Just been to fill up and the on/off isolation valve is now stuck closed. I don't want to force it and I'm pretty sure I didn't tighten it to off too much. Any suggestions? Thanks in advance.

Edit: Senior moment, it's actually already open!! :oops:

As a confirmed pedant I was taught to open a valve fully, gently, then close half a turn to avoid damage struggling to open a valve already open and on the stop.

And close gently. Like basin taps at home to make the washers last!

Oh well…..

Why? I fill mine with the valve open or closed, it makes no difference.

This is why Barrie. Copied directly from the Gaslow filling instructions - ENSURE THAT YOUR GASLOW CYLINDERS ARE TURNED OFF BEFORE FILLING!!

Im guessing that in case you had a fault with the one way valve and if you had it will ruin some gas appliances

If the 80% overfill protection fails you get to filling the system with liquid, which if it reached the appliances could when ignited produce a blowtorch effect'

As a precaution, as well as turning off the cylinder valve, I calculate what I expect to need to fill and watch the meter to ensure that the 80% protection cuts off at about the quantity I expect. Maybe sounds OTT but gas is dangerous.

I can understand you reasoning, of course gas CAN be dangerous, but doesn't have to be. I trust the system for now (new installation) and the cut off at 80% works fine for now, as advised by the installer. I do not make calculations of the expected charge.
 
So do you do the same calculation when filling petrol tank?

It may not shut off and hangs about for much longer!

Sorry!

Yes I do actually, but just in order to slow the flow when I get close to the full point, so that I do not get any splash back/overflow, which can happen before the nozzle senses full and cuts the flow.

When you fill with the valves open the pressure of the gas entering your system can damage thd regulator. Closing the valves prevents this.

Barriesimpson is new to motorhoming so we must treat him gently. Hopefully he will learn from here - not the hard way!

Just friendly advice Barrie.

Mines autogas also 😂

There's a 2nd fail safe if the 80% shut-off fails to activate 👍

The over pressure blow out plug 👌

But only if the valve is closed 😱

After that, it depends on whether you go to Heaven or Hell 🤣🤣🤣

Doesn't matter the reason is to protect the regulator.
The regulator is rated for 230psi input, filling pumps are normally around 140psi but they can be a lot higher.
With a new regulator on my van costing over £200 it's not worth the risk & it could ruin a holiday.

Nice enough guy but tends to believe everything his installer tells him & won't accept advice on here. His system has been installed with incorrect pipes from bottle to regulator but his installer says its OK.
 
I have to admit I never turn mine off before filling either . Haven't opened the gas locker other than to close one bottle and open the other on the times it's ran out. Usually overnight which seems always the way.

That said in Spain there's an attendant there as soon as you pull up to the lpg pump so I don't want to give them the chance to refuse to fill. Let them believe its for propulsion rather than domestic 🤣

Yes I know you guys think it is better your way, but if the law in Spain certifies the installation I had done in Spain, then that's good enough for me. These guys have done thousands of installations on motorhomes, cars, taxis and boats too. All certified officially and with the required paperwork. I really don't see the problem.

If I'm going to fill up I always turn the bottles off before leaving my park up.
I really don't want a bu**ered regulator in the middle of a trip.

Ah yes, I get problems with splash back and overflow these days.
Nothing to do with petrol or gas though 🙁

Yes I tried 😂
It’s definitely written in one of the industry standards / codes of practice about being advisable to turn off any LPG cylinder when filling.
This would include all of Europe of course, but I believe it was once said that once you cross the Pyrenees you’re in Africa already 😂⚠️

(I think different countries have different versions of this. In Portugal the north-south thing is sometimes presented as 'Galegos' versus 'Mouros'. Galicians versus Moors. Italy also has its north-south divide I believe. And Africa obviously features in these tales. But in a particular way. Maybe a bit like in Trainspotting where the guy says we were colonised by w****rs, so what does that make us?)

Edit: I spelled the offending word out first, then saw it rendered as 'wabbits'. Wabbits? Elmer Fudd has feelings too you know.

What it is really is all that legislation, rules etc that the UK government used to blame on the EU to make everyone annoyed at the EU was actually cow excrement.

The EU in general Is a lot less bothered.

That's why the guardia civil have huge big steel bull bars on their vehicles. Banned in UK.

They fill non refillable gas cylinders

Building sites have less safety barriers etc etc

Pavements are often a challenge

Diesel is cheaper than petrol

There's more older cars on the roads in daily use


I guess it's a matter of opinion and choice which you prefer but personally I like the less rules and nanny state nonsense.

That is very true. And then some of it is still enshrined in practice.

Do a motorcycle licence and hazard avoidance and emergency braking must be done at a speed of at least 31 mph.

Ah, 31mph. That speed that we all recognise and can feel in our bones, that our speedometers are calibrated to show.

No, it is just the EU 50 km/h.

is that similar legislation the requires uk vans to have hab electrics off when igntions running? that we all really want to ignore.... :LOL:

Yes, what is that about? I had a UK van once that had that. Two German vans since - no problem.
