What causes low water pressure in one house but not the house next door?
Answers:
Every house has a pressure regulator to control the high pressure from the water main. Yours is set too low. If you can find it you turn the center screw clockwise to increase pressure. Trial & error is the best way to decide where you want it.

I just experienced the same problem, we changed most of the faucets in our home and the screens that prevent the water from coming out and it improved it a little
two reasons.most houses share a main water feed were i live one main feeds 8houses .if the first houses on the main feed the pressure in the other houses is low..the other reason could be an underground leak before it gets to the house.causing a low pressure in the house water supply.i hope this helps
May be obvious, but check that your main shut off valve isn't partially closed. After working on an apartment before we had the complaint and found that was the problem
maybe a broken pipe from winter time!
low water pressure can be caused by the wrong sized pipes.
