Plastimo and Nauta bladder material

Just wondering about the material used for these bladders. I searched the site and apparently Plastimo did not return an inquiry as to the safety of the material used. I have also search the web and was not able to find anything definitive about the safety of material use for storage of drinking water for these products. Input welcome... thanks

"Natua flexible water tanks use an exclusive TedlarTM inside lining to maintain a taste-free system. No venting is required for water tanks."

From the Imtra website.
The tank may still kill you, but the water will taste good.

We have two Nauta Water Tanks aboard our boat and have had relatively few problems and no taste issues. The fittings on the tanks are designed such that they can be removed and one can reach one's hand/arm into the tanks to give them a scrub if necessary. We've only had to do that once in the last 10 years when we took aboard some water that turned out to have some debris in it. I was able to remove and clean the tanks and sanitize them, and flush the water lines, relatively easily. (We now carry a clear under-sink canister type water filter with a 10 micron element and threaded hose barbs on each end that allow us to thoroughly filter any water going into our tanks. An additional 2 micron filter/activated charcoal filter between the raw water feed on the output side of the pressure pump ensures that the water is pretty good before it gets to the lines/hot water heater.)

FWIW...

Re: Plastimo and Nauta bladder material

I am looking into them for my Sprite. The 9 gallon tank in my boat was molded into the hull 50 years ago.. what comes out is not pleasant

Art--

We had a similar situation with the water tank on our prior yacht. I finally cut a 6" dia. hole in the top of the tank and used that to scrub out and sanitize the interior of the tank (suctioning out the filthy water with a shop vac) and then dry it out (with the discharge from old ladies hair drier purchased at a salvage store for $5--set on low and allowed to run for several hours). Once the tank was cleaned out, we cut a 2" diameter hole in the bottom for the discharge line from a small bladder tank and slipped the tank into the shell of the old tank through the larger hole in the top by rolling it into a tube. The old tank merely acted as a convenient holder for the bladder tank. A plastic inspection plate was used to cover the larger hole in the top of the old tank. From what I understand, the bladder tank is still working well.

FWIW...

Re: Plastimo and Nauta bladder material

I am using a Platismo bladder and have no probs with it. The question is about how safe is the material used to build these bladders.
