How Does A Well Water Pressure Tank Work
The primary purpose of installing a water tank with a well is to store water to supply water at constant pressure in your entire home. Water from the well enters the pressure tank and is then distributed to your homes plumbing system.
Three types of pressure tanks are used for storing water in a well water system.
- Air-over-water tanks
Lets learn about each types functionality to understand how they work!
Air-Over-Water Tank: This type of tank works by maintaining a layer of air over water. The pressurized air over the water pushes down on the water to create the pressure needed to supply water to your home.
Air-over-water tanks were frequently used a few years ago, but their use is rapidly decreasing. These tanks appear larger than others but have a small capacity. The small capacity causes the pump to cycle on and off repeatedly and leads to premature failure.
Diaphragm Tanks: These tanks have two chambers inside a single tank. One chamber is dedicated to water, and the other is to air a rubber diaphragm separates both chambers. The rubber diaphragm is permanently attached to the tanks inside, rising or falling with the water level inside the chamber.
When the water enters the lower chamber, it pushes the diaphragm up. This triggers a switch that turns off the pump.
A couple of issues in this tank start showing up after a couple of years. The diaphragm gets loose or folds over itself. The only solution to both problems is replacing the water tank.

Tips For Testing & Repairing A Traditional Hydro
Type 2 tanks, described by WellMate as hydro pneumatic water tanks, do not incorporate an internal bladder but rather an air volume control valve that replaces air into the tank as needed. These tanks will perform better than older steel water pressure tanks because we dont face the concern of rust perforation of the tank.
If the air volume control fails, the tank will act much like a type 2 tank
See TANK TYPES: WATER, OIL, EXPANSION, ALL and scroll down to the description of older steel water tanks. In this case you may need to replace the AVC.
Draining and adding air to an AVC type tank with a failed AVC also MIGHT work to improve performance for a while but you need to replace the AVC.

How To Fill Or Adjust Well Water Pressure Tank
The well water tank has water at the bottom and air at the top. This setup helps maintain constant pressure in your home.
You will need a pressure gauge and an air compressor to fill the water pressure tank with air. Find out the air valve on your tank. It is usually located on top of the valve. The air pressure inside the tank must be 2-3 PSI less than the cut-on pressure.
Adjust the air pressure as per the reading you get on the gauge. You should use a high-quality digital gauge so you get accurate measurements.
How Do You Know If A Pressure Tank Is Bad List Of Symptoms
There are a few clear signs that indicate if a pressure tank has gone bad. If you notice one or more of these in your home, it might be a good time to get your pressure tank checked out:
- High fluctuation of water pressure from different water sources in your house
- Abnormal noises like clicking sounds coming from the water tank
- Spitting and spraying faucets or shower heads
- Extremely hot shower water
- Flickering lights when water is being used
- Discolored water coming from your faucets
Certain tanks can also experience waterlogging, which is the term for when the entire tank is filled with water. This will prevent the tank from functioning properly, and will likely require you to get it replaced.
It is suggested that homeowners check their pressure tanks every so often to notice any visible signs of malfunctioning or deterioration. A few things to look for are leaks on the outside of the tank which can be detected by seeing a trail of water running down the side. You can also look for wet spots or puddles of water underneath the base of the tank.
Another indicator that your tank may need to be replaced is if you see spots of rust or corrosion on the seams of the tank. While most signs of needing a pressure tank replacement can be easily observed, it is recommended to regularly inspect your unit to spot them early on.

How To Tell If Your Well Water Pressure Tank Is Bad
A bad well water pressure tank can create a few problems for your household. Hence, it needs to be replaced as soon as possible. The following signs indicate a well water pressure tank replacement.
Fluctuation in water pressure: There can be several reasons behind water pressure fluctuation in your home. However, it doesnt necessarily mean that fluctuation is due to a bad pump, but it is a reaso0n enough to get your pump inspected to avoid any further damage.
Noisy pressure tank: The pressure tank sends signals to the water pump to turn off or on. You will listen to continuous clicking sounds if the pump has gone bad. Any problems in the air-water system inside the pump warrant an instant pressure tank replacement.
Spitting faucets: If all the faucets in your home are spitting or coughing, it could happen due to a faulty water tank.
High electric bills: A faulty water tank not only impacts your homes flow rate but also skyrockets your monthly electricity bills. This hike is because the pump stays on for more time due to a faulty water tank.
Damaged well pump: A well water pump can last 10-15 years without any issues. If the pump starts creating a problem unexpectedly, it is most probably due to a faulty well tank.

What Size Well Water Pressure Tank Do I Need
Installing the right-size pressure tank with your water well is critical to maximizing the systems efficiency and extending the pumps motor life. A rightly sized pump reduces the risk of premature pump failure by extending the time between the cycles.
A large tank is a better option considering these facts, but some constraints like budget and installation space may stop you from buying a big tank. The rational approach here is to size the tank accurately so you dont have to face issues later.
Before we explain how to size the well water pressure tank correctly, it is important to bust a common myth about pressure water tanks. Many people believe that the well waters stated size is the tanks actual drawdown . This isnt true. The actual drawdown capacity is around 40% percent of the stated capacity.
Before calculating the pressure tank size, you need to know about the following 3 things.
Flow Rate: The flow rate is how many gallons your pump produces in one second.
Cut-in/Cut-out PSI: These are the pressure settings on your pump. They are usually given in 20/40, 30/50, and 40/60 settings.
Minimum Runtime : This is the minimum time a pump runs between the cycles.
An easy way to determine your tanks drawdown capacity is given below
Flow Rate x Runtime = Tank Drawdown Capacity
Please note that pumps with a flow rate or capacity up to 10 gallons a minute should have a tank with a minimum one-gallon drawdown capacity for each gallon per minute of the pump.
When Should I Replace My Pressure Tank
A well-maintained water tank can last up to 25 years and in some cases more. Water tanks usually come with a five-year warranty to make sure it does not break down or malfunction before it is supposed to.
The lifespan of a pressure tank can also be affected by the quality of water that is being pumped from your homes well source. If the water is sandy, rocky, or commonly has sediment in it, then that can erode the pressure tank over time and cause a hole to form. If your well pumps coarse water, then you are likely to need a pressure tank replacement sooner than you might think.
Finding an issue with your pressure tank does not necessarily mean you need to replace it. Sometimes there is a problem that can be fixed without installing a new tank.
Some of these solutions include:
- Installing a new filtration system
- Replacing your tanks water filter
- Adding a constant pressure valve
- Installing an air volume control system
- Toying with or replacing the pressure gauge
There are also a lot of tips on maintaining your well which can help you increase the longevity of your water tank. These include:
- Keeping fertilizers, pesticides, paints, oils, and all products that contain toxic chemicals away from your well pump
- Keep the area around your well clean and dont let leaves or debris pile up around it
- Be careful around the casing of your well
- Regularly check the well cover or well cap on top of the casing of your well

What Is The Purpose Of A Bladder Tank
The purpose of a bladder tank is to efficiently store and create pressurized water for houses and appliances that require power or water as a resource.
The bladder tank manages to do this by utilizing space inside the tank to create pressurized air. That pressurized air then pushes water at 20-40 psi, depending on the configuration and intended use.
Galvanized pressure tanks, while bigger, are less efficient at creating pressure because of the volume of water it takes to generate compressed air inside the tank.
The more water a pressure tank loses, the less powerful the air pressure is. The air pressure in a bladder pressure tank continues to thrive because of the vacuum created by the tank and balloon.
Another essential thing to note is the compact nature of the bladder pressure tank. Its able to serve multiple purposes because of its size.
Smaller homes with less space will find it challenging to fit an entire galvanized pressure tank casually in their home.
Common Signs Of A Well Water Tank Problem
When a well water tank is leaking, its bladder has failed, or it has become waterlogged, you may notice several symptoms, including:
- Reduced water pressure, especially at fixtures on the second floor
- Unstable water pressure as the pump cycles on and off
- A pump that runs less than 30 seconds to pressurize the tank
- A pump that cycles on and off frequently or remains running
- Water leaks at the pressure tank
- Visible corrosion on the exterior of the tank
- Excessive air in plumbing system as faucets and fixtures are used
- Low pressure at the tanks pressure gauge
If you notice any of these problems, the well water tank may need to be replaced. Have a professional inspect the system as soon as possible to avoid causing damage to the pump or premature failure. Well pumps can be expensive to replace, especially submersible models, which require significant labor to extract from the well.

Tips For Testing & Repairing A Captive Air Water Tank Bladder
Try this: if you have this type of tank, remove the valve step cap covering the bladder inflator valve located on the top of the tank. Using a small implement, MOMENTARILY depress the valve pin in the center of the valve stem down to see if air or water comes out. If water comes out of this valve the air bladder has burst.
But the bladder could be burst but blocking the valve in which case nothing will happen. If air comes out of this valve the the tank bladder contains air and may not have burst.
If air comes out of the valve, use an accurate tire gauge to check the air pressure at the valve.
If the air pressure is 4 psi below the well pump cut-in pressure then the air bladder is probably fine. If the air pressure is less than that figure, using a bicycle pump, just add a little air to the bladder until it is set to the proper number 4 psi below the pump cut-in pressure.
Draining the water tank itself and adding air to a bladder type tank itself through the bladder valve at the tank top of a tank with a failed bladder MIGHT work to improve performance for a while but you need to replace the bladder.
A guide to replacing the air bladder in the WellMate captive air tank is provided by the company at http://www.wellmate.com/pdf/Residential_AirCell_Replace_Instructions.pdf
The air bladder in the WellMate type water tank is to be inflated to 4 psi below the well pumps cut-in pressure.
