Water Well Pumps – A Buyer’s Guide

Water well pumps can remain operational for many years – decades, in some cases. However, at some point or another, most will need to be replaced.

Residential water wells in Utah and Wyoming typically use jet pumps or submersible pumps. When a pump fails, selecting a replacement can be as easy as installing the same model you already own.

All you must do is identify which type of well pump you have installed and think about the most important considerations for selecting a replacement pump.

Jet Water Well Pumps

Jet well pumps work by pulling water up, and they’re often paired with pressure tanks to store water for household use.

If your pump sits above ground near the wellhead, or if it’s located elsewhere on your property – like in the basement – you have a jet pump. These pumps come in two varieties, shallow and deep. Shallow jet pumps have a single pipe and can draw water from wells that are up to 25 feet in depth. Deep jet pumps have a two-pipe system that can lift water up from more than 100 feet.

Submersible Water Well Pumps

Submersible well pumps work by not by pulling, but by pushing. These pumps, installed at the bottom of the well, may or may not have pressure tanks.

Submersible pumps come in two- and three-wire configurations. You can figure out which type you have by looking for the controls. If you have a control box located inside your home or near the pump housing, it’s a three-wire model. If you don’t see aboveground controls, you likely have the two-wire version.

Choosing a Water Well Pump

Identifying the type of well pump you already have installed is the first step in selecting a replacement. However, just because you can replace your failed pump with the same model you had doesn’t always mean you should.

Many of the newer well pumps available today are much more efficient and have superior features to those installed years ago. With that in mind, you may not want to choose the same pump model.

In addition, older residential wells often have undersized pumps and may benefit from more powerful replacements. That said, going up in size or switching from a jet pump to a submersible pump isn’t always recommended – not all residential wells are constructed to handle additional power.

For expert advice on selecting the right replacement pump, consult with an experienced local well contractor – like the Z-Team professionals at Mike Zimmerman Well Service LLC.

How Deep Does a Residential Water Well Have to Be?

How deep will your residential water well have to be drilled?

Well vs. City Water

This question is important because licensed well contractors charge by the foot for drilling. This means that depth plays a major role in determining the overall cost.

A residential water well can be anywhere from 100 to 800 feet deep – or more. Private wells in the Intermountain West region typically max out at about 200 feet. However, the depth cannot be accurately determined before drilling begins, because several factors influence how deep a well must be to produce an adequate water yield.

Season Fluctuations of the Water Table

Throughout the year, the water table fluctuates up and down due to local groundwater use and precipitation. Drought conditions also affect water table levels. A residential well must be drilled deeper than the lowest likely level to prevent seasonal differences in yield.

Local Surface Contamination Risks

Proper well construction generally provides protection against surface bacterial contamination. In some cases, however, the depth of a residential well is increased to provide a longer flow path of water. The longer the flow path, the greater the likelihood that any subsurface bacteria present will die off or be trapped in the soil and rock.

Low-Yielding Rock Formations

Water well yield can be especially low in areas with hard rock formations, as the impermeable rock acts as a barrier to groundwater flow. To solve this problem, your well contractor may need to drill down further, deep enough to provide a groundwater storage cavity.

Water Quality in the Region

Some regions with multiple aquifers have poor water quality zones that need to be avoided or cased off when drilling a residential well. Otherwise, the quality of the household water may be compromised. Bypassing these zones may mean increasing the well’s depth.

Local Water Well Regulations

Building codes and construction specifications and standards vary by state and licensed well contractors have to follow the local requirements and drilling guidelines. Along with rules regarding location, pump installation and well development, the depth of the well, casing and grout may be regulated.

Are you planning on drilling a new residential water well in Utah or Wyoming? The depth will depend upon the geology and groundwater levels in your area, but the Z-Team professionals at Mike Zimmerman Well Service LLC can give you a cost estimate based upon our 30 years of experience drilling commercial and residential wells in the Intermountain West region.
