This my first post.
We just purchased a new to us 2006 Sunseeker 2860ds.
My question is does this water filter, filter the water while you are using "city water" or only filling your holding tank?
The only reference I have to the water filter was when the RV dealer did a walk through and said he said "you don't have to worry about the water filter for a year, we just put in a new one".
Any help would be wonderful.
Many thanks.
