Re: Sump Pump running constantly and spraying water back into pit
I know this is four years later but I thought it'd help anyway. I was looking for clogs in the pump itself (Small 1/3 horse electric sump - Flotec fpmm3600d) I noticed the pressure would reach about 4 feet up the pipe - 1" corrugated plastic. I went outside (Buffalo, NY in December) and the pipe was frozen like a freezie-pop. I didn't know that a straight pipe sloped from the middle could still have 100% water blockage. So I brought it inside to thaw.
