Herman and all,
I discovered that my water filter housing wrench will fit the sewer fittings perfectly. Plan on getting another one or two and using them. Also, thanks, Paul, for the Magic Lube suggestion. Between the two of these, I'm sure I'll never have this problem again.
Glad to see others saw this and found help as well. Getting old is "****", but appreciative of the time here.
Thanks to all.
