I cannot, for the life of me, get the one I currently have to sit on this flippin' tap properly & either I end up soaked trying to get water in the paddling pool or dd2 ends up with a trickle from the hose & I end up with a steady flow back up into the sink 
It's doing my bloody nut in.
The girls dad needs to go to town tomorrow so I'll send him to Wilko for whatever it is I need (and hopefully they'll be in stock!)
