Water Change, Like A Military Excercise

I've just done a water change and trying to be efficient - ie no wet carpet!! I got everything ready for the operation.  I was very pleased I managed to pipe the water out of the window into the garden, saving carrying heavy buckets    a first using this method.  I have a 25 ltr bucket  to refill the tank. which I fill from the hose connected to the outside tap  That was the only thing I forgot to do and run it through first to get rid of  any stagnant water and bugs, oh and I forgot the towel on the floor to protect the carpet 

So after I finished and cleared up, sitting with a well deserved coffee and watching the recipients of my labour, I reflected that it was a bit like a military exercise, not that I've ever been on one 

Even on a good day the carpet usually gets a few splashes of water.   

I bought a python, but unfortunately it wont go on my kitchen tap!  It would have to go on the outside tap, like the refill hose does now), This has to run through the garage, into the house via the dining room and then into the living room. Plus the outside tap doesn't have a drain under it for the waste to run away.  Then it would be cold water only filling the tank.
At the moment, I uses part of the python to empty out of the dinging room window, the garden hose to fill my 25 ltr bucket, which is topped up with buckets hot water from the tap (combi boiler, not tank)  I then use a submersible pump to fill the tank.  So far, this seems to be the easiest change I have done.  But I'm sure I can improve given time - maybe an expensive change of kitchen taps  still involves running piping through the house, or I could just move 

You both need to look up Hoselock tap Connectors. There are designs to connect a garden hose to almost all tap types.  I too have a combi boiler and so I fill my tank with temperature matched water from the comfort of the sofa!
