The **hydrostatic pressure** within a well system is a fundamental indicator of its operational health. Understanding what should well pressure be requires careful consideration of factors impacting it, such as the submersible **well pump** capacity and the **pressure tank’s** pre-charge. Neglecting proper maintenance or ignoring the warning signs can lead to system failures, highlighting the critical role that experienced professionals at the **National Ground Water Association (NGWA)** play in ensuring safe and reliable water access.

Well Pressure Explained: A Guide to Optimal Performance and Potential Issues
This guide offers a comprehensive breakdown of well pressure, focusing on the ideal pressure range and how to identify problems that might arise. Understanding these aspects is crucial for maintaining a reliable and safe water supply.
Understanding Well Pressure Basics
Well pressure refers to the force of water being delivered from your well to your home. It’s measured in pounds per square inch (PSI). The proper pressure ensures that you have sufficient water flow for showering, washing dishes, and other household needs. Too little pressure results in weak flow; too much pressure can damage your plumbing.
The Role of the Pressure Tank
The pressure tank is a key component in your well system. It stores water under pressure, providing a readily available supply. It minimizes how frequently the well pump needs to cycle on and off, extending its lifespan and saving energy.
- The tank uses compressed air to maintain consistent pressure.
- As water is used in the house, the air pressure in the tank pushes the water out.
- When the pressure drops to a pre-set "cut-in" point, the well pump activates to refill the tank.
- The pump continues to run until the pressure reaches a pre-set "cut-out" point.
What Should Well Pressure Be? The Ideal Range
Determining "what should well pressure be" depends on your specific system setup, but a general range is widely accepted.
Recommended Pressure Range
Generally, a well pressure range of 40-60 PSI is considered ideal for most residential applications. This range provides sufficient water pressure without placing undue stress on plumbing fixtures and appliances.
- Cut-in Pressure: This is the pressure at which your well pump starts to refill the pressure tank. A common cut-in pressure is 40 PSI.
- Cut-out Pressure: This is the pressure at which your well pump shuts off after refilling the tank. A common cut-out pressure is 60 PSI.
Adjustable Pressure Settings
Many pressure switches allow for some adjustment of the cut-in and cut-out pressures within a limited range.
- Consider your needs: If you experience consistently low pressure, you may be able to slightly increase the cut-in and cut-out settings.
- Proceed with caution: Increasing the pressure too much can strain your plumbing and shorten the lifespan of your pump. Consult a qualified well technician before making significant adjustments.
Critical Warning Signs of Well Pressure Problems
Identifying potential issues early can prevent costly repairs and ensure a safe water supply.
Low Water Pressure
Low water pressure is a common symptom of a variety of problems.
- Symptoms: Weak water flow from faucets, showers, and appliances; difficulty filling bathtubs or washing machines.
- Possible Causes:
- Failing Well Pump: The pump may be wearing out and unable to generate sufficient pressure.
- Clogged Well Screen or Pipe: Mineral deposits or sediment can restrict water flow.
- Water Leaks: Leaks in the well casing or plumbing system can reduce pressure.
- Pressure Tank Problems: A waterlogged pressure tank (too much water, not enough air) won’t maintain proper pressure.
Fluctuating Water Pressure
Inconsistent water pressure can indicate issues with the pressure tank or pump.
- Symptoms: Water pressure that surges and drops intermittently.
- Possible Causes:
- Pressure Tank Problems: Could point to a failing air bladder within the tank or an incorrect air charge.
- Pump Short Cycling: Rapid on-off cycling of the pump, often caused by a waterlogged pressure tank.
- Faulty Pressure Switch: A malfunctioning pressure switch can send incorrect signals to the pump.
High Water Pressure
Excessively high water pressure can damage your plumbing system.
- Symptoms: Loud banging pipes, leaking faucets, and increased risk of burst pipes or appliance failure.
- Possible Causes:
- Faulty Pressure Switch: A stuck or malfunctioning pressure switch may fail to shut off the pump at the cut-out pressure.
- Incorrect Pressure Switch Settings: If the cut-out pressure is set too high.
Other Warning Signs
These additional signs might point towards a problem with the well and its pressure.
- Dirty or Discolored Water: Sediment or rust in the water can indicate issues with the well casing, screen, or pump.
- Air in the Water: Air bubbles in the water, especially when the well is first turned on, can suggest a leak in the well casing or suction pipe.
- Unusual Noises from the Well or Pump: Grinding, squealing, or banging sounds can indicate pump failure or other mechanical problems.
Troubleshooting and Maintenance
Regular maintenance and prompt troubleshooting are essential for maintaining optimal well pressure and extending the life of your well system.
Checking the Air Charge in the Pressure Tank
- Procedure: Turn off the well pump, drain the tank completely, and use a tire pressure gauge to check the air pressure at the Schrader valve (usually located on top of the tank). The air pressure should be 2 PSI below the cut-in pressure of your pump (e.g., 38 PSI if your cut-in pressure is 40 PSI).
- Action: If the air pressure is low, add air using an air compressor. If the tank is waterlogged and unable to hold air, it may need to be replaced.
Inspecting the Pressure Switch
- Visual Inspection: Check for signs of damage, corrosion, or water leaks.
- Professional Testing: A qualified technician can test the pressure switch to ensure it’s functioning properly and accurately sensing pressure changes.
Regular Well Maintenance
- Water Testing: Periodically test your water for contaminants, especially if you notice changes in taste, odor, or appearance.
- Well Inspections: Schedule regular well inspections by a qualified well contractor to identify potential problems early. These inspections can assess the condition of the well casing, pump, and other components.
Table Summary: Problems, Symptoms, and Causes
| Problem | Symptoms | Possible Causes |
|---|---|---|
| Low Pressure | Weak flow, difficulty filling fixtures | Failing pump, clogged screen/pipe, water leaks, pressure tank problems |
| Fluctuating Pressure | Surges and drops in pressure | Pressure tank problems, pump short cycling, faulty pressure switch |
| High Pressure | Banging pipes, leaking faucets | Faulty pressure switch, incorrect pressure switch settings |
| Dirty/Discolored Water | Sediment or rust in water | Well casing/screen problems, pump issues |
| Air in Water | Air bubbles | Leak in well casing/suction pipe |
Disclaimer: Always consult a qualified well technician for diagnosis and repair of well system problems. Improper repairs can damage your equipment and contaminate your water supply.
Well Pressure: Your Burning Questions Answered
Here are some common questions about well pressure to help you keep your system running smoothly.
What is considered normal well water pressure?
Typically, well water pressure should be between 40 and 60 PSI (pounds per square inch). Some systems operate slightly outside this range, but staying within these limits generally ensures adequate water flow while preventing damage to your plumbing. A pressure tank helps maintain this consistent pressure.
What causes low water pressure in my well system?
Several factors can lead to low well pressure. These include a failing well pump, a clogged well screen, leaks in your underground pipes, a waterlogged pressure tank, or a drop in the well’s water level. It’s important to investigate these potential causes to restore proper pressure.
What are the warning signs of too high well pressure?
High well pressure, typically above 80 PSI, can damage pipes and appliances. Warning signs include banging pipes, dripping faucets, and prematurely failing appliances like washing machines or dishwashers. Addressing high pressure promptly prevents costly repairs.
Is fluctuating well pressure a cause for concern?
Yes, fluctuating pressure often indicates a problem with your pressure tank. The tank may be waterlogged or have a faulty pressure switch. Inconsistent pressure can strain your pump and plumbing, so it’s best to have it inspected by a professional. Maintaining a stable pressure is what should well pressure be.
So, keep an eye on your gauges and remember what should well pressure be! If anything seems off, don’t hesitate to call a pro. Better safe than sorry, right? Thanks for reading, and here’s to happy, healthy wells!
