Fresh water hose

I use a garden hose myself. I grew up on hose water too.

I use this hose.

The white hose is made from virgin non-leaching materials. Ordinary garden hose may contain recycled materials that could leach unknown compounds, or even a new ordinary garden hose made with leaching compounds. Just stick with the white hose.

For the RV I replace the potable water hoses every 3 yrs.

They ALL seem to get funky.......and I grew up drinking out of rubber yard hoses, swimming/swallowing pond water, playing in the run off from irrigation etc.

We fill fresh water tank and use it for everything.

But even with an in-line charcoal filter the hoses leave I slight taint.

Tires/water hoses.....replace routinely :B

Valterra and make a "taste free" potable water hose. There's a number of potable water hoses available that have an inert plastic that won't impart a bad taste to the water and that also meet NSF & ANSI requirements. I believe the taste free ones all have a blue tracer line along them to identify them. Have also seen them sold as commercial food grade hoses.

Note: The taste free hoses tend to be stiffer and need to be coiled with a larger radius. We have one that has a permanent kink in one spot because I tried to coil it like our old standard hose. Can't get rid of the stupid kink now. Annoying!

I use my water tank exclusively and just re-fill it when I need to. Flush the hose, fill the tank, and done; repeat as needed, no bad taste.

Let the water run for a few seconds to remove the water that's been sitting in the sun in the hose. Filling the tank works because the water is constantly moving.

None of my white hoses has ever caused a taste.

Some people are apparently sensitive to taste due to the material a hose is made from and some aren't.

If you are having an issue with taste, it's not going to be the from the PEX water piping or tank which are made from food grade polyethylene, but could be from the hose used to fill the holding tank.

Not sure exactly what a taste-free hose is made from but still has vinyl in them. Hoses that aren't rated for potable water may have nasty chemicals and metals in them like phthalates, BPA, antimony, lead and flame retardants. Only RV hose I will use is NSF certified for potable water but doesn't need to be "taste-free" for us.

It really is not about the 'taste'.

Garden hoses have lead and chemicals in them. Have for years.

Ya, we all drank out of the garden hose one time or another when we played outside.

BUT we were not drinking out of it all day and night for days at a time as in an RV. If you have kids on board the RV the lead issue is real BIG issue because it affects there brains just like lead paint does.

The so-called white safe hose for RV's has been found to have traces of lead in it also. Much of it coming from the fittings. So it can state 'lead free', but that just means the hose not the fittings. The RV white hose has been shown to have lead in it from the fittings.

Here is but one of hundreds of information sites about lead in garden hoses.

One thing I will pass on from experience is if you are RV'ing in the south. Green 'mold', not algae, but real green 'mold' builds up inside the hose over time. When it lays outside on the ground in the hot southern heat.

One of the best ways to prevent build up of the chems and mold is to NOT store the water hose without completely draining it each time before you store it. And do NOT connect the two ends together.

Once I found that green mold inside mine, I started putting a 1/4 cup of bleach down the hose and then some water before storing and bought a new hose every other month.

RV'ing in Florida does have it's challenges. :(
