Why Use a Well Pressure Tank?

Well Pressure Tank

Most modern, professionally installed well systems will have a pressure tank, as it is an essential part of a properly functioning system.

Regulate system pressure

Groundwater that reaches the surface through a well is naturally pressurized. However, the amount of pressure exerted through the system might not necessarily meet the needs of the entire household.

The pressure tank stores water and keeps it under pressure, and releases it on demand whenever a water fixture in the house is used.

Without sufficient pressure, water from the fixtures would trickle out slowly.

The pressure tank ensures that the system pressure is within the proper range, providing sufficient water pressure throughout the entire household.

Reduces wear on water pump

Because the pressure tank is able to store a certain amount of water under pressure which can be accessed on-demand, it eliminates the need for continuous water pump usage.

With a pressure tank, the water pump will only be turned on when the system pressure drops below the threshold level and will shut off again once the pressure reaches the threshold.

Without a pressure tank, the water pump would be turned on every time a sink, shower, or any other water fixture is accessed.

This continuous usage would cause unnecessary wear on the water pump and would certainly require more frequent maintenance.

Reserve water storage

With a large pressure tank, water can still be accessed temporarily in the event of a power outage or pump failure. The water reserved in the tank will continue to be used until it is depleted or until power is restored.

A system without a pressure tank will immediately cease to produce water as soon as the water pump shuts off.

Saves energy

With the intermittent use of the water pump due to the pressure tank reserve, electricity is used less often, and therefore energy costs are lower.

A system without a pressure tank would require consistent water pump usage.

How Does a Well Pressure Tank Work?

Well Pressure Tanks

The key concept behind any modern well system is pressure.

As the water pump forces the water upward from the well into the piping system of the home, pressure gradually builds up.

The purpose of the tank is to hold, read, regulate, and release pressure as necessary.

Types of Pressure Tanks

Larry Elterman / Youtube

One Compartment Pressure Tank - Before the invention of bladder and diaphragm pressure tanks, both water and air were stored in one stainless steel casing.

Pressure was created by compressed air, which would push down on the water. A common problem with this type of tank is that air would gradually dissolve into the water and significantly reduce water pressure, a problem known as "waterlogging".

Bladder and Diaphragm Tanks - In order to prevent the waterlogging issue, an invention was made that would separate the water from the air in the tank.

Bladder Tanks and Diaphragm Tanks are essentially identical in function and purpose, save for a slight difference in design.

Diaphragm tanks separate the air and water with a layer of rubber which rises and falls according to the pressure in the tank. Bladder tanks hold the entire volume of water in an enclosed rubber bladder which enlarges and contracts according to the pressure in the tank.

Both types of tanks are designed to separate the water from the air in order to prevent waterlogging.

Pressure Tank Mechanics

Confuciou / Wiki Commons

The following will explain how a bladder/diaphragm tank works in a well water system. For this scenario, a pressure range of 40-60 psi will be used.

  1. Starting with a full tank, the pressure gauge should read somewhere between 40-60 PSI. The water pump is off and the system is stable and idle.

  2. As soon as a water fixture in the home is used –the kitchen sink, for example– the compressed air in the tank will push against the bladder/diaphragm, forcing water out of the tank, through the plumbing system, and out of the faucet.

    Water will continue to be drained from the tank until either water usage has ceased or until the water pump turns on.

  3. As water continues to drain from the tank, the pressure will drop. When the pressure drops below the threshold of 40 PSI (also known as pump "cut-in" pressure), the pressure switch will signal the water pump to turn on.

  4. With the water pump turned on, water is being pumped from the well and into the system, gradually filling up the water tank once again.

  5. As the tank fills with water, the bladder/diaphragm expands, creating more air pressure inside the tank.

    Once the pressure in the tank meets the 60 PSI threshold (pump "cut-out" pressure), the pressure switch will signal the water pump to stop pumping, ceasing the influx of water into the tank.

  6. With the water pump off, the pressure in the tank will remain at 60PSI until more water in the house is used, draining the tank once again. Once the pressure drops to 40 PSI, the pressure switch will signal the pump to turn on once again, starting the cycle over.

Components and Consideration Factors

Pressure Tank Attachment

Air Valve - Pressure tanks will have an air valve used to release pressure and to perform maintenance testing. Typically, a pressure gauge will be attached to the air valve in order to read the air pressure from within.

Drawdown Capacity - Because of the requirement for air pressure from within, the tank is never fully occupied with water. Thus, the amount of available water will always be less than the actual size of the tank in terms of gallons.

The maximum amount of water a tank is actually able to provide is known as drawdown. Drawdown is dependent on a number of factors, including the size of the tank, the household demand for water, and the size of the pump.

Diaphragm/Bladder - Modern residential well systems should use tanks which use a diaphragm or bladder in order to reduce waterlogging. Diaphragm/Bladder material is usually made of durable, non-corrosive rubber. A pressure tank which uses a diaphragm or bladder will usually come "pre-charged", which means the air inside the tank is factory sealed and pressurized for use.

Steel Tanks vs Fiberglass Tanks

Steel - Most pressure tanks on the market are made of a high-strength steel shell with a polypropylene inner-lining. The lining is to ensure that the water is protected from making contact with the steel, which can corrode and damage the tank. Steel tanks are durable but are prone to rust.

Fiberglass - Fiberglass tanks offer an alternative to steel tanks in that they're resistant to rust and use the full drawdown capacity due to their lack of an internal diaphragm. They're also easier to install and lighter in weight but more expensive than steel tanks.

Water Pressure Tank Sizing Guide

House Diagram

Choosing the right size for a pressure tank is critical as it can greatly affect the life of the pump.

A tank which is too small for the water demand may result in pump overuse.

As a general rule, it's usually safer to err on the side of a larger tank.

While the logic behind sizing a pressure tank is fairly straightforward and can be done with a few general rules of thumb, it is best practice to consult with the pump and tank manufacturers for specifications.

Drawdown Capacity

The volume of water which the tank will hold will always be less than the actual size of the tank. This is referred to as the tank's drawdown capacity. In the process of sizing the tank, the drawdown capacity is the number that is sought after.

With the necessary drawdown capacity determined, the actual tank size can then be decided.

Flow Rate - The drawdown capacity is dependent on a variety of factors, but perhaps the most important is the pump's flow rate. At this point, the water pump has already been selected based on the household's demand for water and the well capacity.

The water pump's flow rate in GPM will be needed to determine the tank's required drawdown capacity.

For pumps with a flow rate of less than 10 GPM, the required drawdown capacity would be determined by multiplying the flow rate by 1.

For example, a pump with a flow rate of 8 GPM would require a tank drawdown capacity of 8 Gallons. For pumps with higher flow rates, the equation changes. The following equations give a general rule of thumb for determining drawdown based on the flow rate:

For flow rates between 0 and 10 GPM, multiply by 1.

For flow rates between 10 and 20 GPM,  multiply by 1.5

For flow rates larger than 20 GPM, multiply by 2.

Based on the above equations, a pump with a flow rate of 16 GPM would need a tank with a 24-gallon drawdown capacity (16 x 1.5 = 24).

Pressure Settings

With the required drawdown capacity determined, the proper tank size can be decided by consulting the manufacturer's sizing chart.

Most tank manufacturers will have a chart which lists the various tank models alongside their respective drawdown capacities. One thing to note is that there will be separate columns for each pressure setting.

For example, a system running on 40/60 pressure setting will only need to reference that portion of the chart, as a 40/60 setting will have a different drawdown capacity than a 50/70 setting. 

By referencing the required drawdown capacity within the correct pressure setting column, the exact tank model and size can be decided.

Well Pressure Tank Troubleshooting and Maintenance Guide

Pressure Tank Gauge

It is important to often check your well pressure tank to ensure that it is functioning properly. You can follow these steps to troubleshoot your tank if you encounter these issues.

Rupture of the Water Tank Bladder

A rupture of the water-containing bladder in the tank will result in a very short water draw-down cycle before the water pump runs. To determine whether there is a rupture:

  1. Check if water comes squirting out of the tank top air valve

  2. Check if the air is squirting out of plumbing fixtures

  3. Check whether you can drain water out of the tank

When this happens, you can ask your plumber to try to repair it or replace the entire water tank bladder.

Leakage of the Water Tank Bladder

If the tank’s internal bladder has a small leak, the tank air pressure will increase above the standard air charge pressure. This would lead to pump short cycling and an apparent water-logged pressure tank. To determine whether there is a leak,

  1. Check whether the water pressure tank draw-down cycle is shorter than normal

  2. Measure the water tank pressure at the air gauge and check whether it has crept up above normal levels

  3. Turn off the pump and drain the water pressure from the system, then check whether the water pressure tank is abnormally heavy.

When this happens, you can consult a plumber to investigate and repair the leakage.

Waterlogged Issues with Bladder Pressure Tank – Pulsing Water

Waterlogging occurs when the air space in the internal bladder fills up with water. You should replace waterlogged tanks as it is often the most cost-efficient. To determine whether your tank is waterlogged:

  1. Gently tip the tank and notice the weight

  2. Check whether the pump motorcycles on and off rapidly

  3. Tap on the outside of the tank and listen. The sound will be different from that of a proper air-water balanced tank

  4. Depress the central pin of the air-charging valve, and check whether water escapes through the charging valve instead of air

  5. Check whether stale, rusty water appears at the tap which is typically caused by corrosion inside the tank

If Your Tank is Waterlogged:

  • For bladder tanks, drain the water pressure by turning off the power and opening the drain faucet of the tank.

    Check the pressure using a tire gauge once the water has been drained and adjust to approximately 30 psi if possible, then re-activate the system and flush until the water is clear.

  • For air-over-water tanks, you can air charge your tank by consulting your service technicians

Well Pressure Tank FAQs

How Do I Check the Pressure in the Tank?

A pressure check should be done at least twice a year but ideally every couple of months. To do so, turn the pump breaker off and drain all the water from the tank by opening a faucet in the system. Remove the air valve cap and check the pressure with a pressure gauge.

How Long Can a Pressure Tank Last?

A pressure tank which is properly maintained and serviced can last between 10-15 years depending on the quality of the build.

Can a Pressure Tank Be Installed Outside?

It is NOT recommended that a tank be installed outdoors where temperatures can drop below freezing or exceed 100 degrees Fahrenheit. Extreme temperatures can damage or distort some of the components. It is always best to install the pressure tank indoors, preferably in the basement and closest to the waterline.

Can a Pressure Tank Be Too Large?

The larger the pressure tank, the more beneficial for the entire system due to less frequent pump cycles and larger storage volume. In theory, there is no limit to the size a pressure tank can be provided the physical space is available to accommodate it.

Can Multiple Tanks Be Linked Together?

Yes, linking multiple tanks together via T-fittings can increase drawdown capacity and reap the benefits of having a larger tank. In some cases, it makes more financial sense to purchase an additional tank instead of replacing an old tank with a larger one.


If the pump is considered the heart of the well system, the pressure tank might be considered the lung. By regulating the air pressure through the expansion and contraction of the diaphragm, the pressure tank is responsible for keeping the pressure of the entire system within functional range. Without a pressure tank, the well pump would certainly be overworked and may malfunction prematurely. Selecting the right brand and size of pressure tank for a well system is one of the crucial decisions and well owner needs to make.
