So I run my municipal tap water through a carbon filter
, actually 2 of the same filters in-line...just so I can filter at a little higher flow rate. I have heard not to filter hot tap water through these, so I have been just using the cold water tap.
My question is this: in an effort to save time and energy heating up mash water, can I run 80F or 90F water through these filters? What is the upper limit to the temperature my water should be flowing through these filters? Also, is there any advantage/disadvantage to water flowing through at 40F compared to 90F?
I like to shave time off the brew day where I can, but not at the risk of reduced quality.
