Thanks for the reply Joe.
I called DRV about the posts that mentioned the tool supplied with newer units, but both parts and tech support did not know what I was talking about and did not know what tool I should use.
That was puzzling.
I did open the small access door and look into the end of the pump, but still could not clearly see what would fit the opening. I did not want to take a chance on stripping out the pump fitting. We are not having problems, but just wanted to have it on hand in case we do.
I would appreciate hearing what you find out on Friday.
