How have you found the water pressure in a large 45+ sqm house with 3-4+ showers?
I tried turning all the water tapes and shower in the house and some of the outlets were barely trickling out water ?
I assume this is upstairs were you have issues?
What happens when some are shut off?
You would think that the dams are higher than the house height to provide pressure to all taps to flow.
What do you do in that situation? Install some electric pump to restore the pressure?
