Hi as above really, I noticed last night we had a slight leak, so shut off at the in-line connector, undone the nut that's connected to the bottom of the cistern noticed the plastic thread has gone to shot and whoever connected up before, used loads of that thin plasticy tape (i mean loads), I take it all i need to do is get one of: http://www.screwfix.com/prods/55211.../Adjustable-Height-Bottom-Entry-Torbeck-Valve and re-connect backup?
