is much nicer).
Is it reasonable to completely leave out the charcoal filter in the flushing system.(If I need to use town water for flushing I understand I will need to use a new charcoal filter).
Would a 5micron filter be sensible in place of charcoal filter to provide double protection against debris from the tank?
The 5 micron pre-filter will work. Of course you will be changing it out more frequently than you would the charcoal filter because of growth on the filter. But Jon, who has become a Spectra expert in his own right, is correct. There could be warranty issues depending if the membrane is still under warranty. The charcoal filter itself only protects the membrane but it does filter down to the 3 micron level as well. You are also correct in assuming debris in your fresh water tank/s. Most people would be shocked to see what really lives in their tanks
even with careful attention to keeping them clean. Personally, I recommend good dock
water every now and then. The residual chlorine that is in good dock
water helps keep your tanks under control. Only filling with RO water and especially rain water is a recipe for all kinds of growth in the tanks themselves.
If you are filling your tanks with RO water, rain water, dock water or any combination of the three, I always recommend a good filter (charcoal and sediment) between the tanks and any water receptacle on your boat you plan to drink from.
