FLEXIBLE FRESH WATER HOSE

They make expanding hoses that are safe for drinking water:

Can't get any better than this one. Can't kink, ultra light, more flexible than you can imagine....stores in a compact wad if you dont wind it up in a loop....and I swear it is self draining. Don't be cheap and turn away from this one. ... just look at its ratings....

Apex Zero G hose

I've been very happy with our Flexzilla hoses. They stay almost as flexible at 10 deg.F as they are at 80 deg.F and are easily coiled up for stowing. They also don't kink under pressure.

Zero g hose. Try it , you will not go back.

+1 for Zero-G

You won't go wrong with either the Zero G or Flexzilla. I have both (Home and RV) and am happy with both.

If the zero g is coiled and connected... will it stay coiled as I turn on the water pressure? or does it flip out?

I'm so bummed that my favorite drinking water safe hose is no longer available. It rolls up flat on an included reel like a fire hose. I bought the last two an online RV shop in Utah had and when the second one dies I guess I'll have to try a Zero G.

I wonder how long the Zero G hose will last in full time use?

I recommend AGAINST the expanding hoses as if the park should lose pressure they can pull the connector right off your Rig (major mess. easy repair but major mess)

Ever see those steel wrapped hoses... Dollar Generous.. er. general sells them .

I have one. Easy to wrangle. AND it seems not to mind being run over.

It was suggested to me by a fellow RVer and I used one for about 3 years before the Rig got totaled (Nothing to do with the hose) still have the hose.
