Temporary hose and tap ...

Yup it would.

I don't think that there is an ideal solution even if I hard plumbed and buried copper pipes I would still have a dead leg with water stationary in it for weeks at a time.

I use a garden hose on a reel....have done for 8 years now. Yes I run it for 30 seconds before drawing off any water that might go in a brew but other than that don't take any specific measures other than lobbing a campden tablet in it.

Our garden hoses are in very regular use so it is rare that water lies around in them for any length of time.
