IPC DWV quiz

[PrecisionPlum]

I would like to test myself on IPC DWV systems and to be able to check for correctness.

Does anyone know of a site where you can do this?

Fodo,

Thank you for your response. I am looking for something along the lines of required drain sizes, distance, vent location, etc.
I.e., bathroom group and how far the fixtures can be placed, when vents need to be added and where, etc.

Thank you again Frodo.

I am thinking along the lines of the DWV isometric drawings.
Perhaps where you would fill in the blank for what the stack
and branch drain size should be given the fixtures and their
location. Also vent locations and minimum size, etc.

I.e. What to do when a WC is before a Lav on a branch drain.

I would like to run through DWV scenarios to develop my
comprehension of what needs to be done given a DWV situation.

2 ways to plumb waste lines
stack fittings and flat
stack fittings, in my humble opinion, is the way to go if you have the room


I.e. What to do when a WC is before a Lav on a branch drain.

you throw a wye in as shown,
if the vent is a dry vent, the wye has to be rolled
if the vent is a wet vent ie a lav drains into it
it does not have to be rolled.
reguardless the base of a vent must be before the fixture so that the base of that vent can be washed.
so that stuff does not build up and cause a clog

minimum branch size for a toilet is 3''
minimum branch size for a every thing else [in a house] is 2''
1 1/2'' is not used by professionals as a waste pipe
except>>> for arms in the wall to sinks
tubs and showrs are 2'' you reduce to 1/1/2 for a tub drain by using a 2 x 1 1/2 bushing on the 2'' p trap

a toilet gets a 2'' vent
sinks get 1 1/2'' vents
washing machines get 2'' p traps and 2'' stand pipe 1 1/2'' vent
