Hi. My Grohe bathroom wall mixer taps drip occasionally. I was going to remove the cartridges and give them a clean with vinegar as a first go to see if that will fix it. If that fails, I will replace the cartridges which a pain because they seem to be an order-in item. I have two questions - is what I said the right way to go about it and can I do this cartridge clean or replacement myself under the new plumbing regulations in Victoria? Thanks
