We are currently switching to the Rockwell concentrates. I see that the all of it (including the drums) has an expiration date. Has anyone had a state surveyor question them about drum expirations when you pump it into the storage tanks? I know, it should be used up or refreshed long before the expiration date.

I have not had anyone offical ask.
When i asked Rockwell about expiration dates they told me once the liquid is in the tank it is good for 1 year. The date on the drum is to account for any crystal formation in the barrel. No one can answer this though: June 1 i put acid into my tank, i have 1 year, 2 months later i put more acid in my tank. When does the acid expire? Is it from the 1st batch or the 2nd? If its from the 2nd how can you guarantee that the first batch is completely gone?

More questions without answers from the transition to rockwell......
Do you have Fresenius machines?
If so, which 45 x did you use when you entered the concentrates? there are 3 options in the concentrate list for 45 x on the big F machines, and i still dont have an answer from rockwell.....

Thankfully, we have Braun machines. I had a feeling there wouldn't be a perfect answer to this question. Thank you for the feedback.

I've used Rockwell/Fresenius 45X for years and you should use 45x 81.52g/l bic

When we used drums never had any issues with State surveyors, they just checked the pump log was filled out - did not have exp date, just day pumped, # of drums pumped, tank level in gallons, manufacture catalog number (Ex; C-108 was 2k-2ca) and lot number. that satisfied them, i'd do this all over again - Hate mixing powder!
