POSSIBLE CAUSES

REMEDIES

 

 

 

Declining rejection

O-ring seal broken or damaged

Replace the O-ring, check the

(high permeate conductivity)

 

sealing surfaces on the O-ring

(continued)

 

groove, interconnectors, and end

 

 

caps. Replace damaged parts.

 

 

 

 

Change in incoming water

Open the concentrate valve and

 

quality

flush. Test the water for pH,

 

 

hardness, TDS, and iron content.

 

 

A water analysis should be sent

 

 

to GE Osmonics.

 

 

 

 

Inaccurate conductivity

Calibrate the monitor with a

 

monitor or fouled probe

solution of known conductivity

 

 

or check the readings with

 

 

another conductivity meter.

 

 

Replace or clean the probe.

 

 

Check the connections between

 

 

the probe and monitor.
