How to change a fridge filter

Fridge Filter Installation Instructions


This guide will describe how to change a fridge filter on american fridges which use an external in-line water filter cartridge.

Note: This guide is for the newer type of filters which use push fittings built into the cartridge. This may be different to you old existing filter which may have screw stem fittings. If this is the case all you need to do is cut the pipe before and after your existing filter to completely cut it out (follow installation steps below). This new type of filter does not need these fittings since it has push fittings built in.

*important note on push fittings* ensure the pipe is completely smooth and free from burrs around the ends where it will be pushed inside the new cartridge, otherwise slow leaks may occur, if pipe is not smooth cut out the burred bits until a smooth section is present.



Installation Steps

*Firstly please remove the blue sealer fittings from either end of the new cartridge (if present, if not continue to step 1) – check by looking in the hole at either end that the blue sealers have not been pushed into the cartridge during transit, if so please carefully remove them, they can just be pulled out.

1. Turn off the water supply to your fridge.

2. Release pressure from the fridge by drawing some water from its dispenser.

3. Put a bowl underneath your old filter to catch any water, and remove the pipe from your old filter / cut the pipe before and after the cartridge if it has screw fittings.

4. Push the tubing from the feed into the new cartridge in direction with the flow arrow imprinted on the cartridge. Direction is: FEED>CARTRIDGE>FRIDGE. Make sure the pipe is pushed firmly into the cartridge and is

gripped, if done correctly you can usually feel it slide into place.

5. Before connecting the filter to the fridge, hold the new filter over the bowl and open the inlet valve. Let water run through the filter for 5 minutes constant flow to flush out the carbon fines from the new fridge filter.

6. Once flushed, turn off the valve, and connect the other end of the filter cartridge to the fridge, and open the valve again.

7. Check for any immediate leaks, if any are present ensure the pipe is firmly pushed in the push fittings and that the pipe is smooth and free from burrs. Then double check again after several hours to ensure there are no slow leaks.

8. Be sure to check out www.waterfilterman.co.uk for your replacement filters.
