Water storage tank liners can last for years, especially with today’s technological advancements and quality water treatment. In fact, an underground tank can last 20 years or more with the right construction, installation, soil conditions, and maintenance. But even the best and most well-kept water storage tank liners don’t last forever.

It’s important to keep an eye on your liner to ensure water storage stays clean and uncontaminated. But how do you know when it’s time to replace your water storage tank liners? Here are some of the most common signs it’s time to replace your tank liner.

It’s been nearly five years

Water storage tanks can last a few decades in the right environment and with proper maintenance. But the liners that keep those tanks fresh and in shape don’t have the same lifespan.

Typically, your water storage tank liners will last anywhere between three to five years before they need to be replaced. This helps to ensure the water inside the tank remains uncontaminated and properly secured. If it’s been about five years since you first installed your water tank liner, now is certainly the best time to replace your liner.

There are cracks and rust in your storage tank

Your storage tank liner is what helps to protect the integrity of your storage tank and keep rust at bay. If you notice cracks or rust during the inspection of your tank, it could be a sign that the liner has been compromised and isn’t able to properly do its job.

Depending on the age of your storage tank, it may be in your best interest to replace not only the liner but also the tank itself. This is because corrosion only gets more persistent over time and, even with a great storage tank liner, the risk of water contamination is there.

The storage tank fails water quality tests

If your water quality isn’t up to standard, it could be a sign that the water tank liner has been compromised. Compromised tank liners can cause water storage tanks to rust and introduce corrosive chemicals into the stored water.
