We sell Swimline liners exclusively because they are great quality, made in the USA and they stand behind their products.
Swimline warranties their pool liners for manufacturing defects. The most common manufacturing defect found in pool liners is an open seam. An open seam would be a very large opening in one of the heat sealed seams and the pool would empty very quickly.
The sand base underneath your pool liner is a very important step of the installation process. You must avoid air pockets during the liner installation.
A 3″ thick bed of sand across the entire inside of the pool (wall-to-wall) is required when installing a base underneath a pool liner. Wet the sand and tamp to form a firm, level base underneath your pool liner also. You must build up an additional 4″ of sand on an angle against the pool wall creating a 7″ cove.
Failing to install a proper cove for the liner will lead to the liner tearing at the seam. A tear at the seam is not the same as an open seam as you can see in the example below. There cannot be any air space underneath the liner. The liner is not intended to support the weight of the water.
Small holes are not defects and can be patched very easily with an underwater patch kit.
- During the installation process your liner may inadvertently get caught on the metal top joiner plate or sharp objects on the ground such as a branch or rock.
- dropped hardware (screws)
- dropped tools (screwdrivers, drills)
