I've messed up. I ran a new waste for the basin to the soil stack. I've since installed plasterboard and and tiled over the wall. Now it has come to fit the sink, it seems I brought the waste out too low.



What's the best way to overcome this? Even with the adjustable bottle trap I can't get it low enough to align.

Any help greatly appreciated.

I just thought the same. I was always under the impression it’s better to have that quite low then too high up. Very often you get called out for a sink blockage or whatever reason and you see that you have got difficulties to put a proper trap in unless you install a waste and ripping the whole lot out.

Unless the trap hits the board beneath it, extend the inlet pipe and lower the trap. If it does, can you lower, or remove, the board?
 
I would use solvent weld elbow/pipe/elbow to bring it up; then use a p-trap , which gives you much more flexibility of fit as you can articulate the two sections to suit.
Not really a problem here, try it when you’ve brought the new pipe in too high - doh!

Pop Up Waste Suits Overflow & Non-overflow Basins
Hi Everyone, I recently brought a replacement Pop Up Waste from Argent K316-DL & the spec states it suits both overflow & non-overflow basins. However it has no slotted waste opening. How could this be used with sinks with an overflow hole & still prevent sink overflow? Thanks Natalie Argent...
