I have a vaillant ecotec plus 831 and I would like to have a look at the canoe filter -
Firstly,
Do I need to drain the system to have a look at it - Im guessing yes
Is it easy to get to - can I just undo it (left pipe beside pressure sensor)
Thanks in advance
O and whilst Im here - can I just pop out the pressure sensor and stick that back in -or does the system need to be drained for that too
