I have a well and the water pressure is very low, especially on the 2nd floor where the showers are. It affects the dishwasher as the dishes usually don't come out clean. Is there any possible fix for this? The house is a bit over 50 years' old and has steel pipes. The well and pump are new (within the last 2 years). The low water pressure also exists in the basement (washing machine) which is very near the point of entry and near the holding tank.
