A: You will need the canister wrench to replace the filter and a container to catch excess water. Open the faucet and let the water run. Turn off the water using the cut off valves under the sink. If you dont have cut off valves or they dont work properly then you will have to turn off the water at the water meter. You have to release the pressure inside the canister by pressing the pressure release button on top. Once the pressure is released you can then proceed to unscrew the canister using the wrench. After unscrewing the canister by hand, remove the old filter and replace it with the new filter. Install upright. Re-assemble the canister with your hand and tighten with the wrench. Turn the water back on and check for leaks. Answer provided by:  TERRELL (4/24/2013)
