These days, many homeowners are struggling with the idea of "going off the grid." While the prospect might seem attractive at first, some of the innate challenges begin to poke out once the real planning begins. However, one decision which can be easier than others is the idea of having a personal water supply by digging a well and installing a pump. The first obstacle, then, is choosing a pump based on location, depth of the water table, and other factors. This process is easier than most people realize, as there are only a few criteria to consider when choosing a well pump.
Shallow Well Jet Pumps
As is implied, these types of pumps are used for wells that are 25 feet deep or less. The way these pumps work is by using suction to pull the water up past the pump itself and into the storage tank. Therefore, atmospheric pressure is used to push down on the water already in the well, so more water can be sucked up into the pipes of the system. It is for this reason that these types of pumps are not recommended for very high altitudes.
Deep Well Jet Pumps
These types of pumps are also called "two line jet pumps" because they typically incorporate two pipes in their design instead of the single-pipe system described above. These pumps can be used with wells deeper than 25 feet, up to about 90 feet, and they work by forcing water down into the well using a small-diameter pipe and sucking more water up into a pipe of a larger diameter, which becomes your home's water supply. Due to the nature of the system, it is then important to keep your pump primed so that it can shoot water down into the well in order to suck more up. This can become a maintenance issue, so be sure to ask about this process when installing your well pump.
Submersible Well Pumps
These types of pumps are recommended for the deepest of wells, from 90 feet to 300 feet deep. The way these pumps work is much simpler than the other two pumps described, as it only uses the pump itself to suck water. Water is drawn in through an entrance and sent through a set of impellers, which then shoot the water up the pipe in the well. One thing to consider in choosing a submersible pump is whether to purchase a 2-wire or 3-wire system, with the third wire allowing for use of a control box, which can be useful in the event of a malfunction.
Installing a water well is a huge step towards total independence from municipal utilities for your home, and thankfully the process is fairly simple to break down and assess based on your needs and your environment. Digging and operating a well might just be the most important choice you make for your home this year, and choosing your pump is a cinch!
