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

(refer to page 

22

)

 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. 
 
CAN’T LIGHT THE PILOT FLAME 

• 

Is there gas to the water heater? 
Check the gas isolation valve on the gas 
supply line is open. 

• 

Is there a normal gas supply to the rest 
of the premises? 
Try lighting another gas appliance to check. 
If there is no gas, call the gas supplier. 

 
WATER HEATER APPEARS TO BE LEAKING 
When the water heater is first lit, or after a large usage of hot water, 
condensation may form on the burner of the water heater. This is quite normal, 
especially in winter months and will dry off as the water is heated. 
 
HIGH GAS BILLS 
Should you at any time, feel your gas account is too high, we suggest you 
check the following points: 

• 

Is the relief valve running excessively? 
(Refer to 

• 

Is one outlet (especially the shower) using 
more hot water than you think? (Refer to 

“Not Enough Hot Water”

 on page 11). 

• 

Is there a leaking hot water pipe, dripping 
hot water tap, etc? Even a small leak will 
waste a surprising quantity of hot water and 
gas. Replace faulty tap washers, and have 
your plumber rectify any leaking pipe work. 

• 

Consider recent changes to your hot water usage pattern and check if there 
has been any increase in tariffs since your previous account.
