Good water tank overflow control alarm: Installed for house overhead water tank ,and is functioning well. Connected to domestic single phase submersible motor starter. Hence no need of a separate switch to switch off alarm. The moment starter is pressed off, the unit also gets off - ycsreddy, Verified Purchase - Amazon, 25 June 2023
