PROBLEM
POSSIBLE CAUSE
CORRECTIVE ACTION
Low product flow rate
Low pressure feeding
membrane
Low pump PSI
Reject GPM flow rate too
high
Excessive PRODUCT line
backpressure
Low temperature incoming
tap water
Membrane needs replaced
Verify that the incoming tap
water supply is fully open.
The pressure on the inlet
gauge should be > 20 PSI
when the MRO is operating.
Pump should be operating at
175 – 250 PSI.
Adjust Reject Water flow
rate.
Check for restrictions in the
PRODUCT WATER FOR
DIALYSIS hose. Check the
feed pressure gauge on the
dialysis machine. If the
dialysis machine does not
have a pressure gauge,
install one inline.
Consult the Temperature
Correction Chart to
determine if the flow rate is
normal in relation to the feed
water temperature.
Replace the membrane.
High Bacteria Count
Too long since the last
disinfection or the procedure
was not performed correctly
Disinfect the MRO following
the procedures in Section 5.
