The water quality is rather poor on campus, as such the Water cooler in the STEW G68 kitchenette has 3 internal filters, and a pre-prefilter located under the sink.
The pre-prefilter needs to be replaced every 6 months, so extras should be kept on hand (keep Dan in the loop on the inventory)
Replacing the "pre-prefilter"
The new filters have some loose carbon particulate in them when they are new, this MUST be flushed prior to operation or else the particulate will clog the sediment filter.
