WELL TEST FAQ
Q: What is the well pump’s primary function?
A: The well pump’s function is to provide water from the underground aquifer (a body of permeable rock that can store or transmit groundwater) to the house via the well system.
Q: What does “submersible” mean?
A: “Submersible” means the pump is submerged in water inside the well. It is located toward the bottom of the well and pushes water upward to the house.
Q: What is a jet pump?
A: A jet pump is a type of pump located above ground, usually in a basement or utility room. It pulls water out of the well and into the house.
Q: What does “HP” mean?
A: “HP” stands for horsepower, a unit of measurement for power. One horsepower equals 550 foot-pounds per second or 745.7 watts.
Q: What does “2-wire” or “3-wire” mean?
A: This refers to the wiring configuration of the well pump. A 2-wire pump includes two hot wires, while a 3-wire pump includes two hot wires and a control wire. This information helps determine the pump’s wiring setup, running amperage, and the type of pump installed.
Q: Why measure the voltage?
A: Measuring the voltage at the well switch ensures the switch is operating properly and receiving the correct power supply for efficient pump operation.
Q: How do I know if my well pump is failing?
A: Signs of a failing well pump include sputtering, inconsistent water pressure, unusual noises from the pump, or air bubbles in your supply.
Q: What is a pressure tank, and why is it important?
A: The pressure tank stores and regulates water pressure for the home. It prevents the well pump from running every time water is needed, which extends the pump’s lifespan.
Q: How often should I have my well system tested?
A: It’s recommended to have your well system tested annually to ensure water quality and check the condition of the pump and other components.
Q: What is a well casing?
A: A well casing is a tubular structure placed in the drilled well to maintain the well opening and prevent contaminants from entering the supply.
Q: How does a well chlorination process work?
A: Well chlorination involves adding chlorine to the well water to kill bacteria and disinfect the system. It is a common practice after repairs or if contamination is detected.
Q: What is a well cap?
A: A well cap is a protective cover on the top of the well casing. It prevents debris, insects, and small animals from entering the well.
Q: What is the lifespan of a well?
A: A properly constructed and maintained well can last 20–50 years, depending on the geological conditions and the quality of the materials used.
WELL FUNCTION FAQ
Q: Why measure amps?
A: Measuring the amperage allows us to confirm the pump is operating within its appropriate range. Over or under-amping can indicate issues such as pump strain, incorrect wiring, or mechanical problems.
Q: What is the static water level?
A: The static water level is the distance from the ground surface to the water level inside the well. For example, if the static water level is 32.5 feet, the water level sits 32.5 feet below the surface.
Q: What is drawdown?
A: Drawdown refers to the amount of water or time it takes for the pressure tank to empty to the point where the well pump activates.
Q: Why do we test at intervals (e.g., 1 minute, 10 minutes, over an hour)?
A: Running tests at set intervals helps differentiate between the performance of the pressure tank and the pump. The first test measures water from the tank, while subsequent tests evaluate the pump’s performance after the tank is emptied and the pump engages.
Q: What is the significance of “40/60” or “30/50” on the pressure switch?
A: These numbers refer to the pressure range controlled by the pressure switch. For instance:
- 40/60 Switch: The pressure tank is “full” at 60 PSI and “empty” at 40 PSI. The pump activates at 40 PSI to refill the tank and shuts off at 60 PSI.
- 30/50 Switch: Functions similarly, with the tank “full” at 50 PSI and “empty” at 30 PSI.
Q: How deep are most wells?
A: The depth of a well depends on the area’s geology, but most residential wells range from 100 to 500 feet deep.
Q: What happens if my well runs dry?
A: If a well runs dry, it may recover naturally after rainfall, but you may need to reduce water usage or consult a professional to assess the well and water table.
Q: How long does a well pump usually last?
A: A well pump typically lasts between 8 and 15 years, depending on usage, maintenance, and water quality.
Q: Can I increase my water pressure?
A: Yes, water pressure can often be adjusted at the pressure switch. However, it’s essential to consult a professional to avoid damaging the system.
Q: What is water yield, and why is it important?
A: Water yield refers to the amount of water a well can provide over a given period. It’s important for ensuring the well meets the household’s water usage needs.
Q: What is a flow test?
A: A flow test measures how much the well can produce per minute. This helps determine the system’s capacity to meet water demand.
Q: What causes cloudy or discolored water from my well?
A: Cloudy or discolored water could result from sediment, mineral buildup, or contamination. It’s important to test and address any issues promptly.
Q: What is well rehabilitation?
A: Well rehabilitation involves cleaning or repairing a well to restore water flow and improve water quality. It may include removing debris, clearing blockages, or addressing contamination.
Q: What are common well water contaminants?
A: Common well contaminants include bacteria, nitrates, arsenic, lead, and pesticides. Annual water testing helps identify and address these issues.
Q: Can I run out of water with a private well?
A: Yes, wells can run dry during droughts or if the aquifer is overdrawn. Proper management and monitoring can help prevent this issue.
