Excellent. This is exactly what I was hoping for. Thanks for the help.
@bturner2 - - - the dealer did quite a bit more with the winterization last Fall. I have very solid confidence in my local MC dealer, which is a relief. I just wanted to do things myself if possible. These replies make it a lot easier.
Will also check if the impeller was changed out last Fall. If not, I'll add that to the list.
