Hi fellows. I changed the default tap outlet that came with my toilet handspray tap to another type of adaptor so that I can connect, i.e. screw in, a handspray to use. What's perplexing to me is that the areas (seams) where the new adaptor joins the tap outlet, & where the handspray joins the adaptor, leaks/squirts water when the handspray is connected. The following video demos everything: https://youtu.be/sDANZystt4s This happens despite/regardless: everything is tightened as much as possible I applied thread-seal ("white") tape at all areas my handspray is actually "released", i.e. water allow to flow out ("in use") whether I fully turn on the tap outlet or turn it on very so slightly only, i.e. a lot of water being received on the mains side, or very little water being pumped in all the black O-ring/water-saving thimble all installedI just don't understand why there is still squirting. The more amazing thing is, once I reverted to the original outlet adaptor, i.e. the kind that have to be used to a rubber hose & has no external screw thread for connecting handsprays, even without thread-seal tape & full-blast main tap, also no leak! What gives? The adaptor that I changed to is on the left; the original one that came with my tap, is on the right: Can assist? Or did I buy the wrong type of adaptor? But the size correct leh...
