Re: auto seal system
I have a 3 hose syrian chiller with the autoseal, and it does work well for having all the hoses going, but I rarely ever do. I have the bearings all taken out, 2 hose plugs inserted, and I even drilled out a hose adapter, to get rid of the "screen" in it, so its just a big hole.
Now, unless you do what I did, and drill out an adapter, then you won't notice too much of a difference with the BB in or not. Sure every little bit helps, but boreing out the adapter makes a HUGE difference.. I have a normal one still to swap out when I want to convert back to multiple hoses.
