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


Yes, see http://www.bathstore.com/pumps.asp, especially "Whole house
pumps".


ObGripe: The company's called "bathstore.com" but if you put that into
your browser, you get "Page not found". To get to their site you need to
put "www.bathstore.com". Doesn't give you much faith, does it?



(i) flow ios a funcion of pressure and bore, the more of either, the
bigger the flow.

(ii) adding a pumpo will work UP TO A PO*INT.

(iii) THAT POINT is when the flow hrough teh mains supply frim teh water
company exceeds the pressure with which they sup[ply it, and teh dameter
of their pipe.

Or to put it another way, their supply is at a certain pressure, and
just e.. taking teh tap off teh mains supply and letting it gush is
*almost* as fast a flow rate as you can get. Addoung a pump can lower
the pressure at your end of the pipe to (almost) 0, from 1 bar. but not
any more.

So if the water mains can't do the flow rate, no amount of pumping is
going to help on the suction side of the pipe. You need a pump at the
water companies pumping station :-) Or a bigger pipe from them.

To put it another way. A pump can remedy deficencies in YOUR plumbing,
but not the water companies...or only a bit anyway.
