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
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. 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.
