More pool leak questions

Quick answers to questions we are often asked. All 56 are on our pool leak FAQ page.

Can a pool crack leak?

Yes. Cracks can leak if they pass through the waterproof structure or connect to a void behind the pool shell. Some cracks are cosmetic, while others are active leak paths. Dye testing and structural assessment help determine whether the crack requires local repair, stitching, fibreglass lining or more extensive renovation.

Can soil movement cause pool leaks?

Yes. Ground movement can stress pipe joints, pool shells, paving and fittings. This is common where drainage is poor, soil is unstable, or previous repairs were not properly compacted. Movement-related leaks should be diagnosed carefully because simply sealing the visible crack may not address the underlying cause.

Can pool leaks affect foundations or retaining walls?

Large or long-term leaks can saturate soil and contribute to movement around structures, especially where drainage is poor or the property has reactive soils. Not every leak causes structural damage, but persistent water loss near walls, foundations, paving or retaining structures should be treated seriously.

Can a pool leak only at a certain water level?

Yes. A pool may drop until it reaches the level of the leak and then slow down or stop. This often happens with leaks at lights, weirs, return jets, tile lines, cracks or surface defects. The stopping level is an important clue because it tells the technician which fittings and areas require closer dye testing.

What is dye testing?

Dye testing uses coloured dye near suspected leak points such as lights, weirs, aimflow jets, cracks, steps, mosaics and surface defects. If the dye is pulled into an opening, it indicates active water movement through that point. Dye testing is useful for visible or accessible leaks, but it must be done carefully with the water calm and circulation off.

Can pool leaks be repaired permanently?

Many leaks can be repaired long term if the correct cause is identified and the repair method matches the defect. However, old surfaces, unstable ground, poor previous work or multiple hidden leaks can complicate guarantees. A proper diagnosis gives the best chance of repairing the correct problem first.
