Is it possible to drain a fibreglass pool?

Wondering if it's possible to drain a fiberglass pool? Fiberglass pools are a popular choice for homeowners due to their durability and low maintenance, but there may be times when you need to drain the pool. In this informative article, we discuss the process of draining a fiberglass pool, including when it's necessary, how to do it safely and important considerations to keep in mind. Whether you're performing maintenance work, making repairs, or simply need to lower the water level, understanding the proper procedures for draining a fiberglass pool is essential to maintaining its quality and longevity.

Water Level in Fiberglass Pools

Maintaining the proper water level in a fiberglass swimming pool is essential to ensure its longevity and efficiency. Owners of fiberglass pools must ensure that the water is always at least 3 inches above the bottom of the pool, especially above the bottom of the skimmer opening.

This prevents damage to the filtration system and allows proper skimming of floating debris. On the other hand, if the pool water level exceeds the top of the skimmer, it's important to drain the excess to maintain cleanliness. This can be done by brushing the sediment towards the main drain.

How to maintain water level

For owners of fiberglass pools, understanding the importance of maintaining the water level is essential. The water should ideally be in the middle of the rectangular skimmer plate on the pool wall. Too low a level can cause the circulation pump to malfunction, resulting in costly pump damage, while too high a level can reduce the skimmer's effectiveness in keeping the pool clean.

Water level monitoring

Keeping a close eye on the water level is essential. For fiberglass poolsIt's vital to keep the water at least 3 inches above the bottom of the skimmer. Regular monitoring helps ensure that the water's chemical balance remains stable, as fiberglass pools have an inert surface that requires fewer chemical adjustments.

It also helps protect pool equipment and extend its lifespan. Vinyl-lined pools require a water level that completely covers the bottom of the shallow end, with a minimum depth of 12 inches above the pool bottom in the shallow end.

Using a Sprinkler Hose for Adjustment

When the water level needs adjusting, using a garden hose is a simple and effective method. It's best to fill the pool to the required level with fresh water, and you can use a garden hose with a pressure nozzle to achieve this. This tool is also useful when cleaning filter cartridges.

However, it's important to avoid using a garden hose for tasks intended for submersible pumps, such as emptying the pool, as this can damage the pump. After filling a pool with a garden hose, it's crucial to test the water for chemical balance and make any necessary adjustments before using the pool.

Should you drain a Fiberglass Pool?

Emptying a fiberglass pool is generally not recommended unless absolutely necessary, and should be done with care. Fiberglass pools are designed to be installed in the ground, with the surrounding soil providing support. Emptying the pool can lead to a variety of problems, including:

  • Buoyancy: Fiberglass pools are lighter than concrete pools, and when emptied, can cause buoyancy problems. This can cause the pool to lift off the ground, resulting in structural damage.
  • Cracking: The structural integrity of a fiberglass pool relies on the hydrostatic pressure of the water inside. Emptying the pool can result in uneven pressure on the pool walls, potentially leading to cracking.
  • Coating damage: Fiberglass pools often have a gelcoat finish that can be damaged if the pool is drained and left exposed to sun, air and other elements for an extended period. This can lead to the need for costly repairs or re-enameling.

If it's necessary to drain a fiberglass pool for repairs or maintenance, it's crucial to follow proper procedures and take precautions:

  • Professional Assistance: Consult a professional or the manufacturer for advice on draining and filling your specific fiberglass pool.
  • Appropriate timing: If draining is necessary, schedule it during cooler periods to minimize the risks associated with prolonged exposure to the sun.
  • Backfilling: In some cases, backfilling the pool with water before draining can help counteract flotation problems and reduce the risk of damage.
  • Regular maintenance: Regular maintenance of water chemistry and pool components can reduce the need for draining.

Always consult a professional to determine the best course of action for your specific situation, and follow his or her recommendations to ensure the longevity and structural integrity of your fiberglass pool.

Why choose a Fiberglass Pool?

The risks of draining a fiberglass pool

There are inherent risks in emptying a fibreglass pool, and these can be avoided. pool owners should not be overlooked. Often considered a simple task, the consequences of draining this type of pool can be serious if not carried out correctly.

Potential damage to the pool structure

The risk of damage is greater with fiberglass pools, which may be more susceptible than other types of in-ground pools. The structure and lining of the pool are at risk, especially if pool water floods the ground and undermines the foundation.

Maintaining the right water level is also crucial to pool functionality; too low and the circulation pump can be damaged, too high and the skimmer becomes ineffective. What's more, prolonged exposure to inappropriate water chemistry and high levels of disinfectant can damage not only pool equipment, but also the pool's gelcoat, potentially voiding warranties and becoming expensive.

Risk of groundwater disturbance

A hidden risk that lies beneath the surface is the water table. Emptying a fiberglass pool without understanding the local water table can lead to catastrophic results. Disturbing the water table can increase the risk of flooding and soil movement around an in-ground pool, leading to structural problems such as cracks and deformation. Areas with high water table levels present an even greater risk during emptying, with the rising hydrostatic force having the potential to crack the pool floor, leading to costly repairs.

Invest in a Quality Fiberglass Pool

Visit fiberglass pools are synonymous with durability. Their popularity isn't just about cost; it's also about the quality of the bathing experience. With their smooth, non-porous gelcoat surface, these pools require less frequent cleaning. This unique feature minimizes the need for harsh chemicals, ensuring an environmentally-friendly pool water environment.
