So I have 1/2" black pipe stub out in the middle of my firepit. They put a 4" vertical piece of pipe at the elbow but I need to add 12" of pipe to get the fire ring to the proper height. We are putting gravel in the pit 3" from the top and then fire glass (2-3") over the fire ring. The issue is the pipe is not plumb so the ring is 3/4" higher on one side. Can I use flex to make the connection from the black pipe to the Fire ring so it's level? Will I reduce the gas flow using flex vs 1/2" black pipe?

is this fire pit outside? how did they run black pipe to it? if its outside the gas pipe at least should be galvanized or it will rot out and you will get a gas leak..

They used 1" PE gas pipe from the meter underground to the valve on the side of the fire pit and the above ground stub out. They just did not ensure the vertical pipe was plumb. It's centered in the firepit with is good but one side of the fire ring is 3/4" higher than the opposit side. Not sure if the mason messed it up or it was not plumb to begin with.

I will try the 45 and hopefully the will bring it plumb. If not its flex or the ring will be uneven, hopefully the will not impact the flame.

Tried the 45, it tilts the pipe the opposite way too much. So options are leave it out of plumb its, actually only about 1/4" out of plumb in a foot. The fire ring will be buried under 2-3" of glass, so hopefully the flames will not be different on each side?

Option #2 is 12" piece of SS flex gas line going from the black pipe to the fire ring, then I can level the fire ring on the gravel.

Any downside to flex? They make a whistle free and high capacity. Not sure if there is any difference between they?

Last question, using pipe dope, on the connections, how am I to do the soap water test on the connections if the fire ring is connected as I can't plug the holes?

Thx

Here are some pictures. Let me know what you think. I want to keep the fire ring centered within the pit. I figure I could be done with black pipe but that will be a lot of connections. Would have been nice had they installed this plumb, lol.

Easy peasy. (Use approved dope/tape on all male pipe threads).

- cut the tape off half way down the 90
- remove the 4" nipple
- turn the 90 almost 45° (but not quite because you'll plumb it up later)
- add a 1/2 " X 1 1/2" nipple and 1/2" 90 and tighten, but not quite all the way because you'll plumb it up later.
- add a 1/2 X 45 with a nipple long enough to centre the fire ring and tighten in line with the 90
- add the final nipple (it'll be shorter than the 12" you had, maybe ~10"?)
- plumb up the line by tightening the 90's
- cap the nipple and soap test
- wipe dry and wrap with approved tape (polykin, tbt20, Denzo, etc)


Boom. Two extra fittings.

Okay I tried to move that 90 at the bottom, that thing is not moving, I just can't get adequate leverage as its so close to the floor.

So, here is a ******* solution, there is some play with the pipe I can make it nearly plumb by pushing down on the high side of the fire ring. I could just put a piece of pipe halfway up the vertical pipe that braces between the inside wall of the fire ring and the pipe?? Not sure if that's bad for it? It not flexing it a lot, maybe 1/4". I know, not the best fix but it worked as long as there is no long term issue for the pipe?


Other than that, it flex pipe, or I need to call in a pro.

I will call in a pro, thanks for the advise. Another question, my gas line is 1.5" PE, guessing about 90-95 ft run to pool heater. Fire pit is off the same run but about 75-80 ft dorm the meter. Heater is 400btu, fire pit burner is 150-200btu. So if both are running on high that's 600btu, I think that's still fine for the run and pipie sizing I can't imagine both running at max.

90 ft of 1 1/2 will support 490,000 btu....so it was piped correct for the pool heater..not with the fire pit
