Owning an inground vinyl liner pool is a fantastic way to enjoy the outdoors, cool off in summer, and create a space for family fun and relaxation. But like any major investment, your pool needs the right care to stay beautiful, functional, and long-lasting. Unfortunately, many pool owners especially those first-timers make common mistakes that can lead to costly repairs and unnecessary frustration. Metropolitan Pools will cover some of the most common mistakes inground vinyl pool owners make, and how to avoid them.

Ignoring Water Chemistry

Skipping water testing or overusing chemicals. Vinyl liners are more sensitive than concrete or fiberglass, so improper water balance can cause fading, wrinkling, and even liner damage. Many homeowners either neglect regular testing or overcorrect with too much chlorine or acid. Test your water at least once a week and maintain proper pH 7.2 to 7.6, alkalinity 80 to120 ppm, and chlorine levels 1 to 3 ppm. Consider using a digital testing kit or bringing samples to a pool professional.

Letting Debris Sit in the Pool

Leaving leaves, dirt, and other debris in the water. Leaves and organic matter not only look unsightly, but they can stain vinyl liners and affect your pool’s chemical balance. Letting debris sit too long increases the chance of algae growth and can reduce your liner’s lifespan. Skim the pool daily, vacuum weekly, and invest in a quality pool cover or automatic cleaner to minimize buildup.

Draining the Pool Without Professional Guidance

Draining the pool completely on your own. Vinyl liner pools should rarely, if ever, be completely drained without a professional. Draining can cause the liner to shrink, wrinkle, or tear. It may also lead to structural damage due to pressure changes from the surrounding soil. If you need to lower water levels or perform maintenance, consult a pool technician first to determine the safest approach.

Delaying Vinyl Liner Repairs

Ignoring small tears, wrinkles, or leaks. Tiny tears or pinholes in your vinyl liner may not seem like a big deal, but they can quickly expand and cause major damage, leading to expensive replacements. Inspect your liner regularly for signs of wear and address any damage immediately with proper vinyl patch kits or by calling a professional.

Skipping Regular Maintenance Tasks

Only reacting when problems arise. Waiting until your pool looks cloudy, smells strange, or shows signs of algae is already too late. Without a consistent maintenance routine, your vinyl liner will degrade faster. Create a weekly maintenance checklist, including testing water, brushing walls, checking equipment, and monitoring water levels. Consistency prevents major issues.

Using the Wrong Cleaning Tools

Scrubbing vinyl liners with abrasive brushes or harsh chemicals. Vinyl is more delicate than other pool surfaces, and abrasive tools or inappropriate cleaners can scratch, fade, or weaken the liner. Use soft-bristle brushes and vinyl-safe cleaners only. Avoid metal brushes, pressure washers, or generic household cleaners not designed for pools.

Delaying Liner Replacement

Waiting too long to replace an aging liner. Vinyl liners typically last 7 to 12 years. Pushing beyond that window can lead to sudden failure, leaks, or costly damage to your pool structure. If your liner shows signs of fading, brittleness, frequent leaks, or stretching, it may be time for a replacement. Planning ahead saves stress and money.
