Why Drain a Fibreglass Pool?

There are several reasons you might need to drain and refill your fibreglass pool:

1. Water Quality Issues: If your pool water has become imbalanced and you’ve been unable to correct it, draining and refilling might be the best option.
2. Repairs or Renovations: If you need to carry out repairs or resurfacing, draining the pool is often necessary to access the affected area.
3. Winterising: In colder climates, draining the pool can prevent freezing water from causing damage.

Whatever your reason, it’s crucial to do the job safely to avoid structural damage to the fibreglass. Let’s look at the process step by step.

1.    Check Local Regulations and Permissions

Before draining your fibreglass pool, it’s essential to check your local regulations and ensure you’re complying with all legal requirements. Many areas have specific rules about how and where pool water can be disposed of.

• Stormwater and Sewage Disposal: In some regions, discharging pool water into the stormwater system or sewerage system can be illegal. Pool water may contain chemicals like chlorine, stabilisers, and algaecides, which can be harmful to the environment..
• Water Conservation Measures: In drought-prone areas or during water restrictions, there may be rules against draining your pool or limits on how much water can be used.

By researching and adhering to local regulations, you can avoid any legal complications and ensure that the process is done responsibly and safely.

2. Prepare for the Drainage Process

Proper preparation prevents damage to your pool and surrounding areas. Here’s what you need to do:

• Inspect the Pool: Check for cracks or visible damage. If needed, carry out repairs before draining.
• Clean the Pool: Remove any debris to make the process easier.
• Check the Equipment: Ensure your filtration system, pump, and other equipment are working properly.

3. Start Draining the Pool

Draining a fibreglass pool is simple but requires precautions. Here’s how to do it:

• Turn off the Pool Equipment: Ensure the pump, filter, and heater (if applicable) are turned off.
• Use a Submersible Pump: The most effective way to drain a fibreglass pool is with a submersible pump. Place it in the deepest part of the pool and attach a hose to direct water to a suitable drainage point.
• Monitor the Drainage: Keep a close eye on the process. Avoid letting the pool drain too quickly to prevent damage.

4. Important Precautions While Draining

To protect your fibreglass pool, take these precautions:

• Never Drain Too Quickly: Draining too quickly can cause the fibreglass to warp or crack. Drain over a few hours rather than all at once.
• Avoid Draining Below the Skimmer: Drain the pool to the level of the skimmer to prevent the fibreglass shell from lifting, especially in areas with high groundwater.
• Groundwater Levels: If your pool is in an area with high groundwater levels, take extra caution. In some cases, pumping water from around the pool may be necessary.

5. Refilling Your Fibreglass Pool

Once the pool is drained and repairs are done, you can refill it:

• Start Filling Slowly: Begin refilling the pool slowly to avoid stressing the fibreglass shell. Use a garden hose or suitable water source.
• Monitor the Water Level: Keep an eye on the water level to ensure it rises evenly. This will prevent damage to the fibreglass shell.
• Check for Cracks or Issues: As the water level increases, inspect the pool for any signs of damage. If you notice any issues, stop filling and contact a pool professional.

6. Balancing the Pool Water

Once your pool is refilled, balancing the water chemistry is essential for a healthy swimming environment. Here’s how:

• Test the Water: Use a pool water testing kit to check the pH, alkalinity, calcium hardness, and chlorine levels.
• Adjust the pH: The pH level should be between 7.2 and 7.6. Use a pH increaser or decreaser as needed.
• Add Chemicals: Once the pH is balanced, add chlorine or other sanitizers to the water.
• Run the Filter: Turn on your filtration system to circulate the chemicals and ensure proper filtration.

7. Maintaining Your Fibreglass Pool After Refilling

After refilling your pool, regular maintenance is key to keeping the water clean and clear. Regularly check the water chemistry, run the filtration system, and inspect the pool for any signs of damage. Proper maintenance will help extend the life of your fibreglass pool and ensure a safe swimming experience.

8. Consider Professional Help if Necessary

While draining and refilling your fibreglass pool can be a DIY job, it’s not always easy or risk-free. If you’re unsure about any part of the process, particularly in areas with high groundwater or if there’s significant structural damage to the pool, it’s advisable to seek professional assistance. Pool technicians have the experience and equipment to handle these tasks safely, and they can also offer advice on repairs and maintenance to keep your pool in optimal condition.

Draining and refilling a fibreglass pool may seem like a complicated task, but by following the right steps and taking necessary precautions, it can be done safely and effectively. Always ensure you follow local regulations, use the proper equipment, and monitor the process to prevent any damage to your pool.
