Watermaker for Liferaft

Used to have a small Pur Survivor watermaker in the ditch bag. Time for something new but not finding any ???

Company wrote too old to service. Was manufactured 1997. Was packed in original Viking Life Raft last serviced in 2004 until raft was eventually replaced. Current raft has 3 yr service but the water maker requires annual so relocated it to ditch bag but long over due for service.

I contacted several similar and they were all basically for fresh water streams & lakes not ocean water. Maybe the Ft. Lauderdale marine water maker store will come up with one. I ran across a manual for Pur 06 and it said must be treated with a chemical annually or after each use.

I sent them a note so we'll see and if Viking ever gets back to me I would think they might have some info.

They sent me the following:
The product is capable of filtering water with low salt concentration. It is not recommended for desalinating seawater, but it can be used in emergency situations. Filtering large volumes of saline water, such as seawater, can easily clog the RO membrane, reducing its lifespan. Of course, our RO membranes are replaceable, ensuring you have a pleasant shopping experience."
