CS HEPI Fluid System running on just 3 Pumps now

Re WP 5986.  Currently just running three of the four pumps at the Corner Station as I have one off for cleaning.  This pump has been running from the beginning with little break and I was not always so fastidious about cleaning up the drips.  It was an mess and I think there are are a couple bearing leaks at the motor and the pump.  Being cleaned up now though will help evaluate if further action/worry is warranted.  With just three pumps running the drive out to the pumps is about 30% higher than before--may show in a periodic famis task if it is executed during this period.

It's ready to go back together and essentially it is together but some of the fasteners are just impossible to get to without disconnecting plumbing (messy.)  Going to shop for or fabricate a couple custom tools to help reassembly.  WP remains open.
