As soon as i got home i grabbed that xtra valve and did the breath test and dang i about hurt myself. Took the spring out and what a difference. I took one of the springs out of one valve in the boat and left one in-they sit side by side. Sunday i will try to get to the lake and see what kind of differnce there is and snap a photo of the amount of water coming out of those two valve's. My bigger valve also has this spring and i could not blow any air thru it-took the spring out and again what a difference. I also have some bigger size hoses and will see if that does anything. Your bucket test is VERY encouraging. Now i just hope it does not rain on sunday.
