I find that having installed a new toilet with a 6 litre flush I am having
to occasionally rod the drains. I have had the drains power flushed and
inspected with a camera and they are ok.. Having lowered the amount of water
in flush has their been any changing of the regulations regarding how the
drains are laid.

I didn't have the inspection, but I had the same experience with old
drains (porcelain on a 50m run to a septic tank). Installed a toilet
with low flush for fluids and 6 months later the system blocked and
took probably more water than had been saved to get the drain to
clear. I disconnected the low flush and haven't had any bother since.

I do wonder whether in the final analysis, the modern plastic drain
with its almost seamless joints is better than porcelain in the end.

Yes, almost certainly.

I don't know about absolute lifespan, but certainly in terms of
intervals between clearance of major blockages. And it's virtually
impervious to root penetration, too.
