[Huck]

I use an inline filter when filling my fresh water tank.

I did happen to notice that my water filter that is built into my MS came plummed from the factory so that it only filterd the water that came out of the tank.
I cut the line and put a T in it so that the filter would work on both the tank and city water hookup.

I use a 10 micron filter cartridge for sediment outside my trailer and a 5 micron filter cartridge for taste and odor inside(built in) my trailer.
