presion i ujit

Water pressure is the force that pushes water through pipes and determines the rate of flow from your taps. Water companies are required to provide water at a pressure that will reach the upper floors of houses, but where this is a problem, pressure can be improved using pumps. However, devices such as power showers, which use a pump to boost flow for a more powerful shower spray, also greatly increase the volume of water used and the energy required to heat it.
