Vinyl Pool Liners

Vinyl pool liners

The most common question we get is how long should a liner last. Several factors contribute to liner longevity. Other than physical damage the most important thing is avoiding chemical abuse.

On average, the typical liner should last at least 8 years. Here in the Northeast pools are typically covered for 4 to 6 months of the year so with proper care, you can expect it to last maybe 14 to 16 years. Some liners have been around for 20 years but that is the exception.

Keeping your pool chemicals in balance is one of the most important things you can do to help your liner last for many years.

Chlorine Level + PH = Faded and Damaged Liner

Ideal Chemical Levels

PH 7.4 – 7.6
Total Alkalinity 125 – 150
Total Hardness 175 – 225
Free Chlorine 1.5 – 3.0
Total Chlorine 1.5 – 3.0

Chemical use tips
• use quick dissolving chemicals or liquid.
• Premix powdered chemicals in a bucket of warm water then distribute
• vacuum up un-dissolved chemicals.

Dumping in chemicals and allowing them to remain in contact with the liner can cause damage. Avoid prolonged contact of un-dissolved chemicals on the pool bottom.

A faded liner usually means overly aggressive use of shock or chlorine treatment. Try to keep your chlorine level from routinely going over 3 PPM unless shocking your pool.

Circulate your pool water for 48 hours after shocking. Also keep the pool uncovered for a few days to allow the high chlorine level to dissipate. Keeping your pH and chlorine at normal levels helps avoid a faded and damaged liner.

Empting A Pool

Never empty a vinyl lined pool!

Liners shrink when the pool is empty, making it difficult or impossible to reposition and refill. Pool liners lose plasticizers with age and become stiff. Once the liner is allowed to shrink they don’t usually stretch back into place. When the pool is refilled the seams will most likely fail.

Additionally the weight of the water in a pool helps hold the sides in position, empty pools have been known to collapse.

If you must empty your pool it is best done using the service of professionals.
