Unsure how to stop a leak.

You could use Thomas Dudley Hydroflo float valve with brass tail.

It's not the pipework that's short, it has dropped down. The original post with the picture, shows cross threaded float valve.

All done are sorted now. Thanks everyone for the help.

Went with the new Fluidmaster valve and some jointing compound on the washer. All seems good, no leaks
