How to change a water filter.

I live in France where the water is thick with calcaire. Water filters need changing fairly frequently. This short video explains how you do it. Those with hearing problems...
1. Turn off water ( drain nearby kitchen sink taps until water no longer flows from the tap).
2. Place a bowl under the filters to catch water.
3 Turn the large plastic filters left. Ours were really tight and there is a tool you can use but I eventually managed to undo Ours.
4. Take out old filters and discard.
5. Put the new replacement filters into cartridges and screw the containers back into the black housing.
6. Re tighten....do a good job or they will leak.
7. Turn the stop back on and hopefully jobs a good un'.
