty PTR Valve or a
faulty thermostat. Contact Dux
on 1300
365 115.
Insufficient 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 170 litre
storage tank and you are using
300 litres of water it is possible that
there will be certain times of the day
where there is insufficient hot water.
• Is there a leaking hot water pipe or
dripping hot water tap? A small leak
can waste a large quantity of hot
water.
