No one here thinks that the problem is caused by the mass of water that needs to be accelerated when the pump starts? That the initial surge of torque in the pump needs to get the mass of water between the pump and the tank in the house moving, thus the reason for the higher pressure (seen at the tank) at switch-on? |
