Hi all,
I'm designing a raw water pump station and am unsure on how to proceed with air release valves on the pump suction header.
My original plan was just to put the same, air release/vacuum breaking type air release valve used throughout the system. I have since realised that the suction pipe will potentially have lower than atmospheric pressure, but I do not want the valve opening under a vacuum and bringing air into the system.
My question is, would a simple ball valve to drain be sufficient for a pump suction header? As far as I can tell it will only need to vent on commisioning, or are non-vacuum breaking air release valves common for these applicaions? The valve supplier I had been in contact with does not have a non-vacuum breaking type which has made me second guess it.
Any advice here would be great, I'm new to the piping scene.
Cheers.
