Now that our member has returned with both the caulk gun and reverse osmosis filter, we've done work to observe the filter. The first thing we noticed was that it didn't work as we initially thought it did, since it had a tube in the center that led directly out the other side. At first we thought it may have been a mistake, but upon further research we have determined that the pipe through the middle is the output, while the membrane was surrounding the tube itself. Therefore, water must be pumped into the outside layer of the filter, and the clean water will be produced through the pipe in the center.
