Well Pumps & Pressure Tanks
Every well system consists of a well pump and a pressure tank as they work together. In simple terms, the well pump draws water from your well and the pressure tank disperses the water to your fixtures.
Water Pressure Tanks
Found in the basements of homes on water wells, this tank creates water pressure by using compressed air pushing down on the water and are regulated by a pressure switch. The switch senses pressure and will turn off to protect your fixtures. Because your well does not have positive pressure, it requires help to pressurize the water causing it to move throughout the water pipes of your home. There are different sizes of tanks but selecting the correct size for your home will reduce the risk of premature pump failure.
Installation of Water Pressure Tanks
We at Honest D Plumbing believe in installing the best quality equipment and in the case of pressure tanks, we use fiberglass tanks which don’t rust out like the galvanized or steel tanks tend to. If you notice when you turn on the taps of your home and the pressure doesn’t seem to be very strong, you may want to consider turning up the pressure slightly. Be careful not to turn it too high otherwise it will damage your fixtures. An average psi setting for a pressure tank in your home can be anywhere from 20 – 60 psi.
The Two Different Types of Well Pumps Are Commonly:
Submersible Pumps are electric pumps located inside your well placed a short distance from the bottom to avoid the intake of sediment. They push the water to the surface whereas Jet pumps create a vacuum and rely upon suction to work. Submersible well pumps are cylinder-shaped and are typically the size of a baseball bat and are often regarded as more efficient than Jet pumps.
Jet Pumps are typically used in a shallow well situation and work by creating a vacuum in the suction pipe and as mentioned above, rely on atmospheric pressure to force the water from the well to the pump. The jet pump is usually located inside the basement as opposed to inside the well as in the case of a submersible pump. Often times jet pumps will be placed beside the pressure tank as shown in this picture.
