Well Testing

Overview of what to expect with a System Inspection, Well Test and Water Potability Test

System Inspection
A system inspection is conducted to assess the overall condition of a pump system and uncover any issues that may be of concern for anyone considering the purchase of a property or an overall evaluation of the health of a pump system.

During system inspection, technicians will evaluate all components of a pump system. Starting with the electrical controls and wiring, to the pressure tank and related plumbing infrastructure up and to the pressure tank. All physical components that are accessible are visually inspected for any deficiencies including the well head to make sure it is in a sanitary condition and location. We DO NOT pull the well pump out of the well for a system inspection.

Additionally, our technicians will perform electrical tests for shorts to ground in the system and check for continuity of the motor windings. Finally, they will run the pump system under normal operating conditions and monitor the motor current (amps) to check that the system is performing properly before conducting a flow test.

This may uncover any deficiencies in the system that would prevent conducting the well/flow test.
A system inspection is performed before a well test is conducted. During a system inspection, if an existing condition is identified that could damage the well or pump system, no further testing will be pursued until well owner and any stakeholders involved notified about the concerning issues.


Well Testing
A well flow test is highly recommended any time before considering the purchase of a property. If a well is unable to supply enough water for future anticipated uses, such as animals, irrigation or normal household usage with a large family, it is advantageous to learn beforehand in order to make an educated decision on property acquisition. A draw-down flow test will determine a well’s actual yield in gallons per minute. The test requires measuring water being pumped out of the well while monitoring the water level as it drops inside the well casing. When the amount of water entering into the well casing matches the amount being pumped out, the results are the true yield of the well.

The only way to know exactly where the water level is in a well as it is being pumped is with a water level sounder. Most sounders are wired meaning a probe is sent down a well on a wire to make contact with water. Typically this is a normal procedure when a pump is removed from a well to obtain well depth and water level. When there is pumping equipment installed in a well, there is a very high probability that the water level probe and wire will get hung up or stuck in the pumping equipment. For this reason, we do not utilize a water level sounder on most well tests unless is it specifically required.

By monitoring the water flow (gallons per minute/gpm) being pumped, system pressure and motor current (amperage), we can gain a fairly accurate picture of the well production without the use of a level sounder. If the water flow (gpm) pressure and amps all slowly decrease as the test goes on, it is obvious the water level is dropping as water is being pumped. This typically happens for the first period of the well test unless the well production matches or exceeds pump production. If the water flow (gpm), pressure and amps all level out and stay steady after a period of time as water is being pumped, the production rate of the well is in excess of the amount of water being pumped out.

Another reason for having well test would be to check for sediment in the water as it is being pumped. Typically if a well produces sediment or has a high mineral content, it will become apparent during the test and may or may not be an indication of a bigger problem. Some wells produce sediment or have naturally occurring minerals. By visually checking this during a well test, an assessment can be made on whether or not it will have the potential to become an issue. In some cases there is a filtration element in place to mitigate the minerals and sediment. Realizing this is something to monitor and maintain is good information to have.

We offer both a 1hr or 2hr well test, depending on a lenders requirements. Some lenders will require a 2hr minimum test. When there is no required minimum, it will be optional after 1hr of testing whether to continue the test or not. This is usually determined onsite based on what the results are with the test up to that point. If it appears that the water level is lowering in the well as it is pumped, it may be prudent to continue the test to determine a stable production rate or run the well out of water and determine the production rate at that point. If all factors appear to be stabilized (flow, pressure, amps) after 1hr, it will indicate well production to be approximately what the pumping rate is and negate any further need to continue pump testing.

Water Potability Tests
Determining if a water well is free of bacteria, safe to drink and use is of utmost importance. Testing well water at least once a year to ensure health and safety is a good practice. Water potability tests can be obtained through the El Paso County Health Department and/or Barnhart Pump Company. We offer water sampling service to ensure procedures are done correctly as any contamination can render a failed test if not done properly.

Scheduling Your System Inspection, Well Test or Water Potability Test and Required Documentation


Before we can perform any or all of these services, we require our Liability Release Form be signed by the homeowner/well owner acknowledging and granting permission to carry out testing procedures. This form also releases Barnhart Pump Company from liability should any part of the pump system fail while testing the system. It may seem unusual to require a release of liability, however, mechanical parts do wear out and can fail at anytime: while doing a load of laundry, watering the lawn and even during well testing. It is important to understand that well testing like every day use of the well can cause mechanical/electrical devices to break down.

Once the Liability Release Form has been signed by the well owner, a service call can be scheduled to perform well inspection and/or testing.***The Release Form must be signed and returned 24hrs in advance of scheduled appointment, otherwise the inspection and/or testing will be rescheduled once the form is received. After the inspection and/or testing is complete and payment has been made in full, a copy of the detailed inspection report and flow test will be sent via email in PDF format. Water Potability Test results from the county will also be sent via email as soon as results are available, which is usually by the next morning.

We welcome any party involved in a real estate transaction, whether it be a buyer, a seller, agent, etc., to be onsite during testing to ask any questions or learn more about how a water system works for peace of mind in the process.
