p2 p.What spe shows will work fine. If u run a file across the threads to remove the sharp edge as the pipe is designed to go into the fitting.This fitting in the link would go straight onto the thread and you fit a hoselock fitting on that. When you remove the hose you will need a blanking plug or a hoelock connector with an isolator on it.Andyhttp://www.hozelock.com/watering/hose-fittings/connect-to-tap/2041-pro-metal-3-4-tap-connector-adaptor.htmlThis would go straight in your tank and you can use a backnut from a bath tap with 3/4 " thread. b an q will sell them or your local plumbers. Again you will need to block it up when travelling. http://www.hozelock.com/watering/hose-fittings/connect-to-hose/flat-hose-spiral-hose-adaptor-2170.htmlSPE. Looking again at your pictures your idea wouldn't work actually because the bib tap has a male thread as does the tank fitting you show.
