Perfectly fine, don't worry. If you were using it in a pneumatic, you'd have problems.

my cannon is also made of dwv and it has never exploded

[spudshot]

if its combustion and you've built it right, and havent dropped it, no its not gonna explode on you

I should probably point out that fittings & pipe will say that it's DWV even if it's PW, because if you can put pressure in it, you can obviously use it for a drain.
For instance, my 4" pipe is rated to 220 psi, is PW, and is DWV. (Got quite a start one day after I bought it: looked at my pipe, saw a DWV and yelped. I then remembered that A: it said 220 PSI on it B: it said PW on it C: A and B are normal.)

... so you might want to check for a PW as well.
