This was not the manufacturer's engineering, this is a jerry-rigged afterthought from a manufacturer who SHOULD by all rights be replacing the entire unit with the current model. Since they have not done that, I have done everything physically possible with the parts they sent me, so enough already. As I said, I'm done dealing with this. As far as whether I'm "irresponsible" or not, it's my house and it's my business, not anybody else's and everyone needs to respect that. Jesus Christ, I have much better things to do.
So go bother "Teddy" who REMOVED his regulator after finding out it took over three minutes to be able to reflush. Sheesh.
