Reduced Contaminants


  1. Unscrew and remove your existing strainer/aerator from the end of your kitchen faucet (standard thread loosens to the left or counter clockwise).
  2. Screw diverter valve onto faucet, remove/add adapters as necessary. Visit your local plumbing store if the included fittings are not a fit on your faucet.
  3. After you complete the above steps, turn water ON and PULL the PIN on diverter valve to divert the water to the filter.
  4. The first use of your new filter may take a minute or two while the canister fills up with water before it passes through the cartridge and out the spigot.
  5. Allow water to run though the unit and out the filter spout for 2 to 3 minutes (first time only). This process allows for “loose carbon fines” to be washed out.
  6. If leaking occurs from any point of the housing unit, it will need to be hand tightened at the point of leakage.
  7. The pin on the diverter valve is spring-loaded and will automatically return on its own when the water flow is terminated. (DO NOT PUSH PIN IN): This would weaken the spring and cause the pin to lose its mobility. When you turn your water back on, it will come through your faucet as normal again.
