9.1 Pressure & Temperature Relief Valve Running
It is normal for the Pressure & Temperature Relief valve to discharge a small quantity of water
during the heating cycle. The amount of discharge will depend on hot water usage. As a guide, if
it discharges more than 20 litres of water in 24 hours then there may be a problem. Check with
your plumber or SIDDONS.
9.1a Continuous Trickle
Likely cause is a build up of foreign matter. Try gently operating the release mechanism on the
Pressure & Temperature Relief valve for a few seconds. This may dislodge any small particles
of foreign matter and rectify the fault.
9.1b Steady Flow
Likely causes are excessive water supply pressure (500kPa Pressure Limiting valve should be
fitted), a faulty Pressure & Temperature Relief valve, a faulty or non-existent pressure limiting
valve or a faulty Thermostat / Digital Controller. Turn off the electricity supply and contact your
plumber or SIDDONS.
9.2 No Hot Water
1) Is the Electricity switched on? Check that the isolating switch on the cold water supply to the
hot water storage tank is open. Check that the switch marked Water Heater on the switchboard
is turned on. Are all circuit breakers on? If your Solarstream is connected to Off Peak, is the
meter switching on when it should?
2) Check that the thermal overload (on the digital controller) has not tripped. Turn the power
off then back on to perform a reset.
3) Is the Pressure & Temperature Relief valve discharging too much water? Refer section
.
4) Do you have the correct size water heater for your requirements? Sizing details are available
from your Dealer or SIDDONS.
5) Is one outlet (such as the shower) using more hot water than you think? Carefully review your
family's hot water usage and if necessary check the shower flow rates with a bucket and watch.
If it is not possible to adjust water usage patterns, we recommend you fit a flow control valve to
the shower head.
