Measure TDS of each product water sample (para. 2–30c(5). If one or both
samples are still high, leaky O-rings or faulty (cracked) connectors may still be
present, or one or both R.O. elements maybe faulty. Depending upon availability
of time, either repeat steps a through I or replace the elements (para. 3-4).
When all vessels are producing normal TDS product water, reinstall all product
water hoses and threaded plugs.
Resume normal operation.
Step 2. R.O. elements maybe scaled or fouled.
Clean R.O. elements (para. 2-28).
