I will be replacing the legs on my home heating oil tank. It's 275 gallons and located in my basement. The legs are rusted badly, one missing the bottom 2". The tank is leaning on a cast iron soil pipe against a wall. Is there an easy way to do this? A verbal quote from a contractor was "about $200". Here are my plans: Make 1 or 2 jacks out of angle iron, all-thread, nuts and bolts to attach to the leg brackets. The leg brackets already have 2 holes in each. Wait until it is 1/4 full. Shut off the heater, close the valve on the tank. Jack up the tank. Remove old rusty legs.(I hope they come out easily) Install new legs. Legs on valve end 1" shorter than the other end.
Any other ideas or suggestions? Thanks, MikeH
