Fiberglass pools are a popular choice for homeowners who want a cost-effective swimming pool in their backyard. These pools are best known for their durability, ease of maintenance, and quick installation.

However, fiberglass pools are not immune to problems. This article explores some common issues that fiberglass pool owners may encounter.

Spider cracks in the gel coat

These cracks are tiny, hairline fractures that resemble spider webs and are typically found on the surface of the gel coat. They are often caused by a combination of factors, such as exposure to sunlight, fluctuations in temperature, and stress on the pool's surface.

However, human error can also contribute to this problem, including poor manufacturing, improper protection during shipping, and incorrect installation. Although spider cracks don't usually affect the pool's structural integrity, they can be unsightly and may lead to water leaks if left untreated.

Bulging pool walls

In some cases, the walls of fiberglass pools start to curve outward, away from their structure. The causes may vary but include improper installation, water pressure, or sand backfill.

Although sand backfilling is very common in the pool installation process, it may create problems in the future when it mixes with water and becomes liquified. The liquefied sand then starts to settle and compact on its own, creating significant pressure on the walls and causing a bulge.

Addressing this issue as soon as possible is crucial to prevent further pool damage and potential safety hazards.

Discoloration and stains

Discoloration may occur due to various reasons. Exposure to sunlight, algae growth, and chemicals may cause the color to fade or become yellowish over time. High levels of iron and copper in the water can also create stains (typically green or blue) on the pool surface.

However, discoloration is less likely if the pool manufacturers apply high-quality materials and coating in their production process and the homeowners maintain proper pool water chemistry and conduct regular cleaning.

Settled plumbing leads to leaks

When the pool's plumbing system settles due to downward pressure from the self-compacting sand backfills, the pipes may become misaligned or disconnected. If this happens, water can leak out of the pool through the plumbing system, causing damage to the surrounding area.

It's essential to use backfill materials that don't settle after the pool installation, such as clean 3/4-inch stones or gravel backfill. Regular pool maintenance can help detect the problem early and prevent it from developing into a more complex issue.

Call a reputable pool technician

If homeowners notice any problems in their fiberglass pool or want to install a new one, it's best to call a reputable pool specialist. They have the skills and experience to quickly diagnose the problems to prevent further damage or install a new fiberglass pool correctly and safely.

Also, ask them to perform a regular inspection to detect potential issues early to save time and money. Don't hesitate to contact a qualified pool technician to ensure one's pool remains in good working condition for years to come.
