Bill,
Well that got me out to trace the pipes. I was wrong about the water going through the filter before entering the tank - it does not. Doesn't matter if you fill from the top like you do, or through the city water inlet as I do. Both ways still have a risk of over pressurizing ( not the plumbing ) but the tank itself. I minimize that risk by the timer and having three ways for the water to overflow if I forget - 1. the built in overflow, 2. the top fill on the passenger side which is open, 3. the top fill on the driver's side which is open. If you fill through the top you could still forget couldn't you and in that case at best you would have only two places to exhaust the extra water.
The coach is obviously setup for folks to use the city water inlet as their source for water and go directly into the piping system. There is even a regulator on mine that limits the pressure to 45 psi, so says the label. I choose not to do that as I like the pressure from my Headhunter which is higher than the 45 that the regulator allows, and I never have to watch the level in the gray/black tank. It cannot get too high since I will run out of water from the potable tank before it fills up.
Knock on wood, the plumbing and such has been problem free. I find it takes around 15 minutes to fill my potable tank - depending upon available water pressure at my site. So bottom line, I think filling from the top or the city tap is very much personal preference. If there is any advantage to my way it is I don't have to do a thing except open the valve at the post and walk away while it fills.
