Replacing Water Heaters
The most common types of water heaters
include natural gas, LP-gas, and electric water heaters.
Among many other household plumbing projects, replacing
your water heater is one that you will have to face at some
point or another. Generally, water heaters reveal signs
of replacement in the form of a leak. This usually means
that your tank is corroded. The replacement process requires
much knowledge and skill and is often a job suited for a
service professional.
The first step in replacing your water
heater is to remove your old water heater. You should begin
this process by shutting off the gas or electricity to your
old heater. With electric water heaters, simply shutting
of the electricity does not guarantee that the wires will
be dead. Make sure to test the wires for electric power
before touching them.
The next step is to drain the water from
the heater. This water may be very hot so use caution when
draining. Keep in mind, the cold water pipe of your heater
will most likely have a shutoff valve. Using this valve
will allow the water heater to be disconnected without shutting
down the entire home's water supply.
Once the water is drained, you will then
be able to remove the heater. Gas heaters require you to
separate the vent pipe from the draft hood and disconnect
the gas line before removal. Also, as mentioned earlier,
verify that the wires are dead on electric water heaters.
Only then will it be safe to disconnect the cable wires
and remove the heater.
Once your old heater is removed, you will
be required to transfer a new heater to its place. This
may require the use of a dolly or some sort of a cart. After
the heater is positioned, you will need to install the new
heaters draft hood. In addition, make sure with gas water
heaters that you install proper venting. After the vent
piping is connected, you can begin to make hot and cold
water connections.
*When installing a new gas heater, make
sure that the gas you have is compatible with your new heater.
Also, view the heaters owner manual to verify that the combustion
needs will be met, as well any required clearances. Once
installed, make sure to check for leaks with a dish detergent
solution.
