Trace the water before choosing a repair
A puddle beside your heater is a reason to investigate, but it does not tell you which component is leaking. Water can travel along a pipe, collect under a cabinet or run across the equipment pad from somewhere else. We approach pool heater leaking water requests by separating the apparent location from the actual source. That distinction matters because a connection repair and a damaged heat exchanger involve very different decisions.
You may notice dampness only while the pump runs, after heating begins or when equipment has been switched off. Each pattern provides context without proving a cause. We ask what you have observed during ordinary use rather than asking you to recreate the leak. If water is approaching electrical equipment, keep away from the affected area and seek appropriate help instead of stepping into the puddle to obtain photographs.
