Upon arrival, I found the basement water level at an inch, though it had previously reached knee height. I thoroughly inspected the plumbing system, which was accessible due to the open ceiling and basement size. No leaks or drips were observed in the drainage system when the house was fully operational. Both water heaters appeared functional, though they had absorbed some water. The sump pump, three years old, was initially off, but it activated immediately upon turning the breaker back on, effectively managing the water. The grinder pump also operated intermittently. Based on these observations, the flood was likely due to a tripped sump pump and grinder pump, possibly caused by a storm-induced power flicker. The client plans to have HVAC inspected for proper functioning.
