[QUOTE="Brute 23, post: 1753185, member: 6291"] So an air brake is not a part we used. We mechanically shut things in and in a lit of cases a vaccum was our friend. Take that in to account with what I type. Sounds like your air brake valve basicall lets air in to the discharge line to alleviate the vaccum through your pump. It's trying to almost keep the pipeline at atmospheric pressure so the pump does the work going up and gravity and the pump take it down the other side. When that air brake opens it will also allow water to flow back from the peak, through the pump, in to the reservoir, to some extent. My solution for that would be a check valve right off the discharge of the pump. That would prevent a back flow to the reservoir and store that water in the line from the peak to the discharge of the pump. If you did that you could put a bypass around it to your suction and basically use it to prime your pump by circulating the water in your discharge. I think that is what Isia Company is describing, also. Please get with some one to help design that. I would hate to steer you wrong and cost you a lot of money or even worse, some one get hurt.
