Can the plumbers anwer this one for me?
I'm trying to get an idea of the differences in codes we are using, and where they are being used. It may help us to come up with better help in giving better local answers to local questions.

What state do you plumb in?
Which plumbing code do you work under?
Are there any modications to your code?

For me, the answer would be'
Washington State
UPC, Uniform Plumbing Code.
