My biggest problem is that my Wilkins 720A (http://www.zurn.com/operations/wilkins/pdfs/installation/IS720A.pdf) was not installed correctly by me ... at least according to Wilkins.
Basically to make the plumbing simple, the backflow preventer is about 20 degrees off of horizontal. The tech support people at Wilkins tell me that any inspector (there won't be any) would not approve. Frankly, I don't care about inspection. I do care about contaminants flowing back into my home's potable water system.
So, will being 20 degrees off of horizontal really cause a problem? I'm going to fix it, anyway, but I'm just curious.

The installation sheet says that the 720A needs to be 12 inches above the highest outlet. Does that include the "spray heads on risers" that could be a few feet off of the ground?

What's the basic idea about testing the backflow preventer? How often should it be tested? Can I do it?
