"I came home to find my heating oil tank leaking"

A real "it won't happen to me" but I knew I could smell something from the garden so went to have a look. I found it pouring out like a little tap! I panicked; I had over 1000 litres in there and I know that kerosene kills plants and can get into the foundations of the house.

So grateful I remembered I had a tub of Dammit in the shed and honestly couldn't believe how quickly it worked. I just pushed it onto the hole and it stopped straight away. The guy that brought the new tank said I'd have lost the whole lot into the ground otherwise! I won't be without it now, it's not worth the risk.
