Pressure tanks play a crucial role in maintaining consistent water pressure in your home’s plumbing system. Whether you rely on a well or an on-demand water supply system, your pressure tank ensures that water flows smoothly to your faucets, showers, and appliances. However, like any other part of your plumbing system, pressure tanks can experience problems that may require repair or replacement.

One of the most common issues homeowners face is a waterlogged pressure tank. If you’re dealing with this problem, you’re not alone. Pressure tanks can become waterlogged over time due to normal wear and tear, improper maintenance, or faulty components. Fortunately, there are ways to repair a waterlogged pressure tank and restore it to its optimal functioning.

In this blog, we’ll discuss how to repair a waterlogged pressure tank, common pressure tank issues, and when to call a professional plumber. We’ll also cover preventative maintenance tips to ensure your pressure tank lasts for years to come.

Understanding the Pressure Tank

Before diving into the repair process, it’s essential to understand what a pressure tank does and how it works. A pressure tank is a critical component of a water supply system, particularly for homes using a well system. It helps regulate the water pressure and ensures a constant, steady flow of water by storing water and releasing it when needed. This system prevents the water pump from turning on and off too frequently, which could wear out the pump over time.

Pressure tanks typically consist of a metal shell containing an air bladder or diaphragm. The bladder separates the air and water inside the tank, helping to maintain pressure in the system. When you use water in your home, the water level in the tank decreases, and the pressure drops. The air bladder then pushes water back into the system to restore pressure.

What is a Waterlogged Pressure Tank?

A waterlogged pressure tank occurs when the air bladder inside the tank fills with water, preventing it from doing its job of maintaining pressure. When the bladder is compromised or fails, water takes up the entire tank, leaving no room for air. This results in low or fluctuating water pressure, which can cause issues like:

  • Fluctuating water pressure: The pressure might vary dramatically, leading to weak water flow or sudden surges.
  • Frequent cycling of the pump: The pump may cycle on and off more often than normal, which can cause excessive wear and tear on the system.
  • No water pressure: In extreme cases, a completely waterlogged tank can result in no water pressure at all.

Waterlogging is a common issue for pressure tanks, but it can often be repaired if addressed early.

How to Repair a Waterlogged Pressure Tank

If your pressure tank is waterlogged, you may be able to fix it with some simple steps. However, if you’re not comfortable performing the repairs yourself, it’s always best to contact a professional plumber who can handle the job safely and effectively.

Here’s a step-by-step guide to repairing a waterlogged pressure tank:

1. Turn Off the Power and Water Supply

Before you begin working on the pressure tank, turn off the power to the well pump or water system. This can usually be done by switching off the circuit breaker that controls the pump. Next, shut off the main water supply to prevent water from flowing into the tank while you work.

2. Check the Pressure Gauge

Inspect the pressure gauge on the pressure tank to see if the pressure is reading too low. Typically, a well-maintained system will have a reading between 40-60 psi (pounds per square inch). If the pressure is significantly lower, the tank may indeed be waterlogged.

3. Release Water from the Tank

To remove the excess water from the tank, you’ll need to drain it. Open the drain valve on the bottom of the tank, allowing the water to flow out. This will help release the water that has accumulated in the tank, allowing the bladder to refill with air.

Tip: Use a hose to direct the water to a safe area to prevent flooding around the tank. If you’re unsure where the water is draining, use a bucket to catch it.

4. Check the Air Pressure

Once the water is drained, it’s time to check the air pressure in the tank. The air pressure should be set to 2 psi below the cut-in pressure of your system. For example, if your pressure switch is set to cut in at 40 psi, the air pressure in the tank should be set to 38 psi.

To check the air pressure, use a tire pressure gauge. If the pressure is too low, you can add air using a standard air compressor.

Important: Never overinflate the air pressure, as this can cause damage to the bladder inside the tank.

5. Re-Pressurize the Tank

After adjusting the air pressure, you’ll need to turn the power back on and let the system re-pressurize. Turn on the water supply and allow the pump to fill the tank with water. Check the pressure gauge to ensure that the system is holding steady pressure.

6. Monitor the System for Issues

After completing the repair, monitor the system over the next few hours to make sure everything is functioning properly. You should notice stable water pressure without frequent cycling of the pump. If the pump continues to cycle on and off, or if you still experience fluctuating pressure, there may be an issue with the air bladder or another part of the system, and you may need professional assistance.

When to Call a Professional Plumber

While the steps above can help fix a waterlogged pressure tank in many cases, there are times when professional help is necessary. Here are a few situations where you should call a plumber:

  • The air bladder is damaged: If the air bladder is torn, cracked, or otherwise damaged, it cannot be repaired by simply draining the tank and adding air. A plumber will need to replace the bladder or, in some cases, the entire pressure tank.
  • Persistent waterlogging: If the pressure tank continues to waterlog despite regular maintenance, there could be a deeper issue with the system, such as improper tank sizing or pressure issues in your plumbing.
  • Corrosion or leaks: If you notice rust, corrosion, or leaks around the tank, it may need to be replaced. A professional plumber can assess the condition of the tank and recommend the best solution.
  • Unusual noises or malfunctions: If your water tank is making unusual sounds or you’re experiencing pressure inconsistencies that can’t be resolved through basic repairs, it’s time to call in a professional.

Preventative Maintenance Tips for Your Pressure Tank

Regular maintenance is key to preventing future waterlogging issues and ensuring the longevity of your pressure tank. Here are some preventative maintenance tips to keep your tank in top shape:

  1. Check Air Pressure Regularly: Every 6-12 months, check the air pressure in your pressure tank. Adjust as needed to maintain the correct psi.
  2. Flush the Tank Annually: Sediment can build up in the tank over time, affecting the efficiency of the bladder. Flushing the tank annually can prevent buildup and keep the tank functioning smoothly.
  3. Inspect the Tank for Leaks or Damage: Look for signs of rust, corrosion, or cracks around the tank. These can indicate issues that need immediate attention.
  4. Test the Pressure Switch: The pressure switch controls the on-and-off cycle of your pump. Testing it annually ensures that it’s working properly and prevents overpressurization or underpressurization.
  5. Install a Water Softener (If Necessary): If you live in an area with hard water, a water softener can help prevent sediment buildup in your tank, reducing the likelihood of waterlogging.

Conclusion: Keep Your Pressure Tank in Top Condition
