Generally, the ideal pressure for well water is two pounds less than the start pressure of the water pump. In order to maintain ideal water pressure for a well system, the well must also have a proper pressure tank.
The key to maintaining long-lasting water pressure is to install an appropriately-sized pressure tank for the well. The pressure tank must be of proper size to meet the demand put upon the well. A tank too large can result in fewer cycles, which can lead to uneven water pressure and waste. Conversely, a tank too small can lead to more demand on the water pump itself, leading to shorter pump life.
