At Aquatek, we’ve worked with homeowners for years to solve everything from low water pressure in well systems to complete no water pressure house emergencies. One of the most common issues we see comes down to improper 40/60 pressure switch settings or an unbalanced pressure tank.

If your system isn’t dialed in correctly, you may notice inconsistent pressure, short cycling, or even long-term damage to your pump. The good news is that once you understand how your system works, you can spot problems early and know when it’s time to call in a professional.

What Is a 40/60 Pressure Switch and How Does It Work?

A 40/60 pressure switch controls when your well pump turns on and off to maintain consistent water pressure.

When pressure in your system drops to 40 PSI, the switch signals your pump to turn on. Once pressure builds to 60 PSI, the pump shuts off. This cycle keeps water flowing steadily throughout your home without overworking your system.

If your well pressure switch settings are too low, you’ll experience weak flow. If they’re too high or inconsistent, your pump may cycle too frequently, leading to premature wear.

• 40 PSI (cut-in): Pump turns on
• 60 PSI (cut-out): Pump turns off
• Balanced cycling: Prevents pump damage and ensures steady flow

When these settings are off—even slightly—it can throw off your entire system.

How Does a Pressure Tank Affect Water Pressure?

Your pressure tank stores water under pressure and reduces how often your pump needs to run.

Inside the tank is an air bladder that compresses as water fills the tank. This stored pressure allows water to flow immediately when you turn on a faucet, without the pump needing to start every time.

If your pressure tank is not properly calibrated, it can lead to:

• Short cycling (pump turning on and off too quickly)
• Inconsistent water pressure
• Reduced pump lifespan

For a 40/60 system, the tank’s air charge should typically be set to 38 PSI (2 PSI below the cut-in pressure). This ensures proper balance between air and water inside the tank.

What Causes Low Water Pressure in a Well System?

Low water pressure in a well system is usually caused by mechanical issues, incorrect settings, or buildup within your plumbing.

Common causes include:

• Clogged faucet aerators or showerheads
• Leaks in plumbing lines
• Incorrect pressure switch calibration
• Waterlogged or failing pressure tank
• Sediment buildup in pipes or fixtures

If your home suddenly has no water pressure, the issue could be more serious, such as a failed pump, electrical issue, or a tripped breaker.

How Can You Fix Low or No Water Pressure?

You can often resolve minor pressure issues with simple maintenance, but persistent problems usually require professional evaluation.

Start with these quick checks:

• Clean faucet aerators and showerheads
• Inspect visible plumbing for leaks
• Check your pressure switch for proper settings
• Verify your pressure tank air charge

If those steps don’t solve the issue, your system may need adjustment or repair. In many cases, homeowners dealing with no water pressure house situations are facing deeper mechanical issues.

Water quality can also impact your system. If buildup is affecting flow, you may benefit from reviewing options like choosing the best water softener for your home.

Why Do Incorrect Pressure Switch Settings Cause Problems?

Incorrect well pressure switch settings disrupt system balance and can damage your equipment over time.

When settings are too narrow, your pump cycles too frequently. When they’re too wide, pressure becomes inconsistent across your home.

This leads to:

• Uneven water flow
• Increased energy usage
• Premature pump wear

We often see systems where homeowners attempt DIY adjustments without recalibrating the pressure tank, which creates ongoing issues instead of fixing them.

When Should You Call a Professional?

You should call a professional when pressure issues persist after basic troubleshooting or when system components need adjustment.

Situations that require expert help include:

• Sudden loss of water pressure
• Frequent pump cycling
• Unusual noises from your tank or pump
• Inconsistent pressure throughout the home

At Aquatek, we perform full pressure system evaluations, checking your switch, tank, pump, and plumbing to identify the root cause—not just the symptom.

Serving Homes Across Our Local Service Area

We regularly help homeowners across DuBois, Brookville, Clearfield, Punxsutawney, and surrounding Pennsylvania communities address well system challenges. Local water conditions, well depth, and system age all play a role in how your 40/60 pressure switch performs, which is why localized expertise matters when diagnosing issues.
