Troubleshooting And Fixing Your Well's Pressure Tank

Posted on

If you turned on the water in your home today only to discover that you have no water pressure, then your well's pressure tank may not be functioning correctly. While pressure tanks are wonderful for increasing your home's water pressure, they come with a lot of very common problems. Learning how to troubleshoot and fix these problems can save you a lot of time and frustration.

Follow these simple steps to get the water flowing from your well to your house again:

Step 1: Visually Inspect Your Tank

The first step in fixing your home's water pressure is to visually inspect your pressure tank for leaking water. Inside of the tank's cylinder is a rubber bladder that is surrounded with pressurized air. The rubber bladder is often a point of failure due to its constant contact with pressure, water, and air.

If there is water shooting out of the air valve on your tank, then the internal rubber bladder has likely ruptured. The air valve is located on the half of the pressure tank that contains the air, and there should not be any visible water in that area.

There is no way to fix a ruptured bladder since pressure tanks are manufactured as sealed vessels. If water is coming out of the air valve, then you need to replace the pressure tank.

However, if the water is coming out of the base around the air valve where it enters the tank, then you can replace the air valve itself. You can purchase a replacement at your local plumbing supply store. The old valve can easily be removed with a pair of pliers and a new one screwed into place.

Step 2: Gently Rock the Tank Back and Forth

The pressure tank should contain both water and air. The water makes the pressure tank have some weight to it. If you gently move the tank around and it is very light, then there is no water inside the tank. This is a sign of rubber bladder failure and requires replacement of the pressure tank.

If the tank is very heavy, then it is probably waterlogged. A waterlogged tank has too much water in the bladder, which prevents air from entering the cylinder and pressurizing it.

To fix a waterlogged tank, add air to the tank through the air valve using an air compressor. Consult your tank's owner's guide to determine what the pressure setting should be.


If you were unable to fix your home's water pressure issue or are unable to determine the problem using the steps listed above, then you should contact a licensed plumbing contractor from a company like Wallace Plumbing, Inc.
