Hi all
I'm wondering about the proper way to ensure water does not get in where wall penetrations are made for things like electrical and plumbing
Should I box out the opening like it was a window and add a drip edge behind the WRB?

Thanks for the links Alan. I figured there must be commercial products out there to do this. I did some more searching and found this one too http://www.quickflashproducts.com/index.html
