this would be the case in question, my last thread touched on the spout with the O-ring and i sorted that out and doesn't appear to leak anymore at the base.
i took this pic after reassembling everything, but prior to this, i had faucets/assembly off and spout removed. i tried to pull the case out gently but it seems to be attached to the piping.
obligatory google drive video of the underside cuz photo was blurry as hell: https://drive.google.com/file/d/1cImopHsQcdHDLv_41rZxX9GFBdOcTygA/view?usp=sharing
now the reason for removing it. it appears i've found another leak in the process on the hot water faucet on the left and i'm absolutely sure it's within this case that prevents me easy access to investigate and fix the issue.
when i turn the cold or hot water faucet, it leaks along the left side pipe exclusively, cold water pipe leading to the faucet on the right shows no sign of leakage.
that's pretty much all the info i have at the moment.
thank you in advance for your time and assistance
