Customer has a 16x32, 6'deep, salt pool - steel walls, fiberglass steps. Hayward Super Pump and SD40 Sand filter.
On Saturday, customer checked pool, everything fine. Saturday night, strong thunder/lightening storms in area. Sunday morning, customer went out to clean pool and found black "stains" on light, returns, skimmer, main drain and step jets. Appearance resembles smoke/charred marks from fire (like when a plug sparks in an electrical outlet).
Has anyone experienced this kind of reaction after a storm? Is it possible that lightening struck the pool and caused "fire" to come through pipes? Breaker not tripped. Pump and salt system working. GFCI was replaced since today, but not sure if it worked properly before storm.
