5. MY WATER HEATER IS LEAKING FROM
THE TOP. WHAT SHOULD I DO?
• Some issues are self reparable while others may require
a professional.
• Possible issues:
• A loose valve – if there is water around the valve, you can drain
the unit and tighten it. If there is rust or damage, you will need to
replace it.
• A loose pipe fitting – tighten the loose pipe with a wrench.
Extremely loose pipes have risk of bursting.
• Rust or corrosion – older tanks may need to be replaced.

7. MY WATER HEATER STOPPED
WORKING. WHAT SHOULD I DO?
• See if the problem is okay to fix yourself or if it requires a
professional.
• Some potential reasons include:
• The pilot light is not lit – check the owner’s manual for
instructions
• Bad heating element – this will need to be replaced by a
professional
• Sediment buildup – drain and flush the unit once a year to
reduce sediment build up
• Bad thermostat – adjust the thermostat or it may need a
replacement
• Gas leak – a “rotten egg” smell is an emergency. call a
professional.

8. HOW DO YOU TROUBLESHOOT AN
ELECTRIC WATER HEATER?
• A couple different problems that you can check first
before calling a professional are:
• No hot water – check to see if the unit is getting power. Hit the
reset button.
• Not enough hot water – Temperature may be set too low on the
thermostat.
• Water is too hot – Make sure the thermostat fits snugly on the
tank or lower the water temperature.

9. HOW DO YOU TROUBLESHOOT A
GAS WATER HEATER?
• Most gas heaters are reliable but here are some
problems you may be able to troubleshoot yourself.
• Pilot light will no stay lit – Make sure there has been no service
interruption with your gas provider. Try cleaning the burner or
bleeding the air from the line.
• Not enough hot water – the unit may simple be too small. Try
turning up the thermostat and drain and flush the tank to remove
sediment.
• The thermostat does not shut off – Contact a professional
because this is likely a calibration problem.

10. HOW DO YOU TROUBLESHOOT A
TANKLESS WATER HEATER?
• Most tankless water heaters can last up to 20-25 years.
Some problems that you may run into are:
• Lack of hot water – If the standby light isn’t on, that means no
power is getting to your unit. Make sure the breaker hasn’t
tripped.
• Clicking noise – This is normal and there is no need to worry.
Move the unit farther away or into the garage if it becomes
annoying.
• Flickering lights – the electrical panel may be too old or too
small. Check with a professional to make sure that your panel has
sufficient amp capacity.

11. WHAT SIZE WATER HEATER DO I
NEED?
• If your tank is too small, you may run out of water too
often and conversely, if it’s too large, you may be wasting
money.
• Allot 12 gallons of hot water for each bedroom plus one
in your home.
 Back to menu

12. GAS VS. WATER HEATER
DIFFERENCES?
• Electric units cost more to purchase install and operate.
• Gas units last 13 years while electrical units last about
12 years on average.
• Gas units are less efficient because of heat loss.
However, it can be helped with proper insulation and
maintenance.
• Gas units have a much faster recovery rate than electric
units meaning it will take much less time to reheat water.
• Gas units will continue to work in a power outage.
