Plumber fixed an issue but created another

Just watched this. At the very end, is that the final water level in the trap or does it go down further? With the internals of the trap removed I'd expect there to be hardly any water in there.

If that is the 'natural level then it's very high and suggests either a blockage in the pipe or that the pipework goes uphill from the trap.

Good call, NSG.

If the water level inside the trap remains anywhere near the top after the tray has drained, then that suggests a plumbing fault and not a blockage.

It's clearly not a complete blockage anyway - the water does drain away from the tray. But if the level stops just below tray surface level, then it surely ain't a blockage, or else it would continue to drain away, even if slowly. If it stops near the top, then that suggests that somewhere along the waste, the pipe is also at that height = a mistake, surely?

I think you'll have to remove that section of ceiling again to access the pipework and see what's going on. If it was draining fine before he came, hwe's either fitted a trap that isn't suitable or he's disturbed something else.
