If the water is NOT in the shower pan but you can see it below the round strainer, that is NORMAL. For either a Hepvo or P trap system. That is your Water barrier to keep gas/odors from coming back up. Doug
So that is exactly the situation I have. But I guess my concern is that normally when I open all the valves to drain all the tanks, especially in fall when I winterize, I don't ever recall seeing this water down in the drain. Everything is functioning properly the way it should, so for now I won't worry about it.
