Yeah, the reason you need the rinsing is 'cuz when we put that stuff in just 
after draining it, there tends to be water left in the system, which when the 
Evans gets closer to full tilt (it goes up to 250), that water turns to steam, 
which then expands and forces out the Evans between it and freedom...  It can 
be kind of messy...  Another way around this is to 'gently' use an air nozzle 
and blow it out, not too much pressure, as well as a shop vac to coax out the 
hangers-on...
