Start with the bucket test to rule out evaporation. Place a bucket of water on the first step, mark the water level both inside and outside the bucket, and wait 24 hours. If the water in the bucket drops as fast as the pool, it is evaporation. If the pool drops faster, there is a leak.
Next, check whether the level drops differently with the pump on or off. If the pool loses water mainly while the system is running, that points to the pipes or fittings under pressure. If it also drops with everything switched off, the leak is more likely in the shell itself.
Common spots are the skimmer and inlets, the seals around lights, cracks in the floor or walls, and the plumbing. A coloured test dye next to a suspected crack can reveal whether water is being drawn in there.
Pinpointing a hidden leak is skilled work. We assess the situation on site and advise whether a targeted repair is enough or a seamless waterproof finish is the wiser choice. Feel free to request a no-obligation inspection.
