Swimming pool liners will fade due to two main causes.
- UV Rays from the sun
- Chlorine Bleaching
Conventional wisdom says that UV rays cause about 50% of the fading and chlorine bleaching causes about 50% of the fading in pool liners. However, a five year study conducted by Lazy Day Pools between 2006 and 2011 concluded that 99% of pool liner fading is due to chlorine bleaching and only about 1% of fading is due to UV rays.
Lazy Day compared the fading which occurred in five year old pool liners installed on pools equipped with salt systems in July 2006 with five year old pool liners installed on pools equipped with “drinkable pool water systems”. The result was that the liners exposed to salt systems experienced almost total fading over the five year period while the drinkable pool water pools showed no signs of fading at all!
Whereas salt systems use salt in the water to generate chlorine; Drinkable pool water systems do not use salt or chlorine to clean the pool water. This lack of harsh chemicals means that the fading normally associated with pool liners does not occur which in turns causes the pool liner to last longer.
Drinkable pool water systems are expensive. These systems may be worth the expense during new pool construction or to prevent pool liner fading and increase the longevity of the pool liner. Their are 2 drinkable pool water systems available for purchase. The turbo unit is available for around $3000 and the programmable unit is available for around $5800. The programmable unit requires almost no management and significantly redusces the potentila for human error.
This study was an internal study conducted by Lazy Day Pools. It was not a peer reviewed study and is not considered a scientific study although the results of the study were very clear. For more information on this study see lazydaypools.com.
