While we have a dedicated potable water hose connected to a filter that is used to fill the tanks that gets drained after every use and lives out of the sun in a locker on the boat, am I the only one who grew up drinking out of the garden hose? The same hose that hung out in the sun all summer long and was only replaced when it finally cracked and started leaking years and years after the fact? The one that was never drained and lived in the dank basement all winter? And we had well water, not treated city water. Amazing that we all made it out of childhood (and that with riding bikes, skateboards and roller skates without helmets).

Hoses that we depend upon to DRINK from deserve special consideration from hoses we work with.
AFAIK, the concept of having a dedicated 'potable water hose' is so that is does not get 'borrowed' and used for other less clean jobs: Like flushing the poop tank, the antifreeze or other contaminable vessels.

The hose is made of rubber. Put a nozzle on it, Turn the faucet on. Then spray a lot. The difference in pressure widens the hose and let's it shrink loosening crud up on the inside wall. Then flush that all out.

Regarding cleaning them, add a half bottle of bleach, and connect the ends of the hose. With the hose coiled up, rotate the hose a bunch of times. Then disconnect and flush out.

FWIW, Camco makes a blue hose advertised as suitable for potable water.

From what I have seen, many hoses are certified for potable use. The issue is that they should ONLY be used for potable. Mixing uses is where the trouble comes from.

People forget that the hose used to fill the boat should NOT be the one that is stuck in the black water tank to rinse out the tank. Bacteria loves to hang around.

Also called cross contamination or cross connection in professional circles. It is the lone reason I will never consume water from any of your boats, no offense. I will never book passage on a cruise ship for similar reasons.

I use a standard garden hose which never gets drained or cleaned. I don't filter my water or add anything but water to my 34 year old tanks.
The water tastes great and I never get sick.

Maybe I'm just lucky.

I don't think so. As nanny-state mentality expands around the world I think there are people who are paid to sit up all night thinking up things that could go wrong, no matter how far fetched or without evidence or proof they may be, and then start wringing their hands and wailing until the media and feel-good politicians take notice and then it becomes a Thing To Be Protected From.

While I applaud them for this, I'm amazed that the London Underground still gets away with simply telling passengers to "mind the gap" when entering or leaving the cars and then leaves it to the passengers to take responsibility for themselves to not fall through a break a leg.

As Capt. Bill said, the algae growing in a water hose is probably edible and in fact is probably good for you.

I expect there's not much difference between the dock water supply being fed into a "potable water hose" for drinking water use on board... and that same dock water supply being fed into that same "potable water hose" and being used to wash the boat. IOW, just because the hose is carrying potable, there's some flexibility in the end use of that potable water.

But sure, using that hose in the black water tank wouldn't be a great idea. I don't happen to personally know anyone who would "forget" that.

We have a water supply at the slip (white hose) and then another water supply hose at the marina's fuel/pump-out dock. I drank out of garden hoses when I was a kid too and slept on the shelf above the back seat of my mother's 1973 Caprice on long trips and lived to tell about it so I'm not too fussy, but I've seen way too many boaters stick the marina's water supply hose down their waste inlets (outlets?) for me to ever use a gas dock water hose to fill my water tanks. Stomach acid is pretty good at killing lots of critters but I don't want to test it that hard.

Stick around a marina dock for a couple hours and observe. You'd be amazed at what you will see.

Guess we live in a special marina; don't see too much stupidity... aside from the few folks who sometimes have trouble docking...

Funny thing. I had to go rescue my hose from a neighbour boat. I guess he needed it more than I did. Never had that happen before...
