Swapping Gas Regulator - can it be done?

yes, you can change the pigtail from the reg, but if you want to save money, get  a  safefill bottle, their are not cheap but the price of gas at the pump is £1.00 per kilo, on a 7 k.g. butane the price from Calor is £23.00,  that is £3.28 per kilo  £2.28 difference it will soon pay for itself 

It will only ever pay for iself if you are of EHU and using gas for heating and fridge. I am away 18 weeks of the year and do not use more than £20 (6 kg) of calor propane gas. 

My take on that would be to swap the bottle to a propane ones.  They should do a straight swap to propane if you ask.  Plus it will save you the hassle and expense of a new regulator.  

If you are going to caravan anytime there is likely to be a frost you need the red.  My first bad experience was early November some years ago and the Butane "froze". - 5 outside.  That is of course if you don't go for the expenditure of a Safefill which will save you money in the long run if you do lots of caravan nine off EHU.  

Exactly the right answer, Pippah.

Just change the cylinders to propane cylinders and pay for the gas only - that will suit your regulator and will give you gas that you can use year round.

If you really want to drain off whatever is left in the butane bottles, then you could buy and fit a butane regulator. Can't see the point, myself.

Unforunately in the U.K. the caravan industry decided unilaterally to change to a fixed bulkhead regulator with HP pigtail thus making it more difficult and more expensive to switch to a different gas bottle. This is particularly difficult if you are overseas and want to buy a local gas bottle; they will give you a regulator but that's not what you need, you need another pigtail or adaptor. Thats progress apparently and I have never had a logical explanation of why the change was made.

To answer your question- if the regulator is fixed to the back wall of the locker you don't need to change it. What you do is change the connecting hose. This is easy but check you have a spanner that will undo the nut at the top of the regulator. Then buy the necessary hose and fix it. Keep the old one but in a sealed bag as it will smell.

Yep, that's what we do.

Re Safefill bottles; great idea, we have them but filling them can be a pain.

Swap the bottles 

I would definitely try and swop bottles for propane. The majority use propane and so it follows availability in different sizes is likely to remain high for swapping

Rosie - I think you need to clarify whether your gas regulator is of the type fixed to the back locker wall or whether the regulator fits directly onto the gas cylinder.

Looking at the responses, you might find them a bit confusing. If you could clarify this, then a single answer could be given.

Or, of course, just swap the cylinders to propane.
