I am the proud owner of an empty home heating oil tank and I need to drop in a few gallons of diesel to tide me over till tomorrow’s delivery.
The problem is I have two pipes sticking up next to each other with no indication which is the fill pipe and which is the vent pipe.
Pipe A is a 2 inch pipe with a cap loosely screwed on.
Pipe B is a 1.5 inch pipe with an over-sized cap placed on top. Only gravity is keeping the cap in place. If I follow Pipe B to the tank, the Empty/Full valve thingy is attached where Pipe B goes into the tank.
So… which pipe is which? And what will happen if I pour diesel down the vent pipe by accident?
Any guidance would be appreciated as I’d like to fill this thing before the pilot light goes out. Thanks in advance!
Thanks, everyone. I put the diesel in the 2" pipe and everything seems to be going fine.
Xema, thanks for that info. You can tell I’m not all that familiar with oil heat. I guess that’s another reason my heat doesn’t work when the power is out.
Aceplace57, the smaller pipe has a loose cap on it, I guess to keep out rain. I’m pretty sure the guy takes it off when he is filling the tank. It would be pretty apparent if the tank starts leaking as it would be all over the basement.
