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 during night time
heating, the time taken to heat
the tank can take longer so you
may find that the tank has not fully
recovered from a period of heavy
usage the previous evening.
•
Consider that often the hot water

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 the PTR
Valve
Pressure & Temperature Relief Valve
(PTR)
It is normal for the PTR to allow a small
quantity of water to escape during the
heating cycle. The amount of discharge
will depend on hot water usage.
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 Pressure
& Temperature Relief Valve for a few
seconds then release gently. This may
