    6 Maintenance Change the fine filter Replace the cartridge of the mechanical fine filter (pre-filter) once a year. If there is a high pressure loss, filling the pressure tank takes more time. This can be caused by a high turbidity content in the cold water. In this case, replace the cartridge of the fine filter as required: Close the cold water inflow and the pressure tank shut-off valve.
