Warranty

Warranty: 15 years prorated

Blue Wave warrants this liner for 15 seasons against seam defects and defects in workmanship. A replacement in year 1 is free; after that the warranty is prorated, so the owner pays part of the replacement cost.

Not covered: tears or punctures from handling, shrinkage if the pool is drained, labor, water and chemicals. A 6-in cove must be installed around the inside of the wall.
