Hi all, quick question for you; can a 6kg Propane Calor bottle pressure deteriorate in storage in the gas locker after three years?
Many thanks. ST.

The valve was shut firmly and not used until earlier this month. I bought this bottle at a greengrocers near Battle Sussex September 2022. Got a good mind to call them and explain why a negative review is on its way.

What weight have you got in the bottle compared to when you purchased it. All the necessary information wrt empty weight is on the bottle. Seems somewhat small minded to give a negative review after so long. How can you prove you had it shut off firmly enough?

Well someone will have a chuckle to themselves reading a review after 3 years.
Whatever the reason the the bottle is now empty, it can't be anything the retailer could have prevented, unless they sold you an empty bottle, which I'm sure you would have immediately noticed as it would have been so light? leaving them a negative review would be unfair.

Over 3 years it would only need the tiniest seep from a bottle to make an impact. Given the constant reuse of bottles then the occasional one with a slightly worn thread sufficient to allow a seep would not be unexpected. Really think it is unfair to blame the retailer, especially a grocers shop rather than a specialist gas supplier, 3 years on.

Before leaving a negative review, you should exhaust the sellers complaints procedures. Even if you tried to use the CRA as it is now more than six months since you paid for the gas, the CRA would expect you (The customer) to be able to furnish sufficient evidence that the cylinder was faulty leading to the loss of the gas. At three years I doubt you could obtain evidence a leak being present at the time of purchase.
I seriously doubt the seller was deliberately trying to sell underweight or faulty cylinders refills, as there would be no commercial gain, because the retailer would be buying from a commercial supplier like for example Calor for Flow gas etc.
How could you prove you hadn't opened the gas valve at some point and possibly not fully closed it?
I strongly suspect that you would spend more money and time trying to make a claim against the seller, than the value the gas. and along with the strong possibility of not even being successful with such a claim, you could be landed with the sellers legal costs also.
Probably better for finance and valour to post the experience as "That's Life" And if you feel so strongly about it, double up on checking cylinders for weight in the shop when you first get them.

The OP only says that after three years in the locker the gas pressure has "deteriorated", no information given on weights, or whether it was connected to the system., or the plug inserted throughout that time. In the words of the Bard "much ado about nothing"
Must pop down to my local fruit and veg store and ask them what their complaints procedure is, although it's more likely to be "just return the stuff and we will exchange".

Its well known that calor bottle valves leak about a 1/3 I come across leak , when buying a new bottle for my own caravan I take my gas sniffer. Remove the black bung and insert the probe if it registers gas , I reject the bottle and select another one.Once all seven bottles at the Gas supplier leaked. I also weigh the new bottle and reweigh after a trip , this gives me a good idea how much gas we use per day.If you don't have a gas detector then removing the bung and place a flat piece of plastic( with soapy liquid on it), over the outlet and watch for bubbles. When not using the bottle the black bung should always be inserted in the outlet.It will be interesting to see how the OP can prove has hasn't just used the gas and forgotten!
Even as low as at 10C the vapour pressure of Propane is about 100psi,
The plastic bung surely will not hold the 62 lb force that would be involved?
And much of the time the temperature and so force would be considerably higher.
IMO it is just fitted to keep dirt out, being plastic it can't do much more.
AI doesn’t agree
Yes, the plug or cap, sometimes referred to as a "bung," on a Calor gas bottle is designed to prevent leaks when the cylinder is not in use, but its effectiveness depends on it being properly secured to the valve
. You should attempt to replace the plug if you find a leak, as it helps stop the flow of gas.
I suggest here artificial intelligence has very probably got it wrong?
Unless the plastic used for the plug is a reinforced material then if it stops the flow it would not be withstand the forces applied to the threads. Forces generated as the pressure the plug resists reflect the propane vapour pressures the storage temperatures. If you stop a fluid flow the pressure the other side of a any leak path has to match the source pressure, otherwise its is not "stopped" but still flowing.
No, if it actually prevented a leak then it would have to be holding precisely the same pressure as there was in the bottle. That pressure fluctuates reflecting the changing temperature of the liquid in the bottle. Which at 10C is about 100psi.
According to my instructor on one of my gas courses it was Calor that said it is for stopping a minor leak , however given that as one poster detailed the fact about the pressure of the gas in a propane bottle ( which I know but hadn't really connected , ) is about 7 bar around 20 Deg C and as much as 17.9 at 45 Deg C I now find it hard to see how the bung could withstand that pressure ( it would take a long time to get to cylinder pressure, but it would get there) . Conversely, I am always amazed how many bottles of beer I can fit in my ASDA basket and have never had a plastic handle snap on me yet and I have never seen a bung either with shredded thread or one at the suppliers which had popped out.Finally I am not going try opening the cylinder valve with the bung in place to see if it's OK (10cc :-'rubber bullets').
