Leaks on Barnstead / Thermo D4641 E-Pure System

Date : 8/20/2015
From : John

Question

Troubleshooting I have a D4641 unit It has a leak at one of the filter canisters at the top locking nut I tried replacing the Oring still no good It was a new Oring but not sure how old it was seemed to be fine Do you have any secrets or tricks i could try Any advice would be helpful Thanks

Answer

Make sure you are on the last click on the housing, that you don’t have nicks in the flat surface of the head or bowl. It may be leaking between the head and not at the head/bowl. You can switch the bowl and o-ring for one of the others and see if the leak moves.
