Issue
Possible Cause
Corrective Action
Low product flow
rate
Low driving pressure.
Increase feed pressure. Consider pump for low pressure locations.
Use short tubing runs to decrease flow restriction. Increase tubing
diameter for longer distances.
Low water temperature or high total dissolved solids (TDS).
Increase feed water temperature or feed pressure to compensate.
Plugged prefilter.
Replace plugged prefilter. Consider sediment prefilter for non-
chlorinated applications.
Scaled or fouled RO membrane.
Replace membranes.

Poor product water
quality
Water sample taken during system flush.

diameter for longer distances.
Plugged pre-filter.
Replace plugged prefilter. Consider sediment prefilter for non-
chlorinated applications.
