Not sure if it's also a regulation that dual flushes are fitted.

ISTR the history of washdown pan regulations is:

1) dual flush permitted/encouraged

2) better design allows a "small" flush to clear the pan

3) dual flush not permitted, other then as a replacement

AFAIK double and single trap syphonic pans are permitted, provided
they use "modern" flush quantities.




It's pointless anyway - if the first flush doesn't do the job, one just
flushes again (and again) which is less efficient in terms of water use.

Being devil's advocate...

So what happens if your loo is supplied with reprocessed grey water?

Look like it's time to take a course in bronze casting and make me own
cistern, the way things are going.
