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 should each of these diagrams contain. Going into the addition,
is a new master bath (toilet, dual sink, seperate shower, and whirlpool
tub), a laundry room (washer and a sink), and two outdoor hose bibs.
Should this diagram, include each of the connections to these pieces of
hardware? Do i need to show the connection sizes and the types? Does
the diagram need to show both floors in one diagram? also how many
fixtures can be on one roof vent?
Any insite on this that any of you can cast, is greatly appreciated.

Not a great example, but an example - http://tinyurl.com/eyro8 Add pipe sizes.

They will expect a professional drawing of the waste/vent design layout.
There are a great number of design details which need to be considered,
far more than can be addressed in a DIY newsgroup.
Get thee to yon library and pull out a few books on plumbing design.
There are even some good ones on DIY projects.
Unless you can enlist some aid from a local plumber who knows
what NJ expects, this could be a drawn-out experience with the town.

I'm sure what they want is pipe sizes and location. There want . waste
pipe, vent, water supply? (hot and cold) Just general diagram of the
plumbing. Should have drawing of first and second floor. I don't think they
care about connection type. They want to make sure your not overloading the
existing system. Basically you want to draw a line ( from point A to B)on
your blueprint like 3" waste show the point of connection and pipe size it's
connecting to, path it follows. Look for blueprint with the plumbing to get
an idea. You might find out you have to change some of the existing system
to ( larger pipe size ) to meet new loads

As Jim suggested, they will probably expect a good isometric DWV
drawing, not an artistic rendering. The library or bookstore should
have examples if you can't find them on the web. Also check out the
books at Lowes or Home Depot. Look for a "Code Check Plumbing" there
for more info.
You will need to add up all the FUs (fixture units) for your fixtures
to determine the vent to roof (VTR) size
