Well Pump Systems



Connecticut Basement Systems Radon Inc.(CBSR) is a full service well water system provider.  We handle all phases of well work from pump and pressure tank replacement, to system upgrades and casing extensions.  We are a state licensed plumbing and piping contractor and we offer 24 hour emergency service.  Couple this with our extensive water treatment and radon knowledge and you have an unbeatable combination of abilities.

A well system consists of a pump, pipe, wire, and pressure tank.  The pump delivers water to the pressure tank, the tank in turn delivers pressurized water to points of use within the structure.  A properly sized system should be able to deliver water to the structure under normal usage conditions at reasonable pressure (30 - 60 psi).

There are two basic types of pressure tanks.  Hydro-pneumatic where the air mixes with water within the tank, and bladder/diaphragm where there is a physical separation between the air and water.  Regardless of type, there is a preset amount of air in the tank.  As water enters the tank it compresses the air.  The air acts like a spring and pushes the water out of the tank to points of use in the structure.  When these tanks loose air or become waterlogged, they make the well pump turn on and off more frequently.  This is called "short cycling".  Short cycling sends many a well pump to an early grave.  This can also happen when the tank is in perfect working order but is improperly sized for the application.  Bladder tanks are the newer generation of technology and tend to be less problematic.  This can become especially evident if there are any water quality issues...as air mixing with untreated water can sometimes cause problems.  We can change out most any hydro - pneumatic to a diaphragm type...or upgrade an undersized tank to maximize your system efficiency.


This is the newest innovation in pumping technology for well systems.  A common complaint amongst private well owners is the inability to use  more than one outlet at a time without a substantial loss of pressure.  
Variable speed pump systems enables  water usage at multiple points within the home simultaneously, while maintaining constant pressure.  Some existing well pumps can be easily converted in the field (without pulling the pump).

Variable speed well systems essentially rely on a controller that senses water flow.  As flow increases, the speed of the pump motor increases to compensate for the increased volume.  This transfers to even pressure at all points of use.  This phenomenon is often termed; "city like pressure"... as a large portion of city - supplied home have good pressure. 

With that said, we have also installed variable speed booster pumps for some customers on city supplies who do have pressure problems.  These booster pumps can also be used in homes that have well water and have poor pressure due to treatment systems.  The pump can be installed after the treatment system to repressurize the water to compensate for any drop that may have occurred through the system.


There are two basic categories of well pumps; submersible and jet.  The difference is readily identifiable by the fact that a jet pump is located above ground either in a pump room or basement.  A submersible pump is actually located in the well submerged in water.  Submersible pumps have many advantages over jet pumps.  Better pressure, no operational noise, no loss of prime potential, and a greater ability to prevent contamination from surface seepage since the casing typically extends above grade verses in a sub-surface pit.We can convert your jet to a submersible setup and also install a casing extension so that the well will be compliant with all current codes.


Older wells will often times include a well head that is below grade.  There is a greater potential for contamination of the well in this situation.  This does not meet current codes which call for a well head to extend a minimum 6 inches above grade.  The reason for this is to help prevent contamination from surface runoff.    CBSR is a state licensed contractor for well casing extensions.  We can bring your well up to code by installing a pitless adapter and an extension on the casing to raise it above grade and install a high quality well cap.  This is especially convenient to do when converting from a jet pump to a submersible.


We offer all phases of well system testing from basic flow rate to well depth and recovery rate.  Knowing the particulars of how your well functions under normal conditions can be helpful when trying to access problems that occur, or when considering modifications such as adding an irrigation system, or bathrooms etc.
