hello all, i am building an addition on to our house in NJ. I have
applied for all the permits, and have been told that they are all ok,
except for the plumbing. They asked that i supply "a proper sanitary
and vent riser diagram".


What they want is called a "plumbing isometric". Here is a web site with
symbols and examples:

Click on the links farhter down the page to see examples. I just turned in my
isometric using this site as a guide and things went fine with the inspectors.

Right. Much better link than the one I posted. They're not looking
for extreme detail. If you have any doubts ask someone if you can look
at a set of drawings that was approved. Usually they're looking for
pipe size, valve locations, cleanouts, etc., not types of fittings as
that's covered by code.
