Pur Survivor 35 - Used or New

I have found a number of so-called "new" Pur Survivor 35 water desalinators on Ebay. They are offerred for half the price of an online store. Even though they are advertised as new it seems that most were manufactured some time ago. Are there any problems with a new machine machine that has been sitting for a couple of years or more?

I wouldn't have thought so. The primary issue of operational ability in these machines is the membrane and that (I think) will only get damaged by having polluted (oily) water being pushed thru it.

There are probably more educated opinions here but I don't tink that membranes degrade based on time alone.

It may simply be that technology has improved and there are similar machines available today that do a better job, reducing the value of the older technology substantially.

Do these machines come with an form of warranty?

Yes, the membrane can also be destroyed if it wasn't pickled. You need to pickle the membrane, usually in an acid or base solution, to help prevent bacterial/fungal contamination of the membrane.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Be wary of fraudsters.

Make sure it is what they say.

The membrane is the core of the system. It must be kept wet I am told. If it dries out in storage, it is toast, I am told. The seller has money back guarantee and a good record. A new membrane will cost around $400. Plus the aggravation of finding one. The seller is saying up front you WILL need a new membrane.

Most likely army surplus. SOme guy prob bought a truckload of them for nothing and is making a killing at $190 each.

Will contact a buyer and report back here in a few days. ANd probably kick myself cause I didn't buy half a dozen of them.

Saw the unit last night. All appears complete and as advertised. Unit has peculiar smell, probably the fluid in the membrane.

There was small amount of fluid in one of the hoses. Not sure why.

I see many more units on Ebay now, at generally double the original price.

Katadyne will probably be flooded with requests for membranes now.
