There could be a misunderstanding here. Speedseal produces 2 kits: standard Speedseal and the Speedseal Life. I agree with your assessment of the original Speedseal but the Life unit is different.
Speedseal machined a recess into the cover and add a Teflon disk at each end of the impeller. The end cap on the water pump is then sealed with a thin rubber gasket. This is the type I have on the Volvo; I can report in excess of 1000 hours of use without failure using a 500 hour replacement regime. The impellers show surprising little wear upon removal. In my opinion, this is a much improved product.
When I talked to Speedseal about 2 months ago, I asked them to duplicate the latter design for the Onan.
That said, I also procured a second water pump… as per your suggestion.. and yes, I have a wet/dry vac on board. (… a frequently used tool..) Your suggested procedure is too good to ignore. :-)
