Look for any "terms & conditions" verbiage concerning how you might be using your pool. For example salt systems invite corrosion, and this is can be a reason for a damage claim unpaid.

Warranty Void if:

"Damages caused by the utilisation of a salt water chlorination system in combination with a steel pool structure (top ledges, uprights, joiner plates, wall
channels)."
