2 pipe oil

nick z.

Underground oil tank, 2 pipe oil system. the house had a fire and G.C. removed the old boiler. Now I have 2 capped off lines and no way to know which was the feed and which was the return. I realize if both lines go to the bottom it won't matter which is which. Does anybody have a good way to identify which one is which? Thanx

Better safe than sorry!

I would dig them up and replace w/new feed line and use a "Tigerloop" and avoid the use of a return line. Most oil leaks are from return lines than anything else. I'm sure this is not what you wanted to hear, but remember once you touch it you own it.Better safe than sorry!P.S. use a covered oil line. John@Reliable

With Co2 or soda charges and a blow gun. You can blow the lines while someone listens into the stick well. Bubbles will be a deep one & the one that sounds like a race-horse pissing than farting is the high one (return). If you here nothing from one of them and its an old tank you mite have found a foot valve ( check valve at the bottom of the tank), then you will need an old timmer with a draw pump or a youngster with a shovel. good luck

in maine, underground residental oil tanks have been banned. i can only guess that it was because they problems with them. you may want to remove your underground tank.
