I did say I was new to this and finally found the fresh water tank drain behind an access door in the big storage compartment which really wasn't much faster than draining thru the gray/black water tanks
Anyway, I bought this new 2013 Solera last on the 13th and picked it up on the 15th. The new water filter (still in the wrapper) was in the refrigerator when I first saw it but when I picked it up they had already installed it and said they filled the tank to make sure there were no leaks. When I removed the filter last night it had 1/2 dozen or so rust spots on the filter and I hadn't put any water in the RV up until yesterday as I was still learning how to sanitize it.
It doesn't make sense that the dealer would put in the filter without sanitizing the fresh water tanks first and was curious how your first sanitizing went?
Oh yeah, I did find the instructions in the FR manual...
