Well Pumping System – Part 3

Well Drilling, Well Maintenance Comments Off on Well Pumping System – Part 3


Well we have covered the basics on where to drill & how to drill. In part 3 we will cover the pump system and in part 4, Kirk (our water treatment specialist) will cover the basics of water treatment for a typical residence on well water.


So, let’s dig into the basics about a typical pump system for a residence.


The first thing to consider is how much water the well makes. If your well doesn’t make more than enough water then you may be limited by the amount of water you can pump. In that case you will simply pump as much as you can without over pumping the well. This is not usually the case in central Indiana, but if it is we have options of installing larger storage tank systems and or equipment that can protect your pump from dry running.


Now if your well makes plenty of water (more than enough preferably) we have the liberty of selecting the ideal pump system for the home. There are basically 2 types of pump systems. There is the standard pump system that uses a larger pressure tank and a standard 4″ submersible well pump. This is the old standard that was installed every where in Indiana from the 1960’s to the late 1990’s. These are very dependable systems and are still being installed today; however in most new home situations families in central Indiana tend to go more commonly with the SQE or “Constant Pressure System”. This system has not only proven itself to be dependable, but it boasts city water pressure as well. It has gained popularity because people can take several showers at the same time, or shower while someone is doing laundry or irrigating. Here at my house we run 3 showers simultaneously almost every weekday. The constant pressure pump system produces pressure and volume much like (and even better than) city water pressure.


Usually we start recommending the constant pressure if the square footage of the home is greater than 3500 OR if the home will require open loop geothermal, irrigation or high volume showers.

Next we consider the horse power of the pump. When selecting a standard pumping system keep in mind that the larger the pump, the larger the tank. When you think of the horsepower this is what we increase to increase the volume or gallons per minute (or to pump from deeper levels if the well is unusually deep).

For a home that is less than 2500 square feet with no irrigation or other high flow needs we are typically fine with a standard 1/2 horse power pump system.

For a typical home in the 2500-3500 square foot range with no irrigation or other high flow needs we recommend one of the 3/4 horse power pump systems. Either standard or constant pressure. Whatever you, the homeowner would prefer.

Once we start recommending pump systems for homes in the 3500-4500 square feet with no high flow needs we like the 1 horse power constant pressure pump system.

4500-6000 square feet with moderate irrigation, a high flow shower or a lot of people we tend toward the 1 1/2 horse power constant pressure pump system.

For houses larger than 6000 square feet we like to recommend either the Grundfos 3 or 5 horse power constant pressure pump system. We will usually look at these homes individually to insure we have all of the needs accounted for.

These are good rules of thumb and obviously do not take unusual circumstances into consideration, but will typically get you right in the ballpark.

Our pump systems all come with a 10 year limited warranty, and we use only the best brand name products installed by our licensed, trained water well professionals.

We at C&J pride ourselves on delivering pump systems that take a licking and keep on ticking. They typically outlast the amount of years our customers stay in the homes that we install them in by far.

So, whether your house is large, small or in between we have just the right combination of pumping equipment for your needs.
