Thanks for your suggestion. For reference I have uploaded photos of the limescale build up after one shower.If its blocking in the shower head bar, then remove that troublesome microfilter and replace with an open rubber washer to seal with the hose. That way any micro debris will pass straight through the shower rose. It won't eliminate the fine scale debris, but it will allow a shower to be taken
How do you recommend removing the micro filter? Having looked at the one that I have it looks like it's part of the shower head and it can't be removed.
