I need advice on what to do with my buried oil tank.
I have a 1000 gal buried oil tank that was installed when the house was built in 1987. We bought the house in '95. The house is a slab house so we have no basement for a tank to be placed. The tank was installed with a 15 year anode.
I like having a big tank because I get substantial discounts when I make my annual oil purchase. We use about 750 gallons/year.
Because the time period for the anode is more than over, I wanted to be responsible by replacing the tank. Of course the new tanks are double walled, fiberglass, with double walled flexible lines coming into the house, and with monitoring capability.
I haven't yet gotten the proposal for the job of replacement but I know it's not going to be small. While I'm waiting for the estimate, I asked them for a breakout 3 different ways: 1. I want to know the cost for 1000 vs 2000 gallons. If I can fill up once every two years, the price will decrease even more substantially. 2. I want to know the cost of placing the new tank in the ground covered in peastone, vs putting it in its own underground house, i.e., floor, four walls, and a roof cover. 3. I want to find out the cost of an automatic monitoring system vs the cost of a manual monitoring system. The automatic systems check for leaks and provide for notification. If it's allowed I want to see if a manual system can be allowed by my town.
Those three questions should yield six different costs. Then in addition, it occurs to me that I should also be able to dig up the top of the old tank and see about simply replacing the anode.
So that's my story, and I'd really like to get people's feedback on what sort of thoughts people have. What should I do? Is it crazy to talk about just anode replacement? Is the 2000 gal tank a mistake?
I appreciate your input.
