How long should a vinyl pool liner last? The quick answer is 10 to 15 years. However, some liners will last as little as 3 years and others will last as long as 20 years. There are many factors associated with pool liner longevity. I will cover five of these factors in the remainder of this article.
Pool Liner Stains
Stains on pool liners can be caused by many things. Materials such as paint dropped into the pool will stain a pool liner. Stains can also be caused by mold growing underneath the liner or by bleaching from harsh chemicals like chlorine. High metal content in the water can also cause staining. Most stains (other than chlorine and salt) will not reduce the longevity of a pool liner significantly. Treatment of pool liner stains will vary depending upon the type of stain it is.
Pool Liner Wrinkles
Pool liner wrinkles generally happen because of excessive sun, excessive chlorine, or faulty liner measurement/installation. Liners approaching the ten year mark will be much more likely to develop wrinkles caused by chlorine. Upgrading your pool system to a drinkable pool water system will eliminate this issue by removing all chemicals from the water. Excessive sun wrinkles generally occur just below the skimmer or just above the water line. Extra thick insulation under the liner can reduce the effects of the sun on the pool liner. Improperly measured liners with too much material will have wrinkles. You may be surprised to learn that these wrinkles will not actually reduce the longevity of the liner. They are simply a cosmetic issue.
Pool Liner Sun
The sun can have a major impact on the lifespan of the pool liner. It is important to understand that the sun is only an issue when it is excessive throughout the day. The sun is not very often the culprit of liner failure. Cover the pool during the winter with a maxi-mesh safety cover to reduce fading, wrinkles, and vinyl degradation caused by the sun.
Pool Liner Salt
Salt systems are very popular with pool owners today. Unfortunately, the downsides to having salt in your pool water are very costly. Salt is used to generate chlorine in the
water. Chlorine will attack the liner vinyl and printed design from day one. In fact, I recently completed a five year study on pool liner fading rates and swimming pools equipped with salt systems displayed extreme liner fading at the same rate as a traditional chlorinated pool (under 3 years). Salt cause corrosion as well and significantly reduces the lifespan of pumps, filters, and heaters.
Pool Liner Chorine
Chlorine in the water has the same effect as the salt system effects listed above without the extreme corrosion component. Pool liners that hold salt water or chlorinated water will generally experience 50% fading of the pool liner design pattern within 3 years of installation. Upgrading to drinkable pool water is the only way I am aware of to prevent this from happening.
