Normal Operation 
It is normal and desirable this valve 
allows a small quantity of water to 
escape during the heating cycle. 
However, if it discharges more than 
a bucket full of water in 24 hours, 
there may be another problem. 

• 

Continuous dribble 
Try gently raising the easing lever 
on the relief valve for a few seconds 
(refer to 

“Temperature Pressure 

Relief Valve”

 on page 8). This may 

dislodge a small particle of foreign 
matter and clear the fault. Release 
the lever gently. 

• 

Steady flows for long period 
(often at night) 
This may indicate the mains water 
pressure sometimes rises above the 
designed pressure of the water 
heater. Ask your installing plumber 
to fit a pressure limiting valve. 
 
NEVER replace the relief valve with one of a higher pressure rating. 

• 

Heavy flows of hot water until the water heater is cold - then stops 
until water reheats 
The gas control must be turned off using the knob on top of the gas control 
thermostat (refer to 

“Close Down Procedure”

 on page 27). Phone your 

nearest Rheem Service Department or Accredited Service Agent to arrange 
for inspection. 

 
EXPANSION CONTROL VALVE RUNNING 
If an expansion control valve is fitted in the cold water line to the water heater 

(refer to page 

20

)

 it may discharge a small quantity of water instead of the 

temperature pressure relief valve on the water heater. The benefit is that 
energy is conserved as the discharged water is cooler.
