I have a leak from the ensuite waste . Tested this ages ago all fine . SWMBO has a shower - slight leak . I manage to tighten the trap half a turn - leaks even more !!
Can’t see anything obvious. Trap seems good , rubber seal seems good . Underside of tray hole is a bit tight to that timber - but as you can see in photo’s it’s not catching in . Is there perhaps a different / better trap I can use ???
