1m run

So this will work ?, there will be enough natural preasure to keep the
flow
running?

I guess that the only problem will be food waste etc. getting stuck at the
"up" point. It's a 40mm pipe BTW.

If I can recess the pipe though I assume this would be better?

Thanks agian......

Can you raise the pipework to the top of the washer and drop it down the
other side. Is there enough room for the 40 mm pipe to run behind the
washer nearer the top of it, say, just under its lid.

To tell you it's OK to start cutting chunks out of your walls, when we don't
know exactly what they are made of, or how they are constructed, would be a
silly thing to do on our part. You say the wall is grey coloured bricks,
but what type of grey coloured bricks are they. Are they thermal blocks,
which are much larger and softer than normal red clay bricks.
