Make final tubing connections: Push tubing onto the outlet port of the filter head and the inlet port of the faucet adapter. If necessary, secure with a hose clamp.

 Install filter cartridges: Once you have installed the filter housing, now install the filter cartridges. You must install one or two cartridges depending on your specific filtration system. Generally, when using a dual-cartridge filter system, the first cartridge should be a sediment filter, while the second should be a carbon block filter.

Start-up system: Once the filter is installed, it is essential to start it. First, ensure all connections are secure and there is no water pressure in the line before beginning. Turn on a faucet downstream of the filter to let air enter the line. Next, turn off this faucet and open any valves above or below the filter.

When a reduction in flow rate occurs: Another indication that the filter is ready to be replaced is when you notice a decrease in flow rate. This could mean that the filter has become clogged and needs to be changed quickly to maintain good water quality.

How To Replace Pre-Filter And Post-Filter Cartridges?

 Lift the faucet handle: Turning it to the on position diverts water through the filter.

Turn off the cold water
Turn off the water

Turn off the cold water: Before beginning the installation process, turn off the cold water line connected to your sink. This will prevent any leaks or other problems from occurring during installation.

Twist the filter cartridge counterclockwise: The filter cartridge will come loose and can be removed. Make sure to dispose of the used filter cartridge according to local regulations.

Pull cartridge from the head: Once the head has been removed, you can pull out the water filter cartridge and discard it. To do this, grasp the cartridge’s handle with your hand and twist gently to unlock it before pulling it straight out. Clean any debris from inside the housing.

Wet the O-Rings seal

Twist counterclockwise to lock into place: The filter should fit snugly but not too tight. Next, locate the water supply valve under the sink and turn it clockwise to the “On” position. After allowing the water supply line to fill up, test the connection by turning on the cold water tap.

Open the cold water feed valve and check the leaks: Ensure that the cold water feed valve is open. This can be done by turning the handle counterclockwise until it stops, then back one-quarter of a turn to open the valve. After this, you should check for any leaks in your plumbing system at the points where the filter was attached. If leaks occur, you should use pliers or a wrench to tighten the connections and stop any water loss. If necessary, add extra sealant to ensure the connection is secure.

Installation Troubleshooting

Tank Leaks or Damages
Water leaks from openings

Water leaks from openings: If you notice water leaking from any openings, check that the washers are firmly in place and the filter is adequately secured with the locking nut.

If these steps do not stop the leak, it may indicate a faulty connection. Disconnect the filter and apply pipe thread sealant to all threads before reconnecting and securing with locking nuts.

Water pressure is low
