A small (50- to 60-gallon) storage tank is usually sufficient for one to two three people. A medium (80-gallon) storage tank works well for three to four people. A large tank is appropriate for four to six people. There is no such thing as a pressure tank that's too large. And, because larger pressure tanks have fewer pump cycles, it can increase the life of your pressure tank. If your tank is waterlogged, that means that there is too much water and too little air in the tank. The rubber bladder inside the tank expands and contracts to keep water and air separate inside the tank. When this bladder ruptures, the water and air are no longer kept separate, and the pressure inside the tank drops. Your well tank's pressure should be set at 2 psi below the pressure switch's cut-on point. This differs depending on your tank's pressure settings. Most well tanks come set at 30/50. The cut-on pressure for the well pump is 30 psi, so the pressure of the tank should have a pressure of 28 psi. When water is pumped into a tank containing air, the air is compressed, putting the wate r under pressure. The more the air is compressed, the greater the water pressure. When the water reaches a preset pressure, typically 40 to 60 pounds per square inch (psi), the pump automatically shuts off. Both these 10000 litre water tanks, when full, exert 10000 kilograms or 10 metric tonnes of downward pressure (assuming 1 litre of water weighs 1 kg). When the low setting is reached the pressure switch tells the water pump to turn on and more water is pushed into the tank and house. The bigger the tank you have the larger the drawdown (actual amoun When the low setting is reached the pressure switch tells the water pump to turn on and more water is pushed into the tank and house. The bigger the tank you have the larger the drawdown (actual amount of water stored) you will have. A larger drawdown means longer run time and therefore less cycles.
