anti-gravity drip leg

[philjafo]

Eh, thats close enough

[mark beiser]

Hey, at least they had sense enough to put it at a change in direction of gas flow.
It doesn't look like it is a minimum of 4 inches though..

[syndicated]

I think the valve should be upstream of that ... Thing

The last few connections before finally getting the new gas line to the gas valve, you look in the box of fittings sent with you for the job and all you have left is........... the picture above.
Or
My buddy went with me to the big box store to get the water heater and the piping we figured we'd need. 2 six packs later we figure out we're short a few parts. The store is further away than either of us figure we can drive without getting arrested for DUI. Wife wants hot water NOW! We'll fix it tomorrow when we sober up.

prior to my gas license test, the instructor noted that the new code did not mention any length in the new code book. We deferred to the prior book that did list a length, though I thought it was 3".

I have seen a lot of gas supplies that had the Union BEFORE the shut off....

That's not a drip leg, that's an expansion port! What's a drip leg?

Its piped like that so you can unthread that cap and thread in a boiler drain for your hose......thus, a drip leg....drip....drip.......drip.................boo ooooommmmm.

Silly boys. That's not a drop leg. It's a clean out.

[Oldsolarguy]

Well I guess they didn't leak test with a lighter. Otherwise you wouldn't have a pic of lovely craftsmanship there. It drove me nuts, a tech I used to work under would do that. Scared the hell out of me.

Yep. Ran outta 90s.

I saw a tv show on how things are made, they showed quality control at a water heater manufacturer test running a new heater and checking for gas leaks with a lighter. I couldn't believe they would show that on tv, they didn't say that's what they were doing, but why else would you pass a flame over the connections.

I ran a gas line last year and caught a whiff when I was done. I had struggled slightly when lining up the union and thought I would check there first. But I said this out loud and before I could move the senior tech had his lighter out and lit the small leak at the union. Nice little blue flame.
