Well, since it's in the sump pump crock, it ought not be a big

I had a back-flow preventer installed last fall. It works fine but I
have a
question. There is usually about 1 inch of water inside the housing.
When
I open up the inspection cover, it drains away but more enters after a
short
while. My question is this: Is this normal? If not what do I do to
resolve the problem.
