I've got a Tigerloop installed in my oil central heating system. Walked past it this morning and got a whiff of oil so took a closer look to find that I have oil on the ground, and running down the pipe from the tigerloop. I also have oil marks on my house wall which resemble that of spinning liquid.
I'm kind of new to the whole DIY thing, and never installed the tigerloop or even really know what it's there for.
Has anyone else experenced this sort of thing?
