how to stop a slight leak between shut off valve on oil tank and the supply line

[jonnystewart]

Hi,

There is a slight drip/leak between the shut off valve on my oil tank and the supply line. What is the best way to seal this?

Thanks

Jonny

I would advise getting an oftec engineer in as if you muck up you will destroy your garden. Plus insurance wouldn't pay.

something like that should be picked up when you get the boiler serviced

Do ya reckon supper plumb would have had this covered by now with his "One cure" solution?
What did he get banned for?
