Many homes are now installing water filters to ensure they have safe drinking and cooking water. An under-sink water filter is a popular option. The under sink water filter takes up little space but it is easily hidden from view. It will need to be maintained as with all filters. Replacing the filter is easy.

Get Your Supplies

There are not many tools required. To make the process of removing canister housings simple, a filter wrench is recommended. If a filter wrench cannot be used, the housings can be easily removed manually or using another tool. It is recommended that you use towels or another absorbent material to clean up any water that has dripped. It is possible that new O-rings will be required, so it is a good idea to keep those in stock. A pressure gauge and an air pump are also necessary. You can use a bicycle pump. You will also need an under-sink water filter

Turn Off The Water Supply

Turn off all water-flowing valves before you begin to remove any parts. The valve that provides water to the cabinet is the first thing you should do. Turn off the tank valve if you have one. Turn off all valves that are connected to your systems, such as those on the pipes or lines.

Next, reduce the water pressure by letting out as much water as possible. Turn on the faucet connected to the water system to let the water flow. After the water stops flowing, turn the faucet off.

Modify The Sediment Filter

If there are multiple cartridges in your system the sediment filter is the first. To loosen the housing, turn the cartridge housing to your left. You will need to carefully remove the housing as there may still be water in it. Take out the sediment filter and drain the water. If there are any sediments at the bottom, rinse the housing. If it is still dirty, wash it. The O-ring at the top of your housing should be inspected. If it is damaged, replace it. Clean it according to the manufacturer’s instructions if it appears dirty. The new sediment filter should be placed inside the housing. Attach the housing to the bracket. The housing should be tightened until it is secure, but not too tight that the O rings are compressed.

The Carbon Filter Can Be Changed

Nearly all filters contain carbon filters. A carbon filter will be found on one filter in your system. If there are more filters, they will likely be carbon filters. It is nearly the same process as for the sediment filter to change the carbon filter. You will need to follow the same steps until you reach the carbon filter removal. You will now need to inspect your filter cartridge.

O-rings should be placed at the ends of each cartridge. They should be removed from the housing. If they are still in the housing, the O-rings will cause the housing to not fit properly. This could cause your system to leak and not filter properly. Pay attention to the orientation of your carbon filter. Each filter system will have a different up-and-down end. Remove any O-rings in the housing. As before, inspect the O-ring at the top of your housing and pour out any water. Place the carbon filter in the housing with the right orientation. Adjust the fittings until they are snug.

Set The Tank Pressure

Check the pressure in your tank to make sure it is properly adjusted. The valve cover should be removed from the tank. To avoid false readings, make sure that the tank is empty prior to taking a reading. A pressure gauge is used to take a reading. You can adjust the pressure to the required psi either by adding or removing air from the pump. Make sure to take a final reading before you replace the valve cover.

Turn The Water Back On

To allow the water to flow again, open the valves. The main water valve is located at the back. Next, open the main water valve at the back of the cabinet. You should check for leaks. When changing a filter, hoses can be pulled or bumped. Leakages should be repaired immediately. Let the tank pressurize. To get rid of air and flush out particles, run the water for a while. You can then check for leaks once more.

Extra Maintenance

O-rings need to be changed at least once per year. They can crack or become brittle. They may also become too compressed and not provide a good seal. If they are dirty, you should wash them with hot soapy water. You can also clean the housings with diluted bleach. Before putting the housing back on the system, make sure that the bleach has been completely rinsed away.
