What’s worst than signs of a single in-ground oil tank? Thinking that there might be two in-ground oil tanks at the same property! I was beside myself as I saw this sight on the way into the home. Fortunately, once we got to the lower level we could see that there was actually basement space under the front porch (very unusual) and that these pipes fed the two tanks in that space. Whew!
A quality venting job for sure.
