Browse Forums General Discussion 1 Sep 07, 2012 1:57 pm I noticed this pretty much when we moved in. Happens especially when the wind is strong. Sounds like the wind comes into gas(?) pipes and makes that noise ... hard to explain, but clearly audible. You can hear it in the kitchen and it comes from the gas cooktop. Anyone else has this? Is this a real problem?? My signature is distracting people from my wise posts ... Re: Wierd, wierd noise in (I think) gas pipes 4Sep 08, 2012 10:41 am You're so right, jodge ...

Re: Wierd, wierd noise in (I think) gas pipes 7Sep 08, 2012 11:37 pm Lex New house Oh well...there goes the ghost theory! Are you sure it is not coming from the range hood, assuming that you have one of course. I am thinking of the possibility of strong wind generating a variable low pressure area around an opening. No chance that it is in the gas pipe though but noise can be transmitted along different corridors. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

This is in the corner of the kitchen. On the side wall of the house, we have all cooking stuff - gas cooktop, electrical oven underneath it, and a hood above the cooktop (whihc is ducted directly through the bricks to outside (this must be the shortest possible duct in the world!)). Very slightly to the right of this appliances arrangement (about 20-30cm??) we have the gas hot water unit (outside, on the other side of the brick wall). I did listen to this noise many times and it's hard to explain, like blob-blob (?? ). But definitely easily heard around the cooktop where our gas pipes are, and definitely inside the house. Not as high as the hood, though. Some pics: The busy area where I can hear the noise: And the full corner: And the same thing from outside (the top little slab is where the HWU sits): Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Mind you, just noticed that the copper gas pipe on the last pic (the lowest pipe on the pic) drips(??) something onto the sand underneath and creates tiny little cones on 2 spots. Actually, now thinking of it, it might be one of the 2 water pipes above it?? and not the gas pipe?? My signature is distracting people from my wise posts ...

Actually, now thinking of it, it might be one of the 2 water pipes above it?? and not the gas pipe?? Well, it can't be the gas pipe unless it is serving as an unrelated sound conductor. The "blob blob" indicates a physical cause rather than wind/ venturi effect and it certainly sounds like a dreaded leaking water pipe fitting as you have diagnosed. Good luck. 3in1 Supadiverta.

Re: Wierd, wierd noise in (I think) gas pipes 10Sep 09, 2012 10:19 am I don't understand half of it!! but thank you! Eg. sound conductor and venturi effect ... BTW, it might also be related to water hammer which I think might be narrowed down to the HWU ... But why the noise when it's windy outside?? My signature is distracting people from my wise posts ... Re: Wierd, wierd noise in (I think) gas pipes 11Sep 09, 2012 11:40 am Lex But why the noise when it's windy outside?? Virtually impossible to say without being on site. You have eliminated the range hood but l first suspected that the strong wind may have been generating a low pressure area around the vent orifice. As to what that may have impacted on if the sound was heard at the range hood, who knows, something loose somewhere maybe but positively locating the sound is always the first step. The "blob blob" sound is a worry. If the sound is water, the sounds will be equidistant and constant; if it is wind generated, the sounds will be irregular. With the 'cones' in the sand, this is confusing as the sand is obviously outside but you should determine where the water is coming from. Have you gone outside and listened to the gas hot water unit when it is windy? Is it self-igniting? Maybe you are hearing the pilot light blowing out and reigniting. Noises are a headache.

Re: Wierd, wierd noise in (I think) gas pipes 12Sep 09, 2012 1:46 pm I wonder if the wind is coming under the brick sill at the windows and perhaps the flashing (black membrane stuff) is not secured enough, causing it to flap around.

Tel. 1800 326 326 Re: Wierd, wierd noise in (I think) gas pipes 13Sep 10, 2012 9:12 am Hmmm .... dunno ... I am sure it's related to windy days and it's coming from the cooktop pipes. It's almost like you unplug a bottle of wine, but the sound is more much dampened and a tad longer, with some additional twists and notes of literally wind inside pipes! Weird ...

Re: Weird, weird noise in (I think) gas pipes 14Sep 10, 2012 1:29 pm It's certainly not what you think it is... time to start thinking outside the box. Stuff under the bricksills when it's windy, see if it still happens. If it only happens when the gas is "on" then it could be water in the pipes. Ed.

I was thinking if wind could get smehow through weep holes or around the window flashing etc., but the sound is audible around cooktop pipes !

Ed A simple question, I have a fair bit of this going on at my place, I am going to use some silicone around the window flashing, is that what the builder is suppose to do? There are 2 flashings on these windows, the black membrane and the rubber sill flap. The membrane is usually taped to the sarking, but in Lex's case, the pipe under the window would be in the way, so we don't know how that was finished off. The sill flap usually just rests on the brick sill, no silicone required, but no harm is using it if you want. I am suggesting that if the gap under the sill is stuffed (using something handy for now, like newspaper), to prevent the wind entering it might stop the noise, that should determine if the noise is caused by the membrane on the pipe. Then it can b fixed properly Ed "ECOECO" At 'EcoEco', we design windows, we design the best windows, we do it for you, so that when you’re happy we are happy.

I would think it's gas pipes because wouldn't water pipes be full of water?? And how come they are noisy when it's windy?? Although, I do think the water hammer might have somthing to do with the water heater which is right there, outside. So it might all be something to do with water heater ?!
