Can Expansion Tank Be Reused

Reusing an expansion tank. There is no reason that you can’t use your tank if it is still holding pressure. You can check your tank with a tire gage if it’s equal to your incomming water pressure.

Water expands as it heats up, and without an expansion tank attached to the water heater, a closed plumbing system can experience damage from this thermal expansion. For example, when water is heated from the temperature of 50 to 120 degrees Fahrenheit, the volume increases by approximately 2%.

An expansion tank is most critical in closed plumbing systems, where some form of pressure-limiting valve or back-flow valve prevents the expanding water from backing up into the municipal water main.

As long as you have a place for an expansion tank on top of your water heater they are easy to install. Even if an expansion tank is not required in your area it can be a good idea to install one to prevent damage from thermal expansion.

How often should expansion tank be replaced?

But expansion tanks can wear out. The average life of your tank can be anywhere between five and 10 years. You can extend the life of your expansion tank by making sure that your home’s water pressure matches the air pressure in your expansion tank.

Can you empty an expansion tank?

Turn off the boiler and close the water supply valve. Allow the tank to cool if necessary. Connect a hose to the purge valve on the expansion tank or place a bucket beneath the tank. Open the purge valve and allow the tank to drain completely.

What causes an expansion tank to fail?

Some tanks fail when a leak develops in the diaphragm. This usually causes the tank to fill with fluid and become “water logged.” You can check for this by pressing in the stem of the Schrader valve. If a stream of liquid comes out the tank is toast.

Can you repair an expansion tank?

The only way to fix this type of leak is by opening the pipe joints and dry any water around the joints. With a cleaning agent and a scratcher pad, preferably plastic, carefully clean the threads on the pipe and joints. Cover the threads of the pipe with plumber’s putty and screw into the joint.

How do you know when an expansion tank is bad?

If your Thermal Expansion Tank is hanging from a pipe, you would push the Schrader Valve (air valve), located on the bottom of the tank, if the air is released then the tank is working properly. If nothing or water comes out your tank is bad and needs to be replaced.

What happens when expansion tank fails?

How often do expansion tanks need to be replaced?

But expansion tanks can wear out. The average life of your tank can be anywhere between five and 10 years. You can extend the life of your expansion tank by making sure that your home’s water pressure matches the air pressure in your expansion tank.

Does expansion tank affect water pressure?

When the system’s water is heated and expands into the tank, the diaphragm deforms and moves toward the captive air chamber. The air pressure in the tank increases and so does the water pressure in the system.

Can thermal expansion tank cause low water pressure?

Though usually not a problem, thermal expansion can lead to high water pressure and cause expensive problems. The main reason to have an expansion tank in a domestic water system is to prevent the damage from high water pressure, defined as anything over 80 psi.

How do you know if your expansion tank is bad?

If your Thermal Expansion Tank is hanging from a pipe, you would push the Schrader Valve (air valve), located on the bottom of the tank, if the air is released then the tank is working properly. If nothing or water comes out your tank is bad and needs to be replaced.

What PSI should my expansion tank be?

Expansion tanks are pre-charged with a 40 PSI air charge. If the inlet water pressure is higher than 40 PSI,the expansion tank’s air pressure must be adjusted to match that pressure but must not be higher than 80 PSI.

How do I increase water pressure in my expansion tank?

Expansion tanks are limited to a working pressure of 150 psi and up to 200 degrees F. Therefore, due to fluctuating city water pressure, you should install a water-pressure-reducing valve where the water enters the house. This will provide a steady manageable pressure to the entire water distribution system.
