No gas pressure

Away in the van for the first time since France, filled up with lpg tank took £8 worth. Gas gauge is reading full. But no gas from bbq point or cooker. Valves are on yellow one under van on one under the seat is on but nothing flows. Any thoughts what may be causing the problem?

Do you have 3 red valves under the sink like a 2017 Warwick Duo?

Bizzare. I wonder if there's an air lock? Try the hob, holding the control knob in for some time. If no gas after reasonable time, I'm beaten.

Yes all but all on you can hear the gas flow at the hob but nothing flows. Will check out the tank valve tomorrow morning but we have never touched it.

Sorry but I don't understand that. Does a hob burner ignite and remain on? If so, then you'll need to purge line to BBQ.

Sorry. To clarify we have no gas pressure at all in the van. I have tried the hob and the bbq point no gas flow at all. All the valves are in the on position. The only thing that has changed from when it was working is that we refilled the lpg tank on Monday.

Sounds to me that the regulator has failed, 
If it has had the system since new it may well be that it is passed it "best by" time 
Other idea is if the pipework falls below the level of the top of the gas bottle this may have become blocked.

It is not unknown for LPG to have some oil in and over time they can block/wreck both pipework and regulators on a caravan of mine this was picked up on the Hab check. So maybe a change of regulator and flexy pipe is due. you just need to ensure that if you do replace all piping and the regulator are higher than the bottle so if any oil in can flow back into the bottle.

Maybe the place where you last refilled had a "dirty" lot of gas

Hi. Simple things worth a try first. I think there is a reset button on the regulator, so worth a try. If this does not reset the pressure and flow then I would say it's a failed regulator for sure because you are not be getting full pressure. It's actually quite common for these to gunk up after a few years.

had the same problem with our Symbol last month. Worked one day stopped the next day.
Ours was the regulator had it replaced. It was the original one fitted in 2011. 
Cost of the regulator was about £50 + fitting and a pig to fit as the old  one had been pop riveted from the inside of the van when it was built.

Is 6 or 7 years a typical lifespan for an LPG regulator?

Thanks for the advice everyone. Will have to find a site with electricity tonight.

don't know but according to the fitter not unusual. I have my old and was going to take it to bits to find out what caused it to fail.

Whilst it sounds as if the regulator has failed, it might be worth trying one simple step before changing it. The regulator has a tiny breather hole in it (about the diameter of the end of a paperclip or smaller). That can become blocked by an accumulation of road muck or similar.(Ours was partly blocked by a spray of underseal). If, by some chance, you've recently driven through mud  or spray, it's possible that your regulator's pin-hole is blocked. Not a pleasant job in this weather, but if you can clean the surface and gingerly clean the pin-hole in particular, that might just cure it.

I assume, of course, that the tap next to the regulator, as well as the main control at the tank, is open.

Tap on regulator is open and all clean. Where is the tap on the tank? We have never used it.

If you've never used it, that tap will not be turned off - unless the van has been in for a service since you last used it.

Service engineers should "leave as they found", but they don't always do so.

From reading other posts, it all seems to depend on whether the regulator is fitted above the tank (good) or below (bad). I think liquid flows down and fills it up and causes a blockage.
I have always found AS do these things well and it's hard to see how they could have fitted it below.
I had a quick look under my Warwick and the regulator appears to be on the side! but I'm not really sure and it's hard to see. I will have another look at the weekend.
I think I need to find exactly where the regulator is fitted. I always carried a spare when I used bottles.

That's a thought, although I've never heard of it happening.

You could give Mark at the service centre a phone call. If it does happen, however infrequently, Mark is likely to know about it, and will probably be able to suggest a remedy.

6 or 7 years is too long for one of these diecast regulators.   I would change around 4 or 5 years max.   It is recommended that Industrial Regulators which are more robust be inspected at 12/24 month intervals.
If you have a regulator that is over 4 years old it is likely that is the old type that does not have the "slam shut" facility in the case of impact.

GAS IT have a 10% discount throughout November if anyone needs anything.

Getting the person who fixed the fridge on our mondeo to have a look at it next week, I will let everyone know how it goes. I would just replace the regulator if I was certain that that is the problem.

Well man was due to have a look at the gas regulator today, but at the weekend I gave it another try and after a few goes of moving the yellow lever presto gas pressure at the cooker. I imagine we were the first to turn this off in the vans life when we went on the ferry to france. I may change it next year though.

Van or regulator?

I can suggest a mod that may be of interest - if you're interested of course.
