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
dislodge a small particle of foreign
matter and rectify the fault.
Steady ow (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.
