Our domestic water supply couplings are leaking. In the attached photo they are slowly dripping right at the T junction. Nothing big, maybe a drop every 10 seconds from both the red and the blue lines.
We've tried to replace the o-rings and some seem to perform better than others, but the leak still seems to persist. Has anyone experienced something similar and successfully solved it?
Lots of teflon tape? Some form of pipe glue?
