I have done a rough flow rate calculation using the cold tap at the
bath -
I calibrated an orange B&Q builders bucket at 10 litres up to the
spout,
then counted 'one and two' etc. as I didn't have two extra hands to
work
the stop watch. It takes about 10 seconds to fill a 10 litre bucket
including the turn on time so flow should be at least 60 litres per
minute.

Invalid for flow rate. Measure at kitchen cold tap, at 9 am,12.00 and
6pm to get a clearer picture.

Measure at biggest mains fed tap - taps can be restriction

Exactly - which is why I used the bath tap :-)


You said you have a tank/cylinder arrangement. Is that off the cold water
mains? 60 litres/min appears excessive.


I prefer to think of it as impressive :-)

As posted higher up, I have checked and it is from the mains.
