Pressurised water system, why?

    Have just moved into a new house with a pressurised water system and every time you flush the toilet the noisy pump (located in the airing cupboard) starts to pump water back into the toilet cistern, and every time you turn on a tap the same thing happens, but why? I can understand the pump being employed for the shower, but why the rest of the house???

    I did turn off the pump recently by flicking the power switch and everything still functioned reasonably well, the cistern still filled (after a bit more time), and the hot taps still worked alright, admittedly without the powerful pump pressure, but they worked none the less. Maybe I can locate some leavers in the airing cupboard & isolate/divert the pump from the toilet & taps? so that it only works for the shower?

    If the toilet and basin are kicking in it sounds like the lazy bugger of a plumber connected the pump wrong.

    Take a picture of the copper cylinder in the hot press and around the top where the pump is connected. It is most likely connected to the expansion pipe which is the lazy way of doing it.

    The problem with isolating the pump is the props in the pump still turn with the flow of the water and as one side is being turned by water and the other following over time it can as suggested by the manufacturers cause an imbalance in the pump meaning its life is shortened.

    This is all a rough assumption without knowing more but based on previous experience i am fairly confident i am right.
