With the suction control closed, and everything downstream tight,
whether or not the checks were fully seated would not matter, right?

Subject: RE: Pump Discharge Piping
Does this pump supply any underground pipe, or 100% above-ground pipe?

Subject: Pump Discharge Piping
I have a fire pump installation that is having issues. The
contractor has successfully completed a pump startup and test.
During a separate follow up visit, the pump technician began having
trouble getting the system back up to maintenance pressure after
fire pump operation. The discharge piping has an elbow between the
pump and the discharge check valve. It was first suggested that
this check valve was defective, so it was replaced. The same
problem was experienced after this replacement. It has been
suggested that the elbow directly after the pump is causing
turbulence that is preventing the check valve from closing properly.
I can find nothing in NFPA 20 or the handbook to suggest this is a
concern. Have any of you seen this? What would your recommendation
be?
