Pool Liner Seams
Almost every pool liner warranty in the industry covers the welded seams only and nothing else. The seams, of course, are very important but if they hold for a week, they will most likely hold for seven years. If there is going to be a problem that is covered by your warranty, it will be evident soon after the liner is installed. It is very rare for a seam to fail after the first six months.
What is not covered are all the other things that may happen to your liner such as material defects, print fading, irregularities in printing, damage from pool chemicals, wind and ice damage, rips, tears or holes that can be snagged or punched in the liner.
Even if you do have a legitimate split seam warranty issue, your warranty does not cover installation, freight or the cost of water and chemicals.
Like Dad always said, warranties are designed to limit the manufacturer’s liability, not to benefit the consumer. Pool liner warranties are not any different.
Four years ago, we wrote a post about being able to see liner seams and you can click here to see what we said back then.
Over the past four years, every supplier in the industry has worked to further minimize the appearance of their seams. Some have made adjustments to the traditional welding methods and others have adopted new techniques.
No matter which process is used, every liner has the same number of seams and every seam is visible to some degree. Even those being promoted as “invisible” become noticeable when the pool is illuminated at night or when debris accumulates against the seams.
Our best advice, don’t make your decision based on a welding technology. It’s just not that important. Instead, pick a pattern you love and a local contractor you can trust. Click here to read what’s really important when replacing your pool liner, everything else can just be a distraction.
We often hear pool owners question whether they should be able to see the seams in their liner.
The answer is yes. Every liner has seams, at least every six feet, and they are more visible on some patterns than on others. In the old days, when all patterns were on blue base film, you could not really see the seams since there was less ink coverage. Today, when most all patterns are on white base film, the seams are more visible, but the less ink there is, the less noticeable they are.
We advise that you wait until the pool is filled before you worry about the seams. While they are always there, they are much less noticeable under three feet of water.
The liner pictured below (pattern: Robertson) is a good example of visible liner seams on a properly manufactured liner. The seams on the floor are barely visible. The vertical seam is razor thin, perfectly straight and the tile is matched almost perfectly at the top.
Bottom of pool (below):
Pictured below is Morrison, one of our most popular patterns. If you look closely, you can see two liner seams in the shallow end of the pool. The Morrison pattern has one of the most visible liner seams out of all of our patterns. That being said, you will notice that the seams are barely visible, especially if standing 10 feet away and if the pool is filled with water.
In the picture below, you can see a seam across the bottom of an unfilled pool (pattern: McDowell).
Below, we present you with the McDowell pattern again in a pool completely filled with water. From this viewpoint, it is impossible to notice any liner seams.
Pictured below are two more examples of highly visible liner seams on properly installed pool liners.
