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 Pressure
& Temperature Relief 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 Pressure &
Temperature Relief Valve or a faulty
thermostat. Turn off the electricity supply
and contact your Dux Hot Water.
