Accolades

"Heavy rains last night. This morning a 110 db screech pierced my house. I went to the sump and found that the pump's power cord wrapped so that the float could not actuate the motor. 30 seconds later, the pump was working and a potential flood was averted. If I could give it 10-stars, I would."
