Well water systems and how they work

More From Home.

Directly behind the jet is a Venturi tube that increases in diameter. If your home uses more than the average amount of water or has a well with a low yield, a larger pressure tank may be needed.

At the jet, the increase in water velocity creates the partial vacuum that draws standing well water into the second pipe and then back into the pump and plumbing system. This horizontal pipe joins the well pipe at a connector called a pitless adapter. Neither Delaware, Maryland nor Virginia allow a well to be buried. Pressure Tanks As the name implies, a pressure tank contains water under pressure. In order to provide consistent water pressure at the fixtures, the pump first moves water to a storage tank.

Surprisingly, you can still do it with a jet pump.

How It Works: Water Well Pump

Even small villages often provide a network of supply pipes that transport water to each home in the neighborhood. However, silt, sand, algae and other contaminants can shorten the pump's life. Click here to view our constant pressure system. Type keyword s to search. How Do I Get It?

Please contact us regarding the specifics of permitting requirements for your state. Before construction begins, the best location on the property should be identified by considering the location of proposed or existing buildings, septic systems, buried gas or power lines, future building and construction and any other potential sources of contamination.

When landscaping your yard, keep the top of the well at least 1 foot above the soil surface. The impeller moves water, called drive water, from the well through a narrow orifice, or jet, mounted in the housing in front of the impeller.

A pressure switch starts and stops the pump at the preset pressure levels, and allows the system to work automatically. As water is pumped from the well into the pressure tank, it compresses the air in the tank until it reaches a preset level, typically the 40 to 60 pounds per square inch psi. Without these features the water pump would turn on and off quickly — a problem caused cycling — which can quickly burn out the pump motor.

As the water leaves the jet, a partial vacuum is created that sucks additional water from the well.

Shallow well jet pumps — which are used where the water is less than 25 feet below the surface — have the jet located in the pump itself.
