Have been looking for ages for a kitchen mixer tap.

Almost every one which is otherwise acceptable demands a water pressure
of 1.0 bar or higher. We'd struggle. Mains cold is fine, but open system
HW with, perhaps, a five metre head would struggle.

We do have mixers on upstairs and downstairs basins - and they are OK.
But I think I remember searching out ones which claimed to work at lower
pressures.

How bad would it be to use a 1.0 minimum tap?

There is a definite pressure (ha ha) to get one that is white. Already
cuts down the available products by over 95%.
