Young engineer working on pump project. Pump suction/discharge is cleared with air at end of operation. I am looking at installing new pump down a level. I have option of moving automated block valve on suction to lower level or leaving where it is on upper level. It is a PD pump and running dry isn't an issue. I'm not sure how to figure out if it is advisable to move the automated block valve. Seems like it would help get the liquid to pump faster with more head pressure if I do move it but I'm not sure if it will be an issue if I don't move it. Also struggling to figure out how to determine if the air is enough to clear the additional pipe.
