I was just walking around my yard and noticed that the cap was off my heating oil tank. I don't know how long it's been off but we had some rain the past couple days. Should I be worried about water getting in, and if so How would I check if there's water in there and what do I do about it?
It should settle to the bottom. If the tank is in your house - you should be able to let it sit a while and then drain it until you hit oil using the petcock near the filter housing. If not... you can use a hand pump and a bit of tubing from home depot from the fill neck.
There is some goo you can buy to test for water that you put on the end of your dipstick (heh, heh) but I forget what it's called.
The pump suction line coming off the tank is well enough above tank bottom that it should be no issue. There is always some water in the tank just from tank condensation as well as their storage tanks and how much rain can get in through a 2" pipe anyhow. Wouldn't worry about it.
In reply to fasted58:
I was hoping there would be a lazy way out. Thank you.
Another option is something like this:

Drops in the tank to absorb the water but not fuel.
Does your tank have a bleeder on the bottom?
