The sump pump in our house has been running constantly for the 12 years we have lived here. It would fill during droughts and in the dead of winter.
Suddenly at the end of this summer, the reservoir is dry.
I don't think there has been a change in the drainage, as the ejector pump is going off pretty regularly. So I'm thinking there is something wrong.
I have read other posts saying that a dry reservoir is good, but I'm worried that it's not good if the ejector is going off. If it's a clogged drain, how do you fix that? Word with the neighbors is that it is a perimeter drain, and that isn't something that clogs easily.
