Hello. We recently had an issue with our inground pool that was installed about 6 months ago. The installer puller the liner off to fix some problems and suspected a small leak.
The galvanized steel walls have white stains on them after less than 6 months of use. The stains are thicker at the bottom than the top of the wall. It is a vinyl liner, salt water pool.
Nothing was mentioned at the time and now I wonder if the white substance might be salt?
I have a friend who had to replace their liner under warranty after 2 years due to the seam coming apart. They too have a salt water pool but their walls didn't have any staining -the wall looked just like they did on install.
See attached pic. Would appreciate any comments.
