So bottled water seems to have done the trick and gave the filter a gentle rub. Now building up the oil with a couple of batches but hopefully that solves the mystery. Still not a big fan of the idea of buying bottled water though
Glad it worked. The water where I am is really hard so the taste with bottled water is very noticablely better. Hopefully I'll be able to stop once I get my mitts on a Peak water filter!
