Well Pumps & Well Tanks
Your well system is made up of a well pump, a well storage tank, and various accessories that operate the system automatically. It is important to have a professional monitor and install all aspects of your well system to ensure everything is working properly.

About Well Pumps
The well pump raises water from your well and delivers it to a well storage tank. It stays there, held under pressure, until you need it to wash dishes or take a shower. The pump refers to both the pump and the electric motor, which together make up the pumping unit.
There are many different types of pumps for water systems. Some are designed to remove water from a source, while others are made to force water through the rest of the your water system.
Pumps vary in sizes and type, too. Pump sizes include shallow-well and deep-well. Jet pumps and submersible pumps are the most common pump types. Selecting the appropriate pump size and type is a critical step in the design of your water well system. The size of your well pump is based on the yield of your well and the needs of your household. The pump must meet normal peak demand for the household, rather than average use. If your pump installation is not properly planned, you won't receive satisfactory water delivery.
One general rule is to never install a pump that has a greater capacity than your well, unless you need to use well storage, along with well yield, to meet your peak demand for water.
If the peak demand exceeds the maximum rate of water available, the pump must be sized within the well capacity and the peak demand reached through added storage. Usually a large-size pressure tank can perform this function.
About Well Tanks
The well tank stores the water delivered to it from the well pump. It remains there, under pressure, until your turn on a faucet. In a pressure tank, compressed air in the tank acts like a coiled spring, pushing the water in the water chamber. If no water is being used, the well tank will continue to fill until the pressure reaches a set point, usually 40, 50 or 60 pounds per square inch (psi). A pressure switch then signals the pump to stop.
When a valve is opened in your system, such as a kitchen tap, air pressure in the tank forces the water to flow out of the well tank and into the pipes. The pressure falls as the water flows out of the tank. When it drops to the start-up setting of the pressure switch, usually 20, 30 or 40 psi, the pump starts again until the well tank is filled.
There are three main types of ANSI-approved pressure well tanks: diaphragm or bladder tanks with a complete separation between the air and water; plain tanks with a float or wafer separating air and water; and plain steel tanks. Your well professional can determine which well tank to use based on your well yield and your household water needs.
