Default Looking for suggestions for whole boat water filtration (pic of current setup incl)

I'm looking to install a whole boat system and was considering a 3M A900 system. However, I'm not sure the size of the filter will work well in this setup. I was planning to install the filter after the Well-x-trol holding tank. Thoughts, suggestions, etc?

Thanks,

Jim

pretty sure the 3m aquapure is not a low enough micron filtration to make the water drink-able

i recently struggled with wanting a whole boat system and here is what i decided:
- clean tanks and lines with bleach at least every 6 months
- use a high micron filter when filling up tanks to keep larger particles and crud out of the system
- do not use city shore water connection, instead keep filling tanks and using water in tanks
- add a small amount of bleach to each fill-up
- get a seagull filter with dedicated faucet. i think its .4 micron, use this dedicated faucet for drinking water
- all other faucets should be fine for showering, brushing teeth, boiling water for coffee, pasta, etc
- any system that would really turn your whole boat into drink-able water is $$$$. you can't just add a seagull/seagull-like filter at the beginning of the system because the flow rate will be too slow

again, you need something that is .4 micron or uses UV light or reverse osmosis to ensure the water is potable

Lots of folks routinely drink directly out of their water tanks. Treat the incoming water with a bit of bleach and turn over the water regularly. Don't winterize with antifreeze, blow out the lines with compressed air.

This assumes your source of water is good to begin with...

assuming the lines are cleared, flushed, and sanitized after, i don't understand the concern? of course i'd select a non-toxic anti-freeze that can be used in a potable water system...

The filter should go right after the pump. One of the Watts whole house filters work fine. You can plump one into the hose you use to fill the tanks too if you are double paranoid. What is the issue you are trying to fix?

Of course we are talking about non toxic antifreeze. It still leaves a bad taste. I have 8 outlets/ faucets on my potable water system. I don't think you can ever get all the taste out. Especially evident in the ice from the ice maker when you are making a drink...

gotcha. i guess i dont really taste the sink water... brushing teeth the tooth paste masks it. we plan to drink from a seagull qc2 next season, hoping that will mask the taste... i have a brand new ice maker never connected as it requires AC (we try not to run the generator except there is usually 2 weeks in summer where temps are unbearable and we have to)

If the seagull filter has activated carbon in it, it might remove the anti freeze taste. As for the generator, it's best to use it frequently. Disuse is the prime killer of a marine genset...My generator runs from the time I unplug the shore power until I plug it in again.

let me re-phrase... we use the generator... but ice maker requires AC power 24x7. we use the generator almost 24x7 for 1-2 weeks usually each year. and then use it normally to re-charge, exercise, shorter air conditioning cycles to remove hot air in late afternoon when cabin is boiling, etc... not close enough to keep the ice maker powered... we cruised for 6 months last year and a few months this year... running genset would have equaled over 4,000 hours last year and 2,000 hours this year. we used it 300+ hours last year and 150+ hours this year.

not sure if you looked into them yet but a spot zero system can be installed in the boat, on the pricey side but they do work incredibly well https://www.spotzerowater.com
