How many times do I have to tell you, there is no sump pump. There was
never any sump pump. It is to stop the sanitary storm sewer from backing

time
on.

No where did you say anything about a sanitary drain.

Anyhow, back to sump pumps. The backflow preventer is typically right
at the discharge line. It's in the sump crock, so it's not a big issue
if it leaks a bit.

Nowhere did I say anything about sump pumps. This is simply a back
flow
preventer with a check valve. The valve is installed in the sanitary
drain
about a foot and a half below the floor in the basement. There is a
box-shaped housing which goes over the top of the valve. There is an
inspection cover which can be unscrewed to check the operation of the
valve.

I had a back-flow preventer installed last fall.

On what?

It works
fine but I have a question. There is usually about 1 inch
of water inside the housing.

What 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?

Depends on what it is, how it's assembled, and what the overall
system
structure is.

If not what do I do
to resolve the problem.

You might start by putting together a clear, concise description of
your
problem and a clear, concise phrasing of what you need to know. I
suspect
it's a sump pump but that's a small part of what needs to be known.

This is the first time you have stated what the "preventer" is for. I
have a "preventer" for my sump pump discharge, so you are at fault for
not stating clearly what kind of a "preventer" you have.
If you knew what it was, then no explanation would be necessary. If you
don't know what it was then you obviously have nothing to add to the thread.
