all hoses, short and long, will develop this sort of issue over time....
like others, i run my tap for a bit before filling and i also 'clean' it periodically....ill treat myself to a new one when we get back on the road....
even Gromits 'watering can method' starts with first filling the tank with a hose...

Ours is simple
When at home, tank is always empty with drain cock open and hot tank empty too, both sets of taps open. Therefore there is very little actual water and all is open to air ventilation
Before every trip we run out the garden hose and run it till it passes an air "gurgle" showing that any existing water in the hose is now displaced. Both fresh, then when poss, hot tanks are then filled to capacity (overflowing at the filler point and water from both hot and cold taps. Therefore the fresh tank is full as is the hot tank, both with reasonably clean water.
However, this doesn't matter too much as we never drink water from either tap, all drinking water used on our trips is bottled, the MH tanks are purely for washing.

As an aside, and by preference, we also only take carbonated bottled water (LIDL's usually, but any will do), much nicer to drink, and when boiled miraculously transmogrifies into normal water!!! ( I know the gas boils off!)

So, when en route or stopped at site or Aire, it really doesn't matter what the water quality added to the tank is as it never gets drunk!

I haven't used it yet but I think I will in preference to the Watermaster hose and connector that came with the Nuevo by putting the water directly into the tank through the lockable filler cap.  I reckon it will be quicker and also easier & quicker to wind in the hose.  Obviously the autofill won't function but a bit of water coming out the overflow shouldn't be a problem.  This means that the Watermaster socket will only be used by the Watermaster pump that came with the Nuevo (I'm not joining the watering can club yet!) in which case the solenoid valve will serve no purpose because the contacts on the Watermaster socket are live when the autofill is on and only go off when the float switch indicates the fresh water tank is full.  This being so, my solenoid valve might soon be a thing of the past and be replaced with a 5 inch piece of pipe which will reduce power consumption (0.8A) and will help to improve the flow rate.  All I will lose is the ability to have a permanently connected mains water supply that keeps the freshwater tank topped up.  I won't miss this as I don't use it now.  If I have a tap on the pitch I use it to refill the freshwater tank when I need to which is about once every couple of days.
Although my system was working OK having removed the pressure switch adjustment screw, I have now removed the solenoid valve and replaced it with a section of pipe.  I've refashioned the gauze debris filter to cover the Whale socket inlet when its out of use.  The external Watermaster pump works fine and continues to cutout when the fresh water tank is full.  Filling the tank with a longer food grade cassette hose through the lockable filler cap probably results in more water in the tank because I let it overflow but I haven't noticed any increase in fill speed yet.  The cassette makes recovering the hose quicker.
