Dear Experts
I purchased Caroma COOLIBAH CLASSIC CROSS WALL TOP ASSEMBLY TAPS on 4.9.22 from Bunnings and installed on the same day so far there was no issue with dripping water.
It is 1/4 Turn Ceramic Disc Spindle
Couldn't find the page for the taps on Bunnings website may be it is discontinued item , below is same item but on ebay

On 2.1.25 means before 8 days started dripping on cold water tap not hot water,,,,,please see the link for video
