Wells and Pumps questions, answered by experts

There are many reasons you may want to extend the depth of an existing well or drill a new, deeper well on your property. A deeper well can tap cleaner water sources—shallow water may contain more contaminants. With a deeper well, you’ll also have an easier time reaching the water table depth (the level at which underground water is found) and can get past tricky soil conditions. 

Plus, if your local building code requires a minimum well depth for safety and environmental standards, you’ll meet the code by digging a deeper well in the first place.

Most submersible well pumps last eight to 15 years, depending on the quality, type, and how well they’re maintained. Lower-quality submersible pumps that are poorly maintained will not last very long, but higher-quality pumps can last 15 to 25 years (or even longer). Jet pumps last eight to 10 years.

There are other ways to increase well water pressure. You can often increase the pressure by adjusting the valve on your pressure tank. The pressure issue may be the result of build-up along the pipes or a clog in the system, so descaling and unclogging your system can help improve the overall pressure.

The precharged pressure tank should start at around 28 psi. The two pressure settings of note are the cut-in and cut-out pressure. The well pump starts when the tank reaches the minimum cut-in pressure. It turns off when the tank reaches the maximum cut-out pressure. The desired water pressure in the household is usually a few psi above the cut-in number. The difference between the cut-in and cut-out pressure settings should be 20 psi. Typical settings for household applications include 20/40, 30/50, and 40/60.

Many contractors offer warranties for parts and labor. Confirm terms before hiring.
