Signs of a Leak
Before diving into the identification process, it’s essential to recognise the signs that your pool may have a leak:
Unexplained Water Loss: If you’re losing more water than usual, even after accounting for evaporation, you likely have a leak.
Wet Spots in the Garden: Unusual wet areas around the pool can indicate a leak.
Lowered Chemical Levels: If you notice a sudden drop in your pool’s chemical levels, it could be due to a leak diluting the chemicals.
Air in the Pump System: Bubbles or air in the pump system might suggest a suction-side leak.
The Bucket Test
The bucket test is a simple and effective way to determine if your pool is leaking:
- Step 1: Fill a bucket with water and place it on the pool step, ensuring the water level in the bucket matches the pool’s water level.
- Step 2: Mark the water level inside the bucket and the pool.
- Step 3: After 24 hours, compare the two water levels. If the pool level drops more than the bucket level, you have a leak.
Inspecting the Pool Shell and Fittings
- Check for Cracks: Inspect the pool’s shell for visible cracks or damage.
- Examine the Fittings: Look closely at the pool’s fittings, such as the skimmer, return jets, and lights. Leaks often occur around these areas.
- Dye Test: Use pool dye or food colouring around suspected leak areas. If the dye gets sucked into a crack or fitting, you’ve found the leak.
Fixing Leaks
Fixing Surface Cracks
Surface cracks in fibreglass pools can often be repaired with a fibreglass repair kit:
- Clean the Area: Thoroughly clean the area around the crack.
- Sand the Crack: Lightly sand the crack to create a smooth surface for the repair.
- Apply the Resin: Mix the resin according to the kit instructions and apply it to the crack.
- Apply the Fibreglass Mat: Place the fiberglass mat over the resin and smooth it out.
- Apply Additional Resin: Cover the mat with another layer of resin.
- Let It Cure: Allow the repair to cure according to the kit instructions.
Repairing Leaks Around Fittings
Leaks around fittings can often be fixed with pool putty or silicone:
- Turn Off the Pool Pump: Ensure the pump is off before starting the repair.
- Dry the Area: Make sure the area around the fitting is dry.
- Apply Pool Putty or Silicone: Apply the putty or silicone around the fitting, pressing it into any gaps.
- Allow It to Cure: Let the repair cure according to the product instructions before turning the pump back on.
Professional Help
For significant leaks or if you’re unsure about the repair process, it’s best to contact a professional:
- Pool Leak Detection Services: Professional services can accurately detect and repair leaks.
- Warranty Considerations: Check if your pool’s warranty covers leak repairs and consult the manufacturer if necessary.
Preventative Measures
Regular Inspections
Regularly inspect your pool for signs of wear and potential leaks:
- Check Fittings and Seals: Ensure all fittings and seals are in good condition.
- Monitor Water Levels: Keep an eye on your pool’s water levels and investigate any unexplained drops.
Proper Maintenance
Maintain your pool to prevent leaks from developing:
- Balanced Water Chemistry: Ensure your pool’s water chemistry is balanced to prevent damage to the pool shell and fittings.
- Clean Filters and Pumps: Regularly clean and maintain your pool’s filters and pumps to prevent pressure build-up and potential damage.
By following these steps, you can effectively identify and fix leaks in your fibreglass round pool, ensuring it remains in excellent condition for years to come. Remember, timely detection and repair are key to preventing more significant issues and maintaining your pool’s integrity.
