I'll check the bolts holding the toilet down.
The bowl holds water and the ball and rubber look good.
As fat as the seal between the toilet and the tank that might be my next investigation. I think Scamp uses a wax ring. I have a porcelain bowl so why not a wax ring. I've never had one apart and no real desire to take it apart
but I may have to investigate that as well.
I'll do the standard PMS and see how it goes.
I think I'm going to eliminate both p traps with hepvo valves though before winterizing.
