A pressure tank in a private water system stores water and serves as a water supply reserve. It is made of metal, steel, or fiberglass and varies in size. With technological advancement, we install a new pump with a pressure tank. A pressure tank prevents your pump from fluctuating on and off when your household needs water. You can contact an expert for water tank products in Carson City NV.

However, preventative maintenance is necessary to ensure the system runs smoothly. Pressure tanks have a limited time span. Quality and well-maintained pressure tanks can last 10-12 years, while cheap quality tanks last only five (5) years or less.

The Following Factors Determine the Quality of a Pressure Tank:

    • Quality of the system

    • Size of the pressure tank

    • The setting of the whole system

Factors Affecting the Longevity of Your Pressure Tank

1. Corrosion Development

Corrosion is one of the common problems occurring in a pressure tank. The corrosion rate will be faster if the pressure tank contains corrosive chemicals. However, it also depends on chemical concentration and temperature. If the pressure tank has sulfuric acid, corrosion may occur faster. The corrosion development can cause a pinhole failure.

2. Faulty Pressure Vessel Materials

Independent fabricators are used to fabricate pressure tanks. Low-priced or low-quality fabrication can develop faults. Reputable fabricators check the material certificates and verify the installation of pressure vessel materials, ensuring quality results. 

Other factors like unexpected operating conditions can cause a pressure tank failure. Consulting with an expert can help identify the problem. 

Signs of a Pressure Tank Failure

    • Pressure switches on and off 

    • Low water pressure

    • Visible corrosion on the tank 

    • Excessive air in the plumbing

    • Unstable water pressure

    • Pumps running less than 30 seconds

    • Pressure tank leaks

How Often Should You Replace Your Pressure Tank?

While the average lifespan of a pressure tank is 10-12 years, well-maintained pressure tanks can also last for 15 years. If your pressure tank produces clean water and the size of your pressure tank is appropriate, it can last for 15 years—however, brand and quality matter. You must ensure the upkeep of your pressure tank and schedule an inspection for potential repairs. 

Consider the Following While Choosing a Pressure Tank

    • Tank material selection 

    • Pressure tank design 

    • Industry standards for pressure tanks

How to Extend the Lifespan of Your Pressure Tank?

    • Install constant pressure valve

    • Add air volume control system

    • Adjust or replace the pressure gauge

    • Replace the clogged water filter

    • Add a new filtration system


Pressure tanks can last for decades with quality maintenance, including inspection and potential repairs. You can try DIY repairs, but ensure to do it right because faulty repairs do more harm.
