Strange noise coming from lpg tank

[wibwob74]

We recently had our LPG gas regulator replaced in our home as the old one was faulty and today i have noticed since its been replaced and the heating has been turned on this morning i am getting a strange whining noise coming from the gas tanks. Can anyone please advise what this noise is please

Don't you need a first and second stage regulator.
Should there not be a regulator at the bottle connection?

Sounds like a pressure related issue.
Could also be the bottle has been overfilled and the liquid is passing out through the valve instead of vapour.

Unit is a first and second

Op is the valve open fully ?
On the bottle
Also the unit valve is shut on the pipework (yellow butterfly) in the pic ??

Sorry the picture was taken just after installation a few days ago so the yellow butterfly is now in the open position. I have opened the valve fully on the bottle after your comment and the noise seems to have diminished considerably. I have moved the bottle slighty and I think it's very close to being empty would that have something to do with it
the noise is still there a little this morning, could anyone advise what the sound is, is it anything to worry about??
