Fill the tank with 25 psi of air and then turn on the pump to fill the tank with water. Open the shut off valve Although bladder-type pressure tanks cannot be air charged when waterlogged, the pressure in the tanks will drop with time (just like your car tires) and will need to be recharged.
Are bladder and diaphragm pressure tanks waterlogged?
With bladder and diaphragm pressure tanks, there is a clear barrier between the water and the air. As a result, the tanks will hardly ever be waterlogged unless there the bladder or diaphragm has ruptured, in which case the tank would need to be replaced.

Waterlogged bladder pressure tanks contribute to the following problems: The pump motor cycles too often. Frequent cycling can shorten the lifespan of a pump. Because waterlogged tanks can contain stagnant water, there can be unsatisfactory coliform samples or taste and odor complaints.
Can you add air to a pressure tank with water in it?
A bladderless water pressure tank doesn't have a balloon-like fixture and valve, but you can add air to the tank by completely draining it first via the spigot valve located at the bottom. Use a garden hose to empty out the tank, and once it has no more content, it will be filled with air.

How do you put air in a bladder tank?
A simple method for recharging the air in a water pressure tank is to turn off the pump, attach a garden hose to the tank drain, open the hose, drain the tank completely, and then let the pump re-fill the tank. Opening a nearby faucet or valve will speed the drain process and may help let air into the water tank.
How much air pressure should be in a bladder tank?
The pressure in the pressure tank should be 2 psi less than the cut-in pressure for the pump. For example, if the pump cut-in pressure is 30 psi, the tank bladder pressure should be 28 psi.
What PSI should a water pressure tank be at?
Most well tanks come set at 30/50. The cut-on pressure for the well pump is 30 psi, so the pressure of the tank should have a pressure of 28 psi. If your well tank is on a 40/60 pressure switch, your pressure setting should be 38 psi.

How often should pressure tanks be replaced?
First, the quality of the pressure tank itself. Cheaper pressure tanks will last 5 years, while high quality pressure tanks could last up to 30 years. If the water is clean and the tank is properly sized it should be lasting an average of 15 years.
How much does a bladder tank cost?
Because of their slight downgrade in performance, expect to pay around $150 to $400 for a bladder well pressure tank. Like diaphragm pressure tanks, bladder pressure tanks can reach upwards of $1,500 for larger sizes.
In This Article
To work properly, your well water pressure tank requires air space. Some tanks achieve this through an air bladder or diaphragm. Others count on the fact that air is lighter than water to keep a natural air cushion on top of the water in the tank.
Signs of a Waterlogged Tank
There's nothing subtle about a waterlogged tank, and you're likely to notice several symptoms if you have a problem. One is the constant ticking of your water pump turning on and off repeatedly, which is a problem called short cycling.
How to Fix a Bladder Tank
Although there are exceptions to every rule, most well water pressure tanks with bladders and diaphragms can't be fixed and need to be replaced. Some tanks allow you access to these parts so you can change them, but most do not.
How to Fix an Air Over Water Tank
You may have better luck when it comes to fixing an air over water tank. There are no moving parts here, so there is less that can break. Because the air and water in these tanks aren't separated, the air sometimes dissolves into the water. Adding more air is sometimes all it takes to get you up and running again.
What happens if your water tank bursts?

What happens if a pressure tank is waterlogged?
A waterlogged pressure tank can make your pump run constantly, leading to motor burn-out. If you’re dealing with a waterlogged tank, it’s essential to fix it ASAP. Typically, draining the tank and adjusting the settings can resolve the issue.
What happens if you replace a waterlogged tank?
If you only replace the pump, you’ll still have a waterlogged tank that will likely burn out the new pump.
How does a pressure tank work?
Diaphragm pressure tanks feature one chamber for air and a separate one for water. A rubber diaphragm attaches to the tank’s side, separating the air and water. The diaphragm rises when the pump pushes water into the tank. Once the diaphragm reaches the air chamber, it triggers a sensor that turns off the pump.
What is a galvanized pressure tank?
Galvanized pressure tanks are one of three types of tanks used with well water systems. You’re more likely to find these steel tanks in homes built before the 1970s. Nowadays, newer tank models and designs have made galvanized versions less popular. People also refer to these tanks as air-over-water tanks.
Why is my well water tank waterlogged?
However, when the ratio of air to water in the tank is off, you end up with a waterlogged tank. Typically, this is because there’s too much water in relation to the air in the tank. A waterlogged pressure tank can make your pump run ...
What happens if the diaphragm of a water pump is loose?
If the diaphragm comes loose, water can get into the air chamber. This causes your water pressure to drop significantly, and you would need a new tank. In some cases, the diaphragm can fold on itself, sending the pump incorrect readings, leading to motor burn-out.
Why is my water pressure wonky?
When the water pressure is wonky, your system can’t maintain the proper flow rate for water treatment devices. Therefore, your water quality suffers.
How to drain water pressure from a tank?
Drain the water pressure by turning off the electric to the pump and opening the drain faucet on the tank. Any filtration equipment (softener, iron filter, reverse osmosis system, other) should be by-passed or turned off, as draining the tank may cause sediment in the pipes or tank to be disturbed.
How to stop water from leaking in laundry tub?

What causes a waterlogged well pump?
A waterlogged pressure tank is caused by the confined space within the tank having an improper ratio of water to air (too much water, not enough air). Given the physical characteristics of water (incompressible), this condition causes the pressure to fluctuate rapidly and the well pump to go on and off too much.
Can you put a filtration tank back in service?
If the air can be adjusted, the system should be re-activated and flushed until the water is clear. Once clear, all filtration equipment can be put back "in service". These type of tanks do not have a “permanent” air charge, and many need to have air added on a routine basis.
