Gas bottle humming

[Sue]

It might be a bit getting towards changing it but could it be that the regulator is dying?

[Phil Ambrose]

Getting towards changing, we have auto change over and that noise always prompts me to check to ser if we have switched to the reserve

Never noticed any noise emitted from my regulators.

[Mike Jordan]

Its not unusual for pressure reducing valves to make a noise as the diaphragm vibrates when the gas moves through.

It certainly happens in high pressure units and in normal garage compressors. A propane reducer sometimes emits a slight noise in

use but I have never heard it from inside the boat. I would not regard it as a definite fault but its always better from the peace of mind angle to replace it if in any doubt.

Hmm!

[DHutch]

I've seen it before, whens your next bss, of it passes on pressure regulation it works, enough said.

It's the regulator. They often do this under light load.

 

Fit a new one if it's driving to nuts. There's no other way to fix it!

"Gas bottle humming". Perhaps it's forgotten the words?

Maybe it resonates more when mounted on top of an almost empty gas cylinder so is more audible

[Jess--]

my regulator is noisy when only the alde pilot light is lit, anything more and it goes silent

Tell Vic to change his socks.

[Sue]

Yeah thanks for the advice. I have a spare regulator and it is about time the gas should be running out. It's not an auto change over but maybe it will shut up when I swap to the new bottle.

 

It isn't bothering me much just wanted to see if you thought it was safe enough to leave as is and it sounds like it is. I'll change the regulator if it stops working.

 

Oh Jaq has a hum on her boat too eh Les?

Beer distribution systems in pub cellars often do this when you change a CO2 cylinder and the kegs top up to operating pressure.

A massive industrial gas regulator we know vibrates so much it gets hot. The cause is diaphragm resonance because the load is passing is way below it's design load.

I was in Toronto last week, and out there a lot of older proerties have the gas pipework and regulator attached to the front of the building just above ground level. Quite a lot of them make a variety of humming and hissing noises that are audible as you walk past.

[Bobbybass]

Mine used to do this an it was very annoying.

 

It was mainly 'Mairzy dotes and dozy dotes.'

I changed it....it it then did 'I've got a lovely bunch of coconuts'...which I found much better.

I had this problem a while ago. Would hum only on one side.

Went to shop for a new reg' and the guy said to try changing the flexy pipe first, which I did.

Problem solved.

That's interesting. I've never actually attempted to fix the quiet humming mine makes. Changing the regulator is probably quicker and cheaper though!

The guy in the shop said that he'd seen it before (something to do with the little washer vibrating) and to try the tail first

as it was cheaper than a reg'.

Mind you, mine was loud enough to make people comment on it.

Is your regulator fixed to the bulkhead with high pressure tails to the bottles? Or does it screw directly into the gas bottle and have a low pressure flexible hose to the bulkhead fitting?

 

If the former, high pressure tails have non-return valves in the ends. These can easily emit a humming noise so my original comment that it will be the regulator is actually not necessarily right.

Sorry for the delay, been out getting wet and windy.

It's the former.
