Leaking toilet

[jay888]

Hi,
Hope you can help.
I have a leak from my toilet supply pipe (above the cut-off valve.
I have turned the supply valve off and drained the tank.
There's still a little water in the tank, but the pipe is now dry. I'm guessing that rules-out the seal washer inside the tank as the issue?
Should I just buy a replacement supply value? Any advice would be really appreciated.
Jay.

If the leak is directly above the nut of the isolator valve, you need a new fibre washer in there......or, it may nip up a little.
The fill valve often has a rubber taper plug on the inside of the cistern - these don't tend to leak if the white plastic nut is tight.
