  • Remove your aerator and attach the diverter valve in its place (use included brass adapter if required). Push the hoses into the filter. Turn on the diverter valve, flush the filter for 10 minutes and enjoy! For the first 72 hours, the faucet diverter valve will drip intermittently, until the filters become fully saturated. Once they are saturated you should anticipate a residual flow of water each time you use the filter, as the system is vented and designed to clear the line.
