 I don't have one to begin with, thus part of my problem 
But from what I've been told by Aquasafe, the ASOV won't work without back pressure. A pressure tank will still provide that pressure even though you use a gallon or two, while just a float valve on Brute can will only provide back pressure until the first time your ATO fires up and drains the teeniest bit of water out.
