Another vote for Flexzilla hose here. They are food-grade and very easy to coil, much more so than the standard white hose.

you nailed it Ray, it makes no sense to put a 5/8 or 3/4 hose onto a hose bib with a 3/8 hole in it. the hose bib may be threaded onto a 3/4 water line but the valve in the bib will only be about 3/8, unless you have a full port valve or a gate valve .

Zero G is NOT BPA free if that is an issue for you. Also, they say not to use under constant pressure FWIW.

I've been using a white coiled 50' hose for years.
Never any problem, plenty of flow, so easy to store
and use. Got mine at West Marine.

Thank you, bucks2.

Both not true. Prove it to yourself. Put a 5 gallon bucket under a spigot (any of your 3/8" spigots will do) without any hose, etc. Time how long it takes to fill. Then put your 3/8" hose on the same spigot and fill the same bucket and time it. Then put a 3/4" hose on the same spigot and time it. You'll see first hand how wrong your assumptions are.

Or read any of thousands of articles online explaining this exact thing. Here's only one that explains it pretty well. That short distance smaller opening does affect the flow, but not nearly as dramatically as the hose friction loss does.

in the link above they don't consider the dia. of the valve that's feeding the hoses. sure a 3/4 hose will flow more than a 1/2 hose but not when its being fed from a 3/8 valve. only so much can pass through that 3/8 opening.

That's true, only so much can pass thru there. BUT, that's not the limiting factor for our uses. The friction loss in the small diameter hose is. You really need to do some reading on friction loss in hoses and fluid dynamics. I'm done here. Those who will not learn, cannot be helped.

I use a 25' 5/8" white hose. I have never needed a longer hose and more often than not I have to curl a few feet of hose up and slide it under my coach out of harm's way.
I don't make a science project out of rolling up the hose or storing it. I drain the hose, roll it up by hand and screw the ends together to keep drips out of my storage compartment, wipe the hose off and toss the hose into my compartment.
I carry a second hose "just in case" but haven't needed it in the seven years I have used my white hose.

What about the 2 gpm flow restrictors on the RVs faucets? They don't care about the outside hose.

You have a 2 gpm flow restrictor on your tank fill? You have the patience of Job! Does your clothes washer also have the same restrictor? How well does that work? You see there are times and reasons to flow more water. Since many (most?) of us are not boondocking during the majority of our time, saving the last drop of water is not on the top of our list. As always though, it's your RV do as you wish.

We must be on different threads. I didn't say a thing about the FWT. I think I said faucets.

The OP asked about hoses for water supply.

TCollins · 11-07-2019, 06:18 PM

Thanks to everyone for your suggestions. I will probably go with a 1/2" Flexzilla or Zero G. I only have the kitchen and bath that use water so the 1/2" will be adequate.

I have never gotten along with the white hoses. They are too stiff and it seems like one of the loops always wants to go off in its own direction when I coil them up.

I do carry a section of garden hose for non potable uses as well.

I actually have a coiled hose and it works fine! My wash machine works fine with the hose as well.
I'm not concerned with maximum volume. I simply want adequate volume.
My 3/8 coiled hose work fine.
The real plus of the coiled hose is you don't need to roll it up! Ever.
I just pick it up and toss it into the storage bay, no fuss no muss,
no: rolling, bins, baskets, tubs or wraps required.
Raise it up so all the water drains out and toss it in.
If your anal enough you can screw the ends together to keep critters out.
I seldom screw ends together, but I do let the water flow through the hose for a few seconds to rinse it out before connecting to RV.
Despite all the naysayers a coiled hose is a very viable, easy and simple way to supply water to your RV
