caryseidner Posted June 26, 2009 Report Share Posted June 26, 2009 I have noticed this a few times. A slice in a PVC sump pump discharge line, below the float level. It seems like an odd place for a plumber to have made an accidental cut. Does anyone know why this would have been done?

Click to Enlarge 54.08 KB I am not sure why but if I was to guess © I would think one fof the following answers: a) pressure relief to make sure that the pump does not blow the fittings of the PVC. b) if the pump was to run the pit dry the cut would allow the water in the riser to flow back into the pit, which would make it much less likely to burn up the pump. c) combination of a, and b. d) something entirely different.
