I also looked at this recently as I thought that soap would be harmful to plants and/or microbes and the Royal Horticultural Society has done some investigation of their own into the use of greywater, and their advice is “plants can be watered with shower, bath, kitchen and washing machine water (from rinse cycles)”, finding that “soil and potting composts are effective at filtering out” the soap/detergent.
I’m just echoing @Denjin@feddit.uk with the RHS link, and I didn’t read the articles he linked but it wouldn’t surprise me if the RHS guidance is the source of those.
I wonder if I would need a pump or could connect a tube directly to the bathroom tap/shower outlet at the side of my house. It is only elevated slightly above the ground, it looks like the path is flat but there could be a slight gradient either way that I am unaware of. Kitchen outlet for the washing machine and kitchen sink is a bit higher. But I think the bathroom water is a cleaner source.
Either way its something to look into trying. Pipe probably doesn’t cost much to experiment with and can be removed when not needed. Worst thing that would happen is the shower fills up and you notice that pretty quickly, then just take it off.
pumps are cheap enough but they probably increase the chance of blockage due to hair and so on. if you could get it using just gravity it would prob be better from a minimum maintenance viewpoint.
