|In response to Re: Converting an old water heater tank to air pressure.|
: It should work, although an air pressure tank is supposed to be ASME rated, because of the danger in the event of a rupture.
: : Hello, I replaced my 20 year old 40G gas water heater. The old one was not leaking, I just wanted something more efficient. I would like to use the old tank as a pressure tank for a compressor I am building. I have the pump which is currently attached to a 10 gallon tank but would like to upgrade to a 40 gallon tank. An old water heater tank seems like it will work. I removed the outer jacket and insulation from the steel tank. I would be pumping air into this tank to a maximum pressure of 110 PSI. Since a T&P valve is rated higher that that, I figured that my project would work. Do you have any thoughts or suggestions on my idea?

The pressure that your hot water tanks is rated at is about 30 psig. After 20 years you have not idea what condition the tank is in. I think you'll find the tank will repture or explode. NOT a good idea.
