Trouble Shooting
Problem What To DoPossible Causes
Flow reduction
of pure water
outflow
High TDS in
RO water
Water Leakage
Blocked filter element
The filter element exceeds life
requirements
The main water supply inlet

fresh water storage tank valves
are not fully open
The water in the pressure
tank is run out
Need to flush or replace the filter

rejection rate when working properly.
Meaning if your Municipal tap water is
500ppm, then the purified water is
less than 50 ppm.
Poor assembly of O-Ring
seal between filter
housing and the cap
Need to reassemble O-Ring between
the housing and housing cap and lock
it with the filter housing wrench
Poor tubing connections
