Swimming pools blog

We have a small (12.5 foot diameter) Esther Williams above ground pool. I
installed iit n the spring of 1990. How long should the liner last? I don’t
want it to totally fail during the winter, or even during the summer so that we
lose all the water and damage the rest of the pool. Is that something that
should be replaced at a certain time interval, or only when it shows signs of
failing?
Also, it was such a pain to install the pool, I don’t want to go through that
again. I assume I can find someone to replace it.
