Sorry to hijack this thread! We have a MegaFlo tank and the plumbers who installed it used a plastic waste pipe for the tundish overflow. I know it should be copper due to the possiblility of high temeperatures, but where the tank is, it would now be impossible to run a separate copper drain pipe.
Is this a major issue leaving the plastic pipe? I read the specs. online for a similar pipe and they are tested up to 95°C intermittent (hot/cold) and between 70°C - 75°C continuous.
Gray0689 is this what you speak of?
The pipework should not have a resistance to the flow of watergreater than that of a straight pipe 9 metres long unless the bore is increased to take account of the increased resistance.

The test is pretty straightforward. But as for a book I got the corgi unvented hot water and system design guide and found it really useful as a reference when I was first going out on my own. Unusually for a corgi book it's really clear and concise.
Thanks for the replies everyone, encouraging as always.
Think I'll get myself one of those Corgi Unvented books
