I have a dripping bath/shower mixer tap, 2 images attached. I need to replace the cartridge(s), but as it's the only facility in the house, ideally I would like to have the replacement part before I start to dismantle it. I think it was fitted around 2010-2012 and it's a Nabis brand purchased from Plumb Centre. I would appreciate some help in finding the correct Nabis replacement cartridge or a generic one (if it's that simple).
