Using a Johnson Tee in California? Legal?
Trying this again because my previosu attempt dissapeared....so if this question gets posted twice, apologies in advance.
Does anybody know if using a Johnson Tee on a dishwasher will pass code in California (i.e., does it satisfy Cal. Plumbing Code 807.4)? Or do you *have* to use a countertop-style air gap. My understanding is that a Johnson Tee *is* an air gap, and they are UPC approved, and I have seen some vague references to them being used in LA in the past, but can;t find any solid info.
Specifically, I am in SF...but any California feedback would be appreciated. I am also trying to get a straight answer locally, but ammo from real-world examples would be great.
