(Hugh, Eric)
We started recirculating HEPI fluid to BSC6 piping after having it recirculate locally at the pump station for a couple weeks.  No observed leaks.  Had been set at 57.5Hz(1725rpm) with a pressure of ~45psi and reduced the speed to 35Hz at ~30psi.  Will leave it at 35Hz over the weekend and then go back to ~57Hz Monday.
