If your looking at this page something is wrong with your water heater and your are wondering if it can be fixed. Well,
sometimes yes and sometimes no. Below I will outline the different things that can go wrong with a water heater and
what we can do to fix it.
#1 most common call I get is the pilot light went out and you can't relight it or you
get it re lit and it will only run one burn cycle and then go out again.
This little device is called a thermal coupler and it's most likely the
cause of your problem. The thermal coupler tip is in contact with the
pilot light, the heat from the pilot light creates a small amount of voltage
allowing the valves in the gas control valve to work allowing the main
burner to kick off and heat water. Thermal couplers have what I call a
mystery life span, 18 months to 15 years. There a few units out there
that we don't work on so before you call me please have the name of
the company that made the heater and the model and serial number off
of the unit. $250 to $300 is the typical service fee to replace this part.
#2 most common call I get. My water heater just doesn't make the same quantity or quality hot water
like it used to. Or the water heater will go out every two to three days and the thermal coupler has
already been replaced. The part in question is called the Gas Control Valve or thermostat. This device
not only reads the current temperature of the water but it also regulates when the burner turns on and
off and controls gas flow.
Two things happen to this device that causes problems, first over a period of time small amounts of
dust will get stuck on the moving parts inside of the unit and causing it to not function correctly. This is
why it will work for a few days then not work. The second problem is mineral deposits will collect on the
copper shaft that goes inside of the tank. If enough deposits collect on the shaft the unit will not be able
to accurately read the temperature of the water causing the water to become hot and then cold or not
hold temperature at all.
If your water heater is over 10 years old and this part needs to be replaced I strongly recommend that
you replace your water heater. Trying to find this part on units that are 10 years old or older can be very
difficult and they can be very expensive. So why spend a bunch of money on a part for your water heater
when it could start leaking tomorrow. Average cost to replace this part ranges from $400 to $700
Also there are some makes and models out there that this issue is common and a real problem. On
some makes and models the parts are very difficult to find and a replacement of the heater is advisable.
#3 most common call. My water heater is leaking, can you come and fix it? Unless you see
water on top of the heater and the leak is from a pipe or a connector you are most likely
looking at a replacement situation. Call me or go to the New Water Heater section on this

not work on and they are listed below.
