There is nothing magic about the pickling chemicals. Pink anti-freeze used for winterizing IS pickling. You're done. Leave it be.How can I keep a watermarked functional if the boat is on the Bay 100% of the time? After I winterize it I don't see the point de winterizing it. And then the pickling, how can I that if I'm leaving it winterized?
You can dry out the watermaker but the membranes need to be sealed. If you have a vacuum sealer that uses rolls it's easy to seal them with antifreeze or pickling solution inside. Rotate them at least once a week to keep all portions of the membrane saturated.I wish it would be as easy as pickling. Winterizing throws in a twist and then when you recommission the boat in the spring you need a source of water to get the antifreeze out. I wonder if putting it in dry layup might be the best option.
This is not true when the PG concentration is over 25%. To be safe I would push the concentration to 30%, which will be effectively infection proof. This will require using a mix of -50 and -100 PG.Propylene glycol is well known nutrient for many microorganisms. Exactly why would one want to 'feed' such bacterial etc. contamination inside a 'stored' watermaker?
Exactly, and the reason Spectra, Sea Recovery, and my friend Rich Boren of CruiseRO recommend the use of antifreeze for winterization and pickling when storage space is not an issue.This is not true when the PG concentration is over 25%. To be safe I would push the concentration to 30%, which will be effectively infection proof. This will require using a mix of -50 and -100 PG.
Dow has done many studies on this subject.
Kind of related to why jams and jellies don't spoil.
