Hi All,

Tonight I have put a new RO membrane in my 100gpd RO Man RO unit.

However after flushing well and leaving to run to drain the TDS out won't go below 19!  With a new membrane I usually get 2.

Anyone had a simular problem and know what to do?

Thanks

David,
when I upgraded from a 100 to 200 gpd my second membrane was giving a higher reading than the first, I contacted ROman who suggested I remove the membrane and reseat it just in case it wasn't quite "in". This then lowered the reading from the second membrane, maybe try this to see if it helps

John,

Thaks for your reply.  I tried that - still the same - contacted Cleantech today and Mike thinks there may be a hairline crack in the caseing   Going to get another caseing and see if that works - if not - must be the membrane
