Twice in the last 15 years, the pump float switch got tangled and failed to turn the pump on and caused minor flooding. The safety switch now rings a doorbell when the tank level gets too high (pump float switch stuck). What I would like is to add is a signal when the pump goes on. Just some positive feedback that all is OK. My first thought is to add small lights (maybe green bulb) in the drop ceiling. Any other ideas on what I could do.
