I got a 1/2 gas line wedged against a piece od wood... its vibrating when my furnace is running. I want to sandwich a piece of hose between them to quiet it. In order to do i will have to apply some force to the pipe, pulling it downward as i cant get to any hangers to loosen. Just need enoigh space to slide the hose in.

Is it a bad idea to force it?

How about a piece of wood shim between the pipe and wood and gently tap on the thick end of the shim to create the space you need for the hose?

That should work, great idea thanks

WHY is it vibrating? Is it because of the fan's vibration, or from the gas flowing through the pipe? Maybe you should be trying to ELIMINATE the vibration, instead of just trying not to hear it.

Im not sure why... i think it could be tje gas flowing... it only occurs with the burners on. However, it could be mechanical since the inducer is running at that same time... i cant figure it out but i know it stop when i decouple the pipe.


Hypothically, could you do chinups on a iron gas pipe? How secure are threaded connections?

Let me ask this..... is it bad practice to rigidly strap gas line to ceiling joists?

A number of years ago i added strapping to the piping, like one every 6 feet... theres 45 feet of it. Prior to that there might have been 2 straps between the appliance and where it enters the house through the sill plate area. Was like that for 50 years before i figured it needed more. There is no flex pipe either, so from gas meter to gas valve it is solid.

No it is not bad practice to secure iron gas pipe, most people use it as a clothes hanging rod, now if you can hear a vibration from the actual movement of gas through that line run because the pressure is WAY too high and I highly doubt that its probably more like the motor vibrating or the access door is not shut properly

i say bad practice thinking your supposed to decouple the gas line from the joists somehow to prevent mechanical noise.

As far as the gas itself making noise, I tested incoming pressure at 6-7"wc and the manifold side of furnace valve is 3.5", so i think its mechanical too. But standing next to the furnace you do not notice anything out of the ordinary.

hypothetically - yes, you could


in the 'olden times' hangers were 'supposedly' installed to withstand 250# + the weight of the piping they supported


today, the 'piping' itself is fragile .........................

Gas is under OUNCES of pressure. Gas flow would not cause vibration. An out of balance fan could cause vibration. Secure the pipe to the wood with a 2-hole strap.

when hanging gas pipe below joists, i use reznor hooks.
