    Hey guys, I have built a water feature on my patio. It is a cinder block pit 4X2 and 20" high. I have plumbed a gas line in it. My plan is to fill the pit with water and light the gas after it bubbles to the surface.. my gas line is about 5" under water (it has a 17" log igniter attached). I want to ignite the natural gas on the surface of the water: however, it will only stay lighted as long as I have a flame present. It goes out as soon as i remove the flame. any help would be appreciated.

    You will have to play with the gas flow. You need quite large bubbles. You can play with the number and size of the holes in your feed line for starts. Temporarily block some holes to see if you get better flow. Then you can play with the opening size. I would think though that it would be safer to have a constant igniter flame though.

    I have never seen one where it bubbles right though the water, seems like it would be kinda hit for miss. I personally would get a rig from a place like ground effect and mount it just under the surface.

    Maybe some pic would help (also kinda want to see it working too ;) )

    on a related note have you guys seen the setup where you take a tube a seal one end with a speaker, drill holes in the top and feed gas from the other. Igniting the holes and then playing music you get to see the sound waves in the flames--pretty impressive
