Normal Operation 
It is normal and desirable that this 
valve allows a small quantity of 
water to escape during the heating 
cycle. However, if the discharge is 
deemed excessive (more than 2% 
of hot water used), 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 9). 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 water heater is cold - then stops until 
water reheats 
The water heater must be switched off at the switchboard. Phone your 
nearest Rheem Service Department or Accredited Service Agent to arrange 
for an inspection. 

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

(refer to page 

25

)

 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.
