There are a couple of points that you might like to consider:

1. I do not believe that you are allowed to suck water from the mains -
after all that might result in air being drawn into other people's taps.
2. Low flow rate isn't necessarily associated with low water pressure. If
you have a long feed between the stopcock and your house that is small bore
and perhaps furred up then the pressure might be good but the flow will be
limited.

Southern Water will do a free check of the water pressure at the stopcock
and at your kitchen sink. Possibly your water board will do the same. I
think that they are obliged to ensure that the pressure is good at the
stopcock but they are not responsible for the pipe between there and your
house.

If you decide on implementing the header tank/pump scheme, I would suggest
that you do go for a shower pump. They have integral switches that detect a
small flow (resulting from the header tank) when you turn a tap on. This
small flow activates the pump. You can also get double pumps, of course, so
you could pressurise the hot as well as the cold system. Using one of these
pumps would also protect you from the possibility of damage when/if the
header tank empties. If this should happen the flow would cease and so the
pump would switch itself off and therefore protect itself.

is it possible to add a pump to increase waterpressure & flow? similar to
a
shower pump for the whole house?
