What question should I ask a plumber? Something is wrong with my plumbing but I am not sure what....

Something is wrong with my plumbing but I am not sure what. My husband said it may be our "stump-pump." There is NO QUESTION that I will hold to have the problem corrected and sewage taken out from lower than my house.

I don't know what to ask them about services, costs, records and so on. Any ideas would be accommodating.

Ask the plumber either he is graduate or not, if underneath graduate he will do it well.
