Default Two failed water heater inspections drip leg

The way I have installed drip legs on water heaters is short nipple out of control valve. Tee. 6" drip leg and cap. Gas flex into top of the tee. Gas valve before flex. Was told today on both heaters. Drip leg needs to be before gas shut off valve. Flex after drip leg. Is this new, or have I been doing it wrong for twenty years? One inspection was in county, the other in city. Two separate jurisdictions.

Makes no sense to me the way they want it. From the tee up it should be union or flex than valve. What is the point of having the valve between the drip leg and the gas control?

Los Angeles County has adopted this **** too.
A drip leg techingly in a sediment trap, 3? nipple, tee and a cap. Now it must be before the valve!
Pain in the ass

I'm tripping. Wasn't the point of having drip leg after shut off valve so the drip leg could be serviced with shutting the entire house down? I mean, I'm gonna do what I have to to pass inspection. I'm just trying to figure out the logic to the new way. Seems like the way I've been doing it works perfect.

You're absolutely correct. It make no sense. I asked several times today with no answer other than, "that's the way we want it now". Mmm, ok.

My Master would ask the inspector to pull out his book and prove it. As Ive said many times, hes an *******, but hes a damn good friend and mentor!

Shut off valve should be in line upstream of everything else in order to service the other components as you stated Panther. But hey, you're in California right?

This particular set up was in Gainesville, FL. They wanted a tee after the regulator. That is where I had to put a manometer to get my inspection.

Believe it or not, but the city would not accept anything but a U tube manometer. They won't pass a gas line rough-in inspection with a digital manometer.

that is a total joke but if it makes the inspectors feel like they are big shots..in their little neck of the world, then its best to play along with them and let them feel like big shots......

Exactly the same order as we do it here. That is pretty much the only way I have seen it done. We do though also go shut off valve, tee with drip leg and then flex appliance connector between the tee and the control valve if we can't make the old hard piped gas line line up with the new heater using just some nipples. We don't thread pipe it just takes too long and is too messy. We can and I have threaded pipe before but as a general standard we just don't do that any more.
