Re reading the First Need "test" bottle... "Food Dye for canister
integrity test (use two drops per glass, see full istructions)." When added
to clear water causes blue coloring, which when pumped thru the First Need
should appear clear... I have not tried this on any other filter than my old
(now unused) First Need...
I've got a call in to the PUR folks (in MSP/SP), attempting to see if this
(or food coloring) is a valid test...
I'll try to contact the Sweet Water folks also...
More later when I get any responses...
