Replacing a worn-out tank
Tank leaking, rusty water or past ten years old? Get it replaced with the right size before it floods the garage or attic.
Signs
These signs usually mean the tank is finished:
Most tanks give about 8 to 12 years of service. Planning the swap before a leak is cheaper and calmer than an emergency.
Same or switch
The simplest replacement is the same fuel and size in the same spot. Switching from gas to electric, going up a size, or moving to tankless adds work: a gas line, a circuit, new venting or a new location.
For many homes in Houston, TX, a switch is worth pricing if you run out of hot water often, need the floor space, or plan to stay long enough for a tankless unit's longer life to pay off.
The job
Turn off gas or power and water, then drain the old tank.
Disconnect and carry it out, including from attics.
New connectors, shutoff, relief valve and discharge line, plus venting for gas.
Drain pan, expansion tank or a raised stand where required.
Fill, light or power up, check for leaks, and schedule the City inspection.
Old tank rusting at the base? Replace it before it lets go.

On a tank under about 8 years old with no leaks, replacing a worn anode rod can buy years. Once the tank itself leaks, it is too late; water heater replacement is the only fix.
Price
Typical installed prices: about $1,100 to $1,500 for a 40-gallon gas tank, $1,300 to $1,900 for a 50-gallon gas tank, $1,100 to $1,400 for a 40-gallon electric tank and $1,300 to $1,800 for a 50-gallon electric tank. Attic access, venting changes and code items add to that.
