Tidying up external pipework

[SamHLM]

I'm looking at replacing these waste pipes (leaving the soil stack as is) to give it all a tidy up.

Is there a way of connecting anything differently to make it look better or would it be better just to replace like for like?

Start by working out whether you have separate rain water, from soil water drains severing your property, or if you have a combined sewer system.

You could combine the bathroom wastes into one pipe and run it and cut into the main cast via a boss. The lower sink could also be combined into the cast using another boss but you will always be left with the pipework spans unless you can run some of it internally.
