How To Replace Filters

Watch the colour of the cartridge. Once it has gone properly brown, change it. Three showers a day works out around one to two months; a single user can get up to six.

1. Turn the water off at the shower.
2. Twist the lower part of the head anticlockwise to open it.
3. Pull the old cartridge out and bin it.
4. Take the cap off the bottom of the new cartridge so the head closes flush.
5. Drop the new cartridge into the same slot.
6. Twist the lower part back on, clockwise, until snug.
7. Run the water and check the joints for drips.
