Water Pressure Tank Problems & Troubleshooting

A water pressure tank stores water for your household and protects the well pump from turning on every time you open a faucet. A water pressure tank usually lasts for 5-7 years, but it can fail early for various reasons.

If the water pressure tank in your home goes bad or starts creating problems, you must know how to troubleshoot it to ensure a constant supply of water to your home. Moreover, you can save a lot of money by troubleshooting a water pressure tank.

In this article, we will discuss the common water pressure tank problems and how you can troubleshoot them. This article will also focus on how to fix a waterlogged well water pressure tank?

Water Pressure Tank Problems & Troubleshooting

Loud Noises: If you hear loud bangs in your plumbing when you open a faucet, it can happen due to a bad water tank. The loud bang, also known as water hammer, happens when the water flow suddenly stops in the pipes. This sudden stop causes water pipes to hit each other.

These loud noises or water hammer occurs when your pressure tank fails to maintain constant water pressure. The water pressure inside the tank can get disturbed due to many reasons. For example, air pressure drop or increase, wrong pressure settings on the pump, or diaphragm damage.

Worn Out Well Pumps: The pump in your water well pumps water from the well, which is stored in the pressure tank. The water tank sends a signal to the well pump to turn on/off depending on the water inside.

If these signals are incorrect, the well pump will turn on/off unnecessarily and cause problems.

The best way to deal with this problem is to measure the pressure on the water tank. You will also need to check the air pressure to see if there is any problem. The air pressure must be 2-3 PSI less than the cut-on pressure of your well pump. If the cut-on pressure on your well pump is 30 PSI, the air pressure in the pressure tank must be 27-28 PSI.

High Electricity Bills: Your well contractor will provide you with an estimated cost of running a water well. This cost is based on various factors like your household size, how much water you use, and how much time the pump stays on.

If you notice an increase in your electricity bill, don’t forget to check the water pressure tank and pump. These problems can sometimes be fixed by changing the settings on your well pump.

Low Water Pressure or No Water: If the pump is running and you notice no water or low pressure in the faucets, it is likely due to a faulty water tank. Low water pressure can indicate a failing pump, closed valve, leaking pipe, or leaking pressure tank.

You need to inspect all the components in your well water system to see the problem and how you can fix it.

Change in Water Quality: Issues with your pressure tank can alter water quality and color. If contaminants get lodged at the bottom of the tank, they will mix with water and come through faucets. This problem can also slow down the flow rate.

You won’t notice the change in water quality if you have a water filter installed after the water leaves the tank. To solve this problem, you will need to clean the tank. To do this, turn off the water pump and open the drain valve on the pressure tank by connecting a garden hose to it and emptying it into a clear container.

Notice the collected water for any sediment or suspended particles. If the water has sediment, turn on the pump and gather a few liters of water in it. Empty water again and keep repeating this step until the water comes out clean.

How to Fix a Waterlogged Well Water Pressure Tank

A well water pressure tank utilizes air to function properly. The air pushes the water at the bottom and exerts pressure over the water to maintain a constant pressure so that when you open the tap, water comes out at a constant flow rate.

The pressure tank maintains a constant ratio of air to water in it. If this ratio is disturbed in such a way that there is more water in the tank than air, it is said to be waterlogged.

The most common problem you will face with a water pressure tank is waterlogging. Many homeowners report this problem. A waterlogged water tank can sometimes be fixed but may need replacement if the problem persists.

Sings of a Waterlogged Tank

  • The water pump turns on/off continuously
  • Water coughing or pulsating at taps
  • A high percentage of coliform bacteria in water samples
  • Odors in water

How to fix a Waterlogged Bladder Tank?

A well water pressure tank with a bladder or a diaphragm cannot be fixed if waterlogged. Some water tanks are built in a way that allows you to replace the bladder, but the majority of the models don’t. However, it is still worth a try because these things don’t come cheap, and one should fix them before replacing them.

Let’s see how you can fix a bladder tank.

  • Turn off the power to your well pump before you begin troubleshooting.
  • Bypass the water filter system in your home.
  • Open the drain valve on the tank and drain the water in the tank.
  • Connect a pressure gauge to the pressure valve at the top of the tank and note down the pressure. If the pressure gauges 27-28 PSI, the pressure system in the tank is all right.

the pressure system in the tank is all right

  • Adjust air pressure using an air compressor to reach the desired pressure.
  • Power the well pump and check the tank to see if the problem has been fixed.

How to fix a Waterlogged Air over Water Tank?

How to fix a Waterlogged Air over Water Tank

Air-over-water pressure tanks don’t need a replacement if they are waterlogged. A diaphragm or a bladder does not separate the air and water. It is based on the principle that air is lighter than water and stays at top. However, the air and water in these tanks can mix and create waterlogging.

Here is how you can fix it.

  • Turn off the power to the well pump and empty the pressure tank.
  • Connect a pressure gauge at the air valve at the top and see the reading. It must be 2-3 PSI less than the pressure settings.
  • Adjust the air using an air compressor.
  • Turn on the power and test the system.
  • Replace the tank if needed.

Final Words  

You cannot always fix a waterlogged pressure tank. The permanent solution to this problem is to replace the tank; otherwise, it can damage more costly components in your well, like the pressure pump.
