I bought 2 of them and wasn't totally happy with them so I took the best features of both of them and built one exactly the way I wanted it set up. I have performed over 1000 flow test since I built it.
Since you built your bench what pump did you use, how big is it and what will it flow max... I wouldnt mind building one.. I had a little thing that I built years ago... it just wouldnt do much
