Our bathroom has had a double trap syphonic loo for many years and now it's time to re-fit the bathroom.
We've always apperciated the fact that it's very quiet in operation and that it clears waste at the first attempt every time. We often notice that when visiting other houses, modern loos don't always succeed in properly emtying first time, or even after a second flush.
Naturally we would prefer to replace it with a similar one, but our local bathroom centre told me that they use too much water and are no longer allowed in the UK.
Is this true ?
is there any way of finding out before you install it, just how efficient a particular loo might be at clearing waste ?
